Recently "upgrading" my SR 6200 to an SR 7000 has resulted in my realizing that my PSB Image 6T's can produce good quality deep bass. My question is: 1) For those of you who own the 7PT, how do you like it? Have you compared it to the 6T? How was it in comparison? More bass? No kidding, but how much more, how much better? I don't really understand how the 7PT works. I understand that it has the bottom two woofers crossed over at 200 hz vs the 500 z of the 6T, and of course the bottom two woofers are each amplified with their own 130 watt amp in each speaker, but the top most woofer seems to be a midrange only. Is the top most woofer crossed above 200 hz? How can two woofers equal or better three woofers. 2) Should I pursue more power for my 6T's or try the 7PT's? I want to keep the Image setup but improve the quality of the bass. I'm not bothering with integrating my subwoofer for music for the time being. I'll try more of that later, but first I wan to maximize my 2 channel. I'm amazed at how good the 6T's bass is, so I just want more.
