Question about Bose 901 VI Main / Stereo Speaker

Bose 901 repair...

I'm not sure which series I have, but I have a set of 901s. One of them has what appears to be a short in the wiring somewhere, and I need to take a look at the wiring between the diodes and the drivers. I have had liitle success in finding a guide for accessing that wiring. Is it possable without disturbing the vacume?

Bose 901s series 1-6 are all wired in the same way. that is nine one ohm full range drivers wired in series to produce around 8 or 9 ohms. No way it can be a short, think of the old christmas lights that were wired in series , one light went out, they all went out. I would check the wiring first to make sure no loose connections exist. The only way to access the wiring is to remove each driver from the cabinet. If all wires are intact, You may have a damaged driver. A simple test with a ohm meter will tell you. set to lowest ohm setting, each driver should read 1 ohm. If your speakers dont have the air tubes in back, you have series1 or 2 removing the drivers will not affect the vaccum, just replace the gasket material around the drivers.

I have a Bose Acoustimass 6 Series III the receiver is Yamaha 3066, this system is a 5.1 surround sound. Then I bought a pair of Bose 901 Series VI Direct/Reflective speaker system with active equaliz


The setup is possible, but with several compromises. First off, to use the active equalizer, you'll need to insert this into one of the 2 channel AV channels limiting your listening with the equalizer to stereo only. The acoustimass subwoofer acts a driver/power regulator for the little cube speakers. It probably will not be able to drive the 901s at the correct level when attached to the Acoustimass unit as front left/right speakers. You could try running a dedicated set of speaker leads to the 901s which may work and still allow surround sound, but you'll lose the equalization capability on the 901s.

Bose 901 equilizer connections to sansui G901DB


It sounds like you may have only the 901 loudspeakers, and not also the companion 901 equalizer box. You must install the 901 equalizer properly--using the tape monitor loop of the G901 receiver. If you of not, the 901 loudspeakers will perform poorly.

Not sure of how to wire these speakers ( internal ) Bose 901 series iv


Found on Google Search: "bose 901 internal wiring" You must first identify which series you have. The first two series were acoustic suspension, and used nine 8 ohm drivers in a series/paralel configuration. Series III through VI used nine .9 ohm drivers all wired in series. Series III and IV had an additional terminal for use only with the Bose Spacial Control Receiver. Series III through VI are easy to identify, as there are three ports sticking out the back of each enclose. The 1st two series have no ports.

Hi -

Sony CD player Red / White RCA - > CD input RCAs on the Arcam.

From the Arcam Preamp Output RCA's, go to the Bose "Input". From the Bose "Output", you need RCA splitters to make them into four outputs to run your amplifier connections.clmrt5000_2.jpgclmrt5000_3.jpg

I have a Harmon Kardon AVR 247 and I want to connect with Bose 901 VI equalizer. No other speakers are connected, just the 901's. Where do I connect the wires from the equalizer to the AVR 247...


I have this exact setup. 901s are my Mains.

The AVR247 has PreOuts on all of the channels.. No jumper to remove either. Just get a power amp or two and place the 901 EQ between the AVR247 and the Power Amplifier.

I have a set of 901 IV with no equializer, I am


As far as I know, any equalizer will work. There is a guy on here that might know more about them, but I never had the Bose equalizer and I have Bose speakers for 35 years. The guy at the electronic store back then sold us a little equalizer at first, we graduated from that a long time ago, and now on the 3rd or 4th one. No problem, works great, sounds better than ever. Hope this helps.

I am looking to upgrade my receiver to an audio video receiver that will hook up to a blue ray via HDMI. I want to use my 901's forthe front speakers. Can you recommend a mid priced (<$600) AVR that...


Good day,

Congrats on your new AV receiver. I own an awesome Yamaha mid-priced AV surround sound system with HDMI, BR disc player, and all that stuff. However, I'm old school and use my 901 Series Vs with a Yamaha RX-797 'two-channel' receiver. To get to the point, I have some bad news. Mid-priced (mp) AVRs, or any AVR for that matter, will not work with 901s because the active equalizer (EQ) requires either a 'tape monitor loop' or 'pre-out / main-in' connection to work properly. You've probably been told the 'why they won't work' by now and it is very true--I know from experience. Most of today's AVRs do not include a 'tape monitor loop' or 'pre-out/main-in connection for the EQ connection, thus, killing all hopes of using 901s. I truly love my 901 Series Vs (since 1985 and still kicking) and love true 'stereo' for playing my music. Again, 901s are useless with today's AVR equipment (as I know it). Just don't let your 901s collect dust--they are truly marvels!! Go with a set of good 'standard' speakers for the AVR system and buy yourself a decent stereo receiver or amp for the 901s--that's how I do it!! I've tried Onkyo, Rotel, Sansui, Poineer amps / receivers--all of them. I can tell you this--for the common, working man/woman, nothing, I mean nothing available can match-up with Bose 901s like a Yamaha RX-797 (200W)--not to mention the sound quality-wow!!! And this unit is very reasonably priced for such awesome performance and high quality build. Just know that all is not lost. You can still use your 901s--I cna't listen to music without mine.
