Scored a pair of series 3.I refoamed all 18 drivers bought a EQ on eBay sent it in for re-cap and upgrade then hooked them up to Pioneer SX 1250.Ha ha heaven.http://milkreplacer.or.kr/files/fckeditor/bosch-maxx-wfl-2850-manual.xml Reviewed Nov 21st, 2018 by Artfrobadoo My buddy has a pair of supposedly original 901s which I have suspicions of being fakes. The wood does not match. There is no labeling. The terminals are crude. He thinks they are the cats meow. So I searched craigslist and I found a pair of 901s for 200 dollars. Then the guy throws in a beautiful working Kenwood KA 7300 amp. I like my Bose 301's better then these 901 VI. Perhaps it's the amp I have the associated speakers to what. Reviewed Nov 02nd, 2018 by OzDaddyBear I have 901 series VI and there i a plug between left and right termina, there is nothing in the manual to advise what this is fot. Any ideas?l Reviewed Jun 12th, 2018 by Mrsteve I have owned two pair of these. The first pair a series IV, the Second pair a Series VI. I took advantage of the Bose Trade-in program some years ago when they still offered it. There are several companies that offer the drivers, and replacing them for both pair is around 560.00-Plus the time involved.I need to do a repair on the equalizer. I cannot find the Series III Service Manual. Thanks To be use for PA system or Karaoke. Any suggestion for an appropriate mixer. I'm looking for resources to help me troubleshoot and repair the equalizer. I don't have much experience, but I would like to learn, and this seems like a fun project. If anyone is willing to help break things down as simple as is convenient, or could help guide me in this process, I would be very grateful. We all have to start somewhere. I refurbished the speakers myself, and would like to say I did the same to the equalizer. Due to purchasing from a second hand store and not really knowing enough about them I consequently now own two right hand speakers. Not sure how this will affect the speakers. While it might well be quite possible to fix, I would be more interested in feeding the speakers from another signal source.http://schlammatlas.de/en/node/18439 The cable from the preamp connects to the speakers via a five-pin 180 degrees DIN plug, and so I think it should be quite possible to connect to some other signal source, the same way I have used a pair of Philips MFB speakers. Am I right or am I right. Anyone have any experience of the 901p active speakers. Or of other Bose Lifestyle 20 substitutes for them? No need to attend a live concert anymore.

Although they have undergone a continuing process of design modification- and the new Series V differs in almost every detail from the original Model 901-the basic concept of the system remains unchanged to this day. Dr. Amar Bose, president and founder of the Bose company, decided that in order to give a subjective effect more like that of a live performance, a similar proportion of a speaker's sound output should be reflected from a home listening room's walls.Before reaching the listener, the output of the rear drivers is reflected from the wall a foot or so behind the speaker, and usually from a side wall as well. The front driver, which provides only 11 per cent of the system's output, supplies the early-arrival information needed for stereo localization. The total radiating area of the drivers in each Bose 901 is roughly equal to that of a 13-inch-diameter speaker, but the high-frequency performance of the small drivers is far superior to that of a large single-cone driver of equivalent area. The 901 uses no crossover network, and an electronic active equalizer is required to generate a flat response in the listening room.http://flexphysicaltherapy.com/images/bose-901-series-vi-active-equalizer-manual.pdf The equalizer, which is furnished with the speakers, normally operates in an amplifier's tape-monitor loop, whose functions are duplicated on the equalizer.Although the drivers are isolated from each other, their outputs are combined through a network of nine chambers, two couplers, and three reactive air columns.Because of its multiple drivers and flat-wire voice coils, the speaker can also handle very high power levels.Black steel speaker stands, 18 inches high, are available as options. Its exterior is gold satin-finish aluminum with a dark-brown plastic front panel and side plates.Actually, an averaged room-response measurement is probably a more meaningful indication of this speaker's performance in a real listening room. We still used our digital IQS FFT signal-analysis system, with close microphone spacing, to gain some insight into the performance of the drivers over limited frequency ranges. Measurements were made first with the equalizer controls centered and then repeated at their limit settings to evaluate the equalizer's effect on the system response. We also measured the equalizer's response with a swept sine wave, as we would with any amplifier or preamplifier.Although it had the usual small fluctuations due to standing-wave interference effects, its average value was a horizontal line from below 500 Hz up to our 20,000-Hz upper measurement limit. Close-miked measurements were made of one group of four speakers on a rear panel, with the microphone close to the midpoint of the cluster.Bass distortion was measured with the same microphone placement used for the bass-response measurement. The distortion level was very low down to 40 Hz, then rose rapidly below that. The amplifier power required at the lowest frequencies was rather high because of the equalizer boost, which reached 17.5 dB at 40 Hz. Around that frequency (and below), appreciable air noise could be heard near the rear vents, although the vents are designed to minimize air turbulence.www.jhannahs.com/wp-content/plugins/formcraft/file-upload/server/content/files/1626bcd0f26c86---concrete-batching-plant-manual-pdf.pdf At 100 Hz, the amplifier clipped before the speaker displayed audible distortion or other signs of excessive cone excursion. The drive level (based on a sine-wave signal of the same amplitude as the single-cycle burst) was about 270 watts into the actual speaker impedance of 16 ohms at that frequency, or 540 watts referred to the speaker's nominal 8-ohm rating. At 1.000 Hz, we could see (and hear) clipping on the waveform from the speaker at 125 watts (into 8 ohms). At 10,000 Hz the speaker output no longer increased when the drive level was raised beyond 128 watts into its 25-ohm impedance at that frequency, or 400 watts into 8 ohms. Although the presence of the equalizer makes it difficult to relate these measurements to those of a conventional speaker, they leave no doubt that the Bose 901-V can absorb enormous power input without damage, significant distortion, or appreciable sound compression. This technology produces Stereo Everywhere performance with balanced sound everywhere in the room, rather than in a single sweet spot. The Acoustic Matrix enclosures house 9 full-range drivers with helically-wound aluminum voice coils to provide exceptional power handling capability, and dramatically reduce chamber noise to deliver well-defined bass. A separately-available active equalizer specifically engineered for the 901 speakers balances the output of all audio frequencies to deliver natural tonal balance and clarity. Stylish floorstanding pedestals are also available as a separate option.

Today's 901 speakers incorporate some 350 enhancements over the acclaimed original. 901 speakers work by reflecting most of the sound off walls and other flat surfaces, instead of aiming all the sound toward you, as conventional speakers do. Just as you enjoy beautiful music reproduction from these speakers, you can also experience thrilling home theater effects from your home theater components. These speakers are an appropriate choice for use with your surround sound receiver, and can be used in conjunction with other Bose home theater speaker options.Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average.

Amazon Customer 5.0 out of 5 stars I had to go out of my way to get audio equipment to support it since most modern receivers don't allow for the pre-amp to be output and don't have tape-monitor circuitry that is needed to connect the requisite equalizer. I connected it to a 200wpc Adcom amp and the sound is incredible. It actually sounds much better than most peoples surround sound systems in my opinion.I have them properly set up, per the owner's manual, and they are pretty awesome. I drive them with a 500 wpc amp, and they never distort. They fill the house with sound, and there's no need to sit in a sweet spot to hear great sound. As for the naysayers, most haven't actually heard them, and those that have, more than likely the speaker's weren't set correctly. Just browse through images online, and you will see them stuck in bookcases, corners, against walls in tight spaces, or turned backwards. As with most speaker's poor recordings sound poor, and great ones sound great. The EQ is a lot of fun to play with on different material. I get plenty of bass, and crisp, clean highs. The midrange is warm, and never fatigues. I listen to everything except classical, and country music. To me these perform best with pop and rock, especially live recordings. Don't pay any mind to the Bose bashing parrots, do yourself a favor and try them.I was in a coffee shop and recall hearing the warm sounds of the 901 series. I could not place where the speakers were located. I asked the owner and he pointed them out. It was a small coffee shop and I was stun by the 3D quality of a stereo set. I bought them and I bought them again at a bargain price after my old ones needed replacement. I have a 20x14 living room and it provides the warm 3D realistic sounds when place properly. This is the key. The music envelopes the room and you can not place the music from the speakers themselves. They are still good today and compete very well with the so called high end speakers for a small to medium size room.Matched with Cardas Golden Ref speaker cables, Cardas Golden Ref IC's, Simaudio Moon W5, AI M3B pre-amp, and Cary DAC, WOW!!!

Other than using a green sharpie to get better CD sound, or that guy that calls you on the phone and osmotically makes your system sound better, no greater myth exists in audio today than that of the Bose 901 speakers. Much like Bigfoot, have you even seen a pair of Bose 901 speakers or, better yet, heard them? My Fiat 500 Sport has a Bose sound system, and yes, it possesses admirable bass extension (so there!) and a wide stereo image from the driver’s seat. I also experienced Bose on a recent trip home from Spain, where I sampled the new Burmester sound system in the latest Porsche 911 Cabriolet, and Porsche was kind enough to fly me home first class. The latter experience came with a pair of Bose Noise Canceling headphones (another product I’d never actually used, but about which I heard plenty of scuttlebutt). I’m thinking of investing in a pair before my next European trip. So that’s two strikes in Bose’s favor. My last memory of the speakers harkens back to a jazz club in my hometown of Milwaukee that actually had the speakers installed into the ceiling by their pedestal bases and powered by a Marantz 4300 quad receiver. Another area venue had their ceiling-mounted 901s powered by a large stack of McIntosh gear. Both systems were pleasant. Not to be outdone, another bar owner installed Magnepan MGIIs from the ceiling, which, coincidentally, ended up being destroyed by a ruckus started by the Milwaukee Rugby Club after a hearty victory. And so it goes. Sure, I love my Maggie 1.7s, but they don’t produce a lot of bass, either, and really need a lot of juice to give their best performance. And don’t even get me started on single-driver Lowthers. Been there, done that, too. Are you thinking mythbusting? Me too. I bought a random pair of 901s via the Web for retail price. I initially tried to contact Bose to see if we could get a review pair, but no one at the PR department would return my call. Hence, there will be less historical data accompanying the review, which is unfortunate, as the speaker is now on its sixth iteration of development and changed somewhat since its introduction in 1968. Unless we get a phone call, this will remain an unresolved question. If I must have a pair of 901s, I can special order them or go directly to the Web site. I do the latter, and about 90 seconds after getting to the home page, a pair of walnut 901s with pedestal bases is on its way. Six days later, the 901s arrive on my doorstep, safe and sound. Next, the listening begins. Will the speakers fall off their pedestals. Stay tuned for Part Two. An Eames lounge chair and an old copy Playboy is all that’s required for the full-on Austin Powers effect. Groovy, baby! However, using them with the metal bases requires wood screws. While the holes are predrilled, you probably won’t utilize them more than a couple times without causing permanent damage to the speaker base. I can’t imagine a company as large as Bose wouldn’t be able to add threaded inserts without raising cost. Yet if you are considering using your 901s with any kind of upgraded cable, don’t permanently attach the bases until you make a cable commitment. I employed Radio Shack’s 16-gauge speaker wire for the majority of listening sessions. The second involves the Sooloos Music Server feeding Wadia’s new 121 decoding computer to the Unison Research S6 vacuum-tube amplifier. At the very end of the sessions, the Pass Labs XA200.5 monoblocks were employed to see just how loud the 901s could play. Because the majority of the drivers face rearward, placement is the key to fine-tuning the imaging performance. If you are used to the sound of traditional box speakers, 901s—when tightly placed in room corners—sound much larger than life and boast an exaggerated soundstage. They feel like the remnants of a hallucinogenic experience. The 901s’ modest size encourages experimentation, which proves equally successful in my smaller 11 x 17-foot living room as well as in my 16 x 25-foot dedicated room. Placed about eight feet apart, eight feet from a couch, and about five feet out into the listening room appeared perfect, and allowed the sound from the front-firing driver to anchor the presentation. Exactly like every panel speaker I’ve used in the room, the 901s were much more interesting on the long wall. Traditionalists, before you cry foul, think of the popularity of DSP-based speakers these days. Bose achieves a similar, if less sophisticated and considerably less-expensive effect with a passive EQ. The manual states the EQ can be used with series V 901s, but earlier models require the proper box. The supplied pair of three-foot RCA patch cords gets the ball rolling. The EQ features a two-position button: position one offering a flatter response, and position two adding a slight bass bump, not unlike the loudness button on a 70s receiver. Finally, there are two sliding controls for mid-bass and mid-treble, the latter claiming the most control over the overall tonal balance. Fortunately, audio pack rat and contributor Jerold O’Brien still has a mint pair of MGIIs to which I listened for direct comparison. Sure enough, they enjoy a softer, more relaxed high-frequency response, just like the 901s. The current MMG we reviewed possesses a bit more treble extension than the original MGIIs, but does not throw as large a soundfield. And, both Magnepan models need a ton of power to get up and go. A suite of Joni Mitchell tunes from Court and Spark, Hissing of Summer Lawns, and Don Juan’s Reckless Daughter captures her voice in the same approximate place as it’s found in my reference system. Sampling a wide range of solo vocalists reveals the importance of the mid-treble slider. Push too much for treble brightness and the vocals become grainy—not unlike when adjusting toe-in with a conventional speaker. Ted Nugent’s “My Love is Like a Tire Iron” from Intensities in Ten Cities equates to an impressive experience when cranked to brain-damage levels. Nugent’s band is spread-out between and beyond the speaker boundaries, and never diminishes in intensity when I get up off the couch to grab another beer. These speakers rock. A quick listen to a handful of bass heavy tracks from Pink Floyd, Genesis and Yello proved highly convincing and again, way more powerful than a number of small stand mounted speakers that I’m very familiar with. Its incredibly wide dispersion comes in a close second. The Bose 901s sound great anywhere in the room, and what you might give up in terms of ultra-focused, sweet-spot listening, you’ll gain in spades when you have a room full of people. These could very well be one of the world’s three or four best party speakers. Again, compromise: Would you like a pair of speakers that you just listen to in your listening chair for private sessions, or do you do most of your listening in secondary mode while hanging out in the house cooking and entertaining? Precious few include components sporting any better quality. I’ve heard a handful of speakers that check a couple more audiophile boxes than the 901s, but I’ve heard many more that sound much worse. Much as I hate audiophile cliches, the “sins of omission” has never been truer than with these speakers. They are so smooth and musical, it’s tough to freak out about the missing detail. When the keyboard enters the first verse of Joni Mitchell’s “Trouble Child,” it’s subdued, as are the bongos at the beginning of “Jericho.” Again, I suspect information is lost in the EQ and through the stock cables. What the 901s sacrifice here, they make up for on a broader scale via the ability to play really loud and without strain. Turning up Ace Frehley’s “Genghis Khan” from Anomaly at a level that hits 100 db peaks proves effortless. Other than plasma tweeter designs, I’ve had my hands on almost everything over the past 35 years. Quad 57s are more beguiling through the midband, the MartinLogan speakers carry more extension at both ends of the frequency spectrum, and the Magepans lie somewhere in between. But they cost more and present greater challenges to a room and system. I found the most lifelike sound came via a configuration slightly counterintuitive to that suggested by the manual. Indeed, my audiophile buddies that I bribed into my listening room with IPAs are still shocked at just how good the 901s sound. As my wife likes to say, “What if Bigfoot is really a nice guy?” Consider this myth busted. But—and like Pee Wee Herman likes to say, “Everyone has a big but”—the 901 gets the essence of the music right. The crossoverless design does a fantastic job with pace, which is what always draws me to single-driver and full-range electrostatic designs. Add a better source and substitute a great tube integrated, and you’ll be shocked at the sheer musicality of the combination. Considering that this model is aimed more at the mass market than the audiophile, the 901s possess more than enough virtue to be considered an excellent value. They are certainly one of the most fun speakers I’ve had the pleasure to hear. Isn’t that what this is all supposed to be about? So forget all the folklore you’ve heard about the Bose 901s, these are serious speakers.But how do they respond to the usual tweaks applied by audiophile to practically every other speaker? For example, it’s very easy to note the variation between the Pioneer SX-424 and Cambridge 740 amplifier, as well as the distinction between tube and solid-state amplification. Again, just as a traditional speaker benefits, the 901s profit from solid speaker stands that are spiked at the bottom. The Sound Anchor stands also make it much easier to take advantage of upgraded speaker cable, as it must travel down the center of the Bose pedestals. Those planning on using audiophile-vetted cable will have to get handy with a large drill bit to modify the stands. There’s no way you can pair Nordost Odin speaker cable with the 901s and the stock pedestal stands. Don’t even think about it. My spirit of investigation encouraged this tact, but it was not my favorite position. There’s slightly more HF extension, but the big, expansive soundfield that makes the speaker so enticing simply disappears. These speakers have been a blast to listen to with every kind of music. While they yield decent performance with a low-budget receiver, they are worthy of journeyman-level components and a modest cable upgrade. Advanced hobbyists could probably uncover even more performance by modding the EQ’s passive components, but doing so is well beyond the scope of this review and definitely voids the warranty. How you go about connecting the Bose 901-series equalizer to your stereo system varies slightly depending on whether you intend to use it in a two-speaker or surround sound setup. If you're using earlier 901 speakers, check for possible compatibility issues with the 901-series equalizer you're using before you begin. These devices might include tape decks and other equalization or signal processing devices. All jacks are located on the back of the Bose 901 equalizer. Connecting to a switched outlet ensures the equalizer is turned on or off automatically whenever the receiver or amplifier is turned on or off. Play some audio through the system and press the “Tape” or “Tape Monitor” button on your receiver. All sound should stop when this button is pressed. When it does, switch the “Monitor” button on the equalizer to the “Source” position. The audio should start playing again. If it doesn't, check your connections and try again. Consult the documentation that came with the receiver or amplifier for more information about which jacks to use when connecting an equalizer. The 901 Series VI active equalizer must not be used with 901 Series I, II, III or IV speakers. Bose is known only using paper cone drivers pushed into unusually small boxes, never publishing frequency response specs, and suing Consumer Reports for giving them a bad review. Even though paper is a good material to use for speaker drivers, and plenty of audiophile companies don't publish specs, the perception is that Bose is overpriced junk. If you have a satellite speakers or a subwoofer, you can thank Bose for popularizing that form factor. If you enjoy a high quality factory car stereo, you can thank Bose for that as well. They were installing EQ'ed Class D active speaker modules in the doors of Cadillac's back in 1984. Bose was doing research using Dummy heads and figuring out head related transfer functions in the 70's that laid the ground work for headphone and VR breakthroughs that are happening now. As for the argument that their gear is overpriced, I've heard much worse for much more. Profits from Bose smart manufacturing, not corner cutting, has funded research that shaped much of today's the audio landscape.
