Onkyo 807 + Bose Acoustimass 10 IV Series + Samsung 58 860 Plasma

Not the right forum, since this is the receiver/amp forum and not the audio setup forum...

But my first advice would be to return the Bose stuff and get something from any number of online or local stores that are in the same pricerange and are not Bose.

Since you already own them, hook them up, listen to them, then return them and get something else, like Klipsch, Atlantic, Deftech, etc.

Bose subs don't hit lows, and if you wanted to build the identical speaker with identical components you would pay about 1/6th of what you paid at bestbuy.

In general, avoid them like the plague. You are paying for marketing. Like monster cable.

807 is awesome, i love my 707.

The MOD will have to move it, but since the only issue here to me are the speakers, I would recommend that you just ask a new question on the "Speakers" board.
