Question about Bose Acoustimass 15 System

Bose acoustimass 15 series 1 channel loss

Hi, I lost the right front and right surround channels on my subject device. I checked my receiver by plugging in other speakers to each channel, checks ok. I checked the speakers by confirming they work on other channels and did the same with the wires, all ok. I popped open the acoustimass module and checked the D connector, and looked on the boards for a fried or loose component, nada. I pulled all of the connectors and reseated them, still no luck. What else is left?

Sounds like you may have a blown output transistor or chip, which generally show no external signs of damage. This would take an experienced technician to find and fix, and I commend you for knowing to check the speakers, receiver and cables through substitution! If you're handy with a soldering iron and can find the parts, try replacing the output transistors or chips in question. These are what usually fail in audio power amplifiers - also check any power resistors for opens - some of them are designed to act as fuses to protect the more expensive components.

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.

Hi, I bought a Bose acoustimass 16 - 6.1 channel, iam curious to know which receiver is suitable for that.


I would get a receiver that puts out a little less power than the speakers can handle. This will prevent you from blowing them by sending too much power to them, but will still send enough power to make them sound good.
An example would be, if you're speakers have a combined power of 500 watts get a receiver around 495 watts or a little less.

Is the subwoofer from the Bose acoustimass 10 series IV Home Entertainment Speaker System a power sub?


The entire speaker system is passive. That is, it requires amplification for each channel.

From the manual: "Compatible with A/V receivers rated from 10 to 200 watts per front channel and 10 to 100 watts per rear channel; rated from 4 to 8 ohms".

Best amplifier for bose 901 VI speakers


By all-in-one amplifier that handles the surround I think you mean all-in-one receiver or preamp. Amps are just big dumb muscular power supplies for speakers.

The source control and digital decoding could be handled by a modern AV receiver with multichannel analog outputs for driving separate amps or you could get a digital AV preamplifier/control unit functionally like this Adcom. Prepare for sticker shock.

http://hdtvdreams.com/Adcom-GTP-870HD-7.1-Multi-Channel-Processor/Preamplifier-GTP870HD.aspx

Understand that EACH PAIR of Bose 901's will require its own DEDICATED two channels of amplification AND someplace to jack in its Active Equalizer - between the line level source and the power amp.

Conventional speakers can probably run off the receiver's amplifiers since they don't/can't/must not have the Bose Active EQ in line with them.

Having a single pair of 901's plus a passive subwoofer or two in the same room for accurate 6- or 7.1 surround would require at least four stereo amps or some combination that adds up to 8 channels.

In my own system I have a Pioneer VSX-36TX Receiver (with 5 potential channels of amplification for Left, Right, Center, two Surrounds) doing light duty as the control and routing center but ONLY driving the Center (two Kenwood 777's) and Surround speakers (Bose 301's). I have a Carver 5-channel amp pushing the Bose 901 Front speakers (100Wx2), two dbx Subwoofers (110Wx1) and the Bose 301 Rear Surround speakers (60Wx1).

You could probably get by with a powerful 2-, 3- or 4-channel amplifier to push the 901's and subwoofer(s) as I did. It's the cheapest way out if you get a decent AV receiver. Once you set up the levels and delays the receiver does all the thinking and controlling for you.

How to hook up bose series 2 eq to onkyo tx sr 875 receiver.?


I wrote most of this for a different receiver, but if you account for minor differences to your receiver this will work just fine.

There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.

The good news. I have a setup similar to what you want to do and it works great! I see on the SR875 there are Pre Audio OUTS. This is easy.

A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.


Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

I lost sound on one side of bose stereo system., Seems its the power ouput on the right side speaker, i changed speakers and the right one works when plugged into the left output. How do I open the bose...


first lets check
no need to open any thing

1) just trace the wire of working channel and plug out that and connect to opposite side of that channel


for example: if front left is not working, remove pin of front right and plug it into front left

after that listen the sound if front left is working then no need to open amplifier just check the wires of satellite speaker which is not working

how to check broken wire:

1) just observe your speaker nearly if you found any screw holes open it, if u can not find any screw holes remove front net which is fitted by press lock or any stepped groove, you can remove that and if you are removing front net you have to open speaker from casing then after you can find speaker's wire shouldered or bolted to it just check wire and go on after that u'll be sure that weather your speaker is failed or wire!!!

enjoy!!!!!!!!!!!!!!!

Left Channel Not Working.


Has it ever worked?

Try this - connect one pair of its speaker wires at a time and test it. Watch the polarity.

• Make sure all cube speaker arrays are connected to the proper terminals according to their
position in your room.
• Check to be sure all wires are connected to your surround receiver with the proper polarity
(+ to + and – to – wires). Incorrect wiring can result in a total loss of module output.
• Correct any wiring problems before you plug in your receiver and turn it on.

How do you know the receiver's Left channel isn't the fault? Sounds like a source issue.

Compatable receiver list for Bose 901 series VI


I contacted the Customer support folks at Bose. Here is what they said: With a stereo receiver, the equalizer is run through the tape monitor section in the back of the receiver. The receiver's tape monitor output, left and right, runs to the amp input section of the equalizer, left and right. Then the amp output section of the equalizer, left and right, runs to the receiver's tape monitor input section. With a surround sound, home theater, type of receiver, the theory is the same, but the connection is through the preamp-out/ main amp-in section of the receiver. Not all receivers have this feature. Most, in fact, do not. Check the back of the receiver. There would be a connection made by two U-shaped clips. The plugs would be pulled out. Then connect from the preamp-out to the equalizer's amp input section; and from the equalizer's amp output section to the main amp-in. This effectively isolates the equalizer so that it is not affecting the other speakers in the system or the receiver's surround processing. Attached is a current list of known 901-home theater compatible receivers:
Note: Specifications subject to change without notice. Bose Corporation is not responsible for any inaccuracies due to manufacturer changes. Inclusion in this list does not indicate an endorsement by Bose Corporation. When in doubt contact the manufacturer of the equipment.

I have the list in a pdf document but do not see a way to attach it.
