Speaker question Can I link three bose cubes together to make a center channel speaker? i have a Sony Es receiver and i am currently replacing my bose speakers. This will be temporary, the bose system has one cube for a center channel and i thought I could get more sound if i added two more since i am not using two of the cubes that i replaced.

Bose 901 speakers are designed to use with the Bose equaliser patched between the pre-amplifier out and power-amplifier in of your receiver. Having said that, Bose did not invent EQ, neither is EQ a mystical process. Not sure which series 901s you are talking about, but I would definitely be experimenting with the built-in EQ supplied with your Sony DA5800 ES. The manual says you have +/- 10 dB of adjustment for treble and bass for each of the surround channels. That is not really adequate in my opinion, not only would I be seeking +/- 15 dB, but I would also like to be able to apply those adjustments at frequencies chosen by me, not just 'treble' and 'bass' To use the Bose EQ, it needs to be patched between a preamp output and power amp input. The Sony DA5800 ES has preamp outputs, so you could use these (Note that the built-in EQ is disabled when using these outputs) In this case you could either feed the signals back into the Sony (post Bose EQ) perhaps using a different 'Zone'. As an alternative option, you could power your 901's with a stand-alone two channel power amplifier. Then you get the full benefit of the Bose EQ as well as the surround sound from your Sony (front L+R speakers off) It all sounds like a lot of fun. Happy listening! Cheers, Don.

Plug the speaker wire from the speakers themselves directy to the receiver or you can plug them into the acoutimass module and the module into the receiver using speaker wire.

It sounds like you've read one of my many posts on 901 deployment in the AV world.

Functionally, what is the difference between one amp with 'x' channels or 'x' mono amps? Nothing. Pre-outs don't know or care what else an external amp does.

According to this link http://www.ecoustics.com/electronics/products/new/642968.html those amps are 2- and 5-channel, respectively.

There was a time when I had two bridged-mono Carver Cube atmps (at a real 400 watts) pushing one 901 each but that was big time overkill.

I now use a Carver AV-406 (functionally the same as your MM7055) with the 901 EQ in between the AV Receiver's front pre-outs and two 110-watt channels. Other channels on the AV-406 pull subwoofer and surround back duties. My AVR directly powers only the center and surround speakers.

The MM7025 would work for you.

The Bose speakers with the cubes and bass module are all interconnected with a proprietary cable available from Bose, if lost you get a replacement by called 1-800-444-BOSE.
When you connect the speakers all wires run from the receiver to the base module first, then out to each of the speakers. All terminals on the bass module are labeled.
The Bose cubes are all identical and can be used in the front or back positions.
Try to keep them at ear level or aimed at the listening position for best sound.

you need to run the left speaker output from the amp to the left speaker input on the Bose, the right speaker output on the amp to the right speaker input on the Bose, the center channel output on the amp(assuming it has one), to the center channel input on the Bose...then the right output on the Bose , to the right Speaker..the Left output on the Bose to the left speaker...and finally the center channel output on the Bose to the center speaker

Get a separate amp for the 901's and the rest falls into place.

1,2, 5) Place the 901 Active EQ between the pre/main front OUT of the receiver and the TFM-55X. Attach the 901's. Keep track of the jumpers you remove from the receiver. Or replace the jumpers with RCA splitter cables so you still have pre/main connection but can share the output with the TFM.

3) Pinnacle subwoofer (self-powered?) to the subwoofer out of the receiver.

4) Bose (AMS???) 5. As surrounds on the receiver. Place the sub module toward the rear so it mates sonically and directionally with them.

What? No center speaker? I'd get something more robust with bass capabilities, like a pair Bose 301 series 1's because the tweeters face in one direction only.

Except for the amps and the cube stuff that is essentially what I have. 6.1 with full-range speakers everywhere.

check to make sure you dont have a bad hdmi cable thats what it sounds like is stereo balance set to the middle on the receiver.

Why not? People have been known to run them with lesser receivers and sources.
