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. 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.

The left channel on mine no longer works and I am trying to trouble shoot.I'm also 901 owner. and listener The problem I met was at the first place, the EQ. It's s-IV. They are designed long time ago, before CD and DVD players. And as we know, their output signal is about 2V. EQ s-IV and earlier are designed for tape deck, tuner and turntable signals, which is about 0.5V. The higher signal levels overload the EQ and begin distortions. That's why, if you use players without regulated outputs, or if your receiver or preamp inputs are not attenuated, you'll have problems with the quality of the sound.But you know this very well Lately I use mine with The Bose Spatial Receiver. And even with this old vintage, with dry old capacitors and mash of switches and wires inside, I think, they sound well. And my advice is - don't try to use them without the right EQ. It's waste of time.Btw I think the 901's mid-century modern styling still looks cool, especially the black version and especially when the Bose pedestals are used with them (they were used this way in a cellphone commercial about four years ago, located in a swanky, light-colored modern apartment).OTOH, currently an old vintage speaker as the early series of 901 is much harder to beat than in those days, because the tendency of the sonic quality from today's commercial speakers have become significantly worse, even in the upper price class. Keep this always in mind. I am looking for a diy project with cheap but good quality full range transducers with the same design goals than by the 901, but higher quality.As I recall, they did sound amazing for their size.But for sure, it's not about the price, and for sure results are good By the way, I listen and a pair of 601s s-1, but they are fare from 901s, by my own Resources saved on this page: MySQL 15.79 vBulletin Optimisation provided by. The Series IV was sold from 1978-1983 and its construction reflects this.

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.
