Hi Alan
Thanks for the reply. My room is about 13 x 20 but open on two sides to other areas and two stories high. One of the things I was curious about after looking at the specs on the two speakers was why the bass response was better on the 80 since they both have 2 6.5 woofers. I thought how different
could it be. The additional drivers would be in the mid and the extra tweeter. But if I understand you post correctly it is the cabinet volume that produces the increased bass? It that true or is there some crossover magic going on?

10 to 14 inches seems reasonable I could probably live with that. I have no problem keeping them off the side walls. I probably could provide 2 or 2 1/2 ft. Let me ask you this. The speakers may end up on a wall with each speaker standing in front of windows. The windows have medium wheight drapes which
could be closed when listening. Do windows cause any problems? Other than the usual UV and heat factor that is?
