Thanks for the responses, here is more information: I have essentially a square living room (12' x 12') where my wife and I watch TV. The TV is higher up on the wall, the speakers are in the corners of the room (can't get them out into the room b/c it's a typical living room setup, not audiophile setup), and we sit in lounge chairs near the middle of the room 6' or so away from the speakers. The speakers sound best sitting in the typical sweetspot (no surprise), and they sound "OK" sitting in the lounge chairs (basically because each of us are slightly in front of one speaker).
This is clearly a "back to basics" question, but what I'm hoping for is a more surroundsound type of effect, vs. the current effect of each of us primarily hearing one speaker (and just a little of the other speaker). When I'm sitting in the dining room (adjacent to the open ended subject/listening room), I'm not getting great sound. I know that may not be possible due to the room setup and directionality (is that a word?) of the Cornwalls, but just in case I was missing something, I was hoping to have the opposite of a "sweet spot" effect.
Looks like one option is to mod the speakers to add the smaller speaker on top, that's a cool idea. I'd have to really study it to understand it, because my audiophile language and capabilities are low.
So, it's a basic question, probably a stupid one, but I figured I'd ask! Thanks for your help
