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. 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. 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.http://www.raumboerse-luzern.ch/mieten/bosch-tassimo-manual-de-utilizare 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. 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.

He has done great work replacing the capacitors on my Series IV EQ in the past, and is now performing upgrades on this unit's RCA jacks as well as amp and audio sections. If you haven't heard the difference between an aged EQ and one that has been upgraded, I can tell you that there is a substantial difference in the upgraded system's ability to produce rich and detailed sound. In addition to my Series IV 901's with upgraded EQ, I also have a set of new Series VI.2 901's, and, surprisingly, I honestly cannot tell that there is a great deal of difference between the two. I cannot recommend him any more highly. So make the investment; it's way, way worth it! The speakers are 3.75 inches in diameter without a crossover. If you don't use the eq, then you ain't got no highs and you ain't got no lows so it must be Bose. It is totally the fault of low information listeners (some who's confidence level is truly amazing). Bose 901's aren't audiophile speakers and they never intended to be. They are fun, loud, small, dynamic and retro-cool. Buy a set or two of Series I or Series II speakers and get the eq updated. Awesome! The EQ upgrade made a huge difference in sound quality. My son in college loves them and they will rock the house! I was amazed at how good my bose sounded after Dave finished his work. Great job and would highly recommend to anyone to use Dave. He also called and went over everything with me, and that made the process even more special and put me at ease from start to finish. Great job Dave and Thank you With his repairs and upgrades to my equalizer my 901s are alive again. I had bought the speakers and equalizer a few months before, re-foamed all 18 drivers and thought some of them had blown speaker coils, there was a distortion but could not narrow down which drivers. I sent my equalizer to David. The unit was originally setup for 220volts since it was purchase in Germany in 1980. Whom ever tried to change it over to 110volts mess up, the equalizer board was only getting part of the power needed. After David's repairs these old speakers sound band new!!! Through a series of clear, timely emails Dave helped me decide on several upgrades. He then completed the work in a timely manner and when it turned out my speakers needed more work (NOT related his work) he continued his excellent service by advising me how to proceed.

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. This is the speaker that back in 1968 proved commercial viability of omnidirectional, dipole, and all sorts of bizarre dispersion patterns. This pair was made back in 1987 when Bose speakers were still made in America. The design has not changed since then, and honestly it's almost longer in the tooth than Klipsch Heritage speakers.The drivers also have the ugly looking tinsel leads on the front, but on the plus side the plastic baskets are branded three times along with the dust cap. These drivers are 1 ohm each, and are ganged up in such a way internally to produce an 8ohm load.The rear grills are a molded metal mesh and the clip to cover the back drivers. The rear grill also works to cut the treble response from the rear drivers. If you try running these speakers without the rear grills expect shrillness on a scale that should not exist in the natural world.The port tube design is something I've never seen duplicated, it makes for a very deep tuning without much physical volume. The downside is that these ports can put a candle out from 6 feet away and are audible at full chuff.It's a pretty stout box if you account for all of the holes in it.The idea is that you hook up your wire and thread it through the speaker stands. Then, unless you want to put wood screws into your speakers to attach the stands, you are in for a chore. The dance of flipping the speaker while trying to hold the stand onto the bottom is a contortion that only the 901 owners can understand.This iconic design is really beautiful, if not the most functional. The wire is supposed to run through the top and out of the bottom, but there is no notch for it to slide under on the bottom. Instead the wire just kind of get smashed and the stand becomes slightly unbalanced.The blue line is for the default Bass EQ, the red line is for the secondary bass setting. Yes, that is a shit ton of treble boost, as well as a healthy chunk of bass boost.Choose up to 15dB variation in the treble tone, and 10dB to the mid-bass. I took over the living room and pushed my main speakers into the corner. I ended up at 16 inches from the rear wall and pushed them a bit wider than my main speakers to give them as much room as possible to operate. Now in a perfect world these would have an uninterrupted wall behind them and closer to corners, but I don't have that option so the right channel is stuck on the hallway side. Originally the 901's were to be setup mostly at ear level when seated. The setup for the past 30 years has been tied to these short stands, or hung from the ceiling far off axis. There is even a recommendation for matching pairs of floor and ceiling 901's in some manuals, something I'm sure a few die hards have tried. I'll break it down the performance of the speaker into a few standard categories and how they perform in comparison to other options out there. After initial placement I never once felt like I needed to move the speakers to get more out of them. Imaging is huge and involved, but it is hard at least in my setup to place or pick out specific elements of the music. There is no denying the 901's ability to make you hear all of the music, but because the image is such a blur I don't seem to notice it as much as directional speakers, it instead you get the feeling of it. In contrast, Linkwitz dipole speakers create a soup of sound spread around the room, where the 901's transform the walls into massive speakers.These are some of the loudest speakers I've used in the 200Hz-10kHz range. Setup outside I was able to blast 112dB of non distorted music out of the back of the speakers measured from 10 feet away. The front was limited to about 98dB, which is still pretty damn loud for outdoors. I can see why there is a version of these speakers for PA use. When you start to get above 95dB the bass response falls off as the little drivers can't play deep bass at high volumes. This can also lead to them falling apart before 95dB on complicated tracks that are also bass heavy. For instance most Chemical brothers tracks are limited to about 85dB just because the full range drivers just can't do everything at once.If you sit and listen critically you will be met with harsh treble and bloated bass. Adjusting the EQ to fix these problems will leave the speakers sounding dull as it turns down all of the treble when the worst problems in the cone breakup range above 5k. Bass response is harder to nail down, it's hard to get away from the muddy bass, and honestly the Bass EQ options seem limited to either bloated bass or no bass.Some simple instrumental tracks sound good, but anything with female vocals or cymbals should be avoided. These speakers can be used in a party scenario, and will impress most drunk people with the quantity of sound they produce.My neighbors had to deal with 95dB sine sweeps for 3 hours straight, and then pink noise for another hour. I think you will find the results are totally worth it though.This the most quiet axis of the speaker, so it's not as important as other measurements, but this is definitely not a good start. We are seeing bass response down into the 30's and a jagged sloping response to the treble and a massive 7kHz peak. The jagged response is probably due to baffle reflections, and comb filtering from the 9 drivers all doing the same thing.It's damn near impossible to make out what is happening here, but generally the response gets much louder as you move around the back of the speaker.On the bottom we have the front power response, this is an average of 0-60 degrees. On the top we are looking at the rear power response, an average from 120-180 degrees. Yes, the rear is about 10dB louder, than the front.It's an average of all of the off axis measurements, or the total power response of the speakers, and it's flat. Normally a power response would be tilted to show a roll off of the treble, but it's hard to say that it's wrong given the strange dispersion pattern. Maybe this was the intended goal of the speaker, or maybe it's just a coincidence.This measurement was taken slightly above the axis of the speaker to better represent the suggested listening height. The red measurement is with the speaker 12 inches from the back wall, and the blue one is 18 inches. These are very similar, with the 12 inch being a little nicer. Also, note that the 7k peak is not hidden by the boundary, rear speaker interaction, or even being off axis vertically.I continued on like this until, finally I ended up cutting everything a little. While it definitely sounds better, the correction is far from perfect due to the inherent irregularity of the speakers response.He went through the trouble of designing excellent five inch whizzer-less full range drivers and stuffed 9 of them in a clever box, While it has plenty of flaws, I respect it's performance, blasting off faces and painting walls with sound in a way that no other speaker can.First priority is to get a subwoofer, crossing over to a sub as high as 90Hz can really clean up the sound of the speakers, and will give even more headroom. The second priority would be to add a dome tweeter to the speaker. A stand alone enclosure that sits on top and crosses over to the 901's around 3k with something like a minidsp would fix all of the cone breakup and much of the comb filtering issues. Doing all of this should still leave most of the imaging tricks intact and while it does add considerable cost, there are worse things to do with your money.Micca COVO-S Review! The Dayton B652-AIR is reviewed for great justice. See the inside back cover for Bose customer service offices and phone numbers. The use of 901 Series VI speakers without the 901 Series VI active equalizer will result in improper per- formance. The use of graphic or parametric equalizers, instead of the Bose 901 equalizer, will result in unsatisfactory performance. Figure 2 Pedestal (A) and ceiling mount.
