I would like to connect a set of Bose Wireless surround sound speakers (SL2 to my Samsung 50'' plasma screen TV. Do I need the Acoustimass system to do this?

Question edited for clarity.

It appears to have a funky connection system. Phone Bose and speak to someone in the technical department.

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.

What surround sound system can I buy to go with my panasonic viera th-50px80u plasma tv. One where I can here sound from cable and bluray

If you have it literally conencted the way you say not much good will happen.

The speaker OUTPUTs for the Yamaha feed the INPUTS on the Acoustimass Module then the satellites branch out of the Acoustimass Module's OUTPUTs.

Acoustimass module
Bose® recommends putting your Acoustimass module at the same end of the room as the
television monitor. To prevent interference, keep the module at least 2 feet (.6 m) from the
television.
• You may hide the Acoustimass module behind or under furniture, but do not block the
opening. Be sure there is at least 2 inches (5 cm) between the opening and any surface.
• If the opening faces the wall it increases the bass; if it faces away it decreases the bass.
For the most bass response, place the opening 2 to 3 inches (5 to 8 cm) from a wall or
corner.
• Stand the Acoustimass module vertically or horizontally (Figure 6). To stand it on the
cable connection end, remove the cover by gently pulling it away

Move the sub closer to a wall or corner to increase the bass.

This is a SYSTEM and as such is not designed to be pieced out or separated. I don't recommend that you try it that way. I doubt it will improve the sound.

The entire 5.1 amplification system, in the Bose Lifestyle 35, is actually part of the Bose Acoustimass (subwoofer) module. The RJ-45 (network type) connector passes a low-voltage signal from the console to the Acoustimass module. If you were to hack the connection, and plug the speaker outputs of a 5.1 receiver to the RJ-45 socket on the Acoustimass module, you would blow the amplifier.

If you are really itching to replace the Bose Lifestyle 35 console with a regular 5.1 receiver, I strongly suggest you sell your Bose system, and purchase a Bose speaker system, such as the Acoustimass 10 Home Theater Speaker System, which is made for use with a standard 5.1 surround sound receiver.

Are you useing a digital coaxil cable? or optical cable?(you will need one of these connections to get 5.1 surround!) the white /red rca jacks will not do the 5.1 surround! (back speakers)
Please rate response!

It sounds like one of the internal solder welds to the cable or a/v connections inside the cable box is bad.

me too i want to know
