Hi Kythin, I ran T 4s for two years when I was down in Alabama. That is what I had when I met my wife so she knew up front what she was getting into. This is not an easy loudspeaker to deal with. Above 250 Hz everything is wonderful. Bellow, is....difficult. I could never get it quite right. Forget about bi amping for now. You need as much power as you can get. The suggestion for a Sanders Magtech amp used is a great one.
Down the line if you want to biamp you can always add on when finances allows. I got the best performance with the outside woofer panels just a few inches from the outside wall and I put acoustic foam tiles directly behind the tweeter which tightened up the imaging and cooled of that tendency to get a little hot. I did not have time to experiment further as I was moving back to New England, I had a buyer and I was offered a deal on the then brand new Apogee Divas which was back home in Massachusetts. No bargain by the way as the Divas proved to be just as difficult and way more fragile. Good luck and have fun!
