The Powertowers I have now are excellent speakers. But since I moved from my house into an apartment I just can't them to sound the same, they need room. Now I am confined to a 14'x16' listening area. They have 400Watts subs build in. I am driving the tweeter and midbass (midrange) with 350 Watts. Maybe I should try some roomtreatments first? It is just amazing what a difference a room makes for system, it can make it or break it. So I was just thinking maybe nonepowered towers would sound better. The towers I have are in the 5K range and they are excellent, just can't seem to able to finetune them. What I do now I just run the tops and turn the plateamps off and just use my 2 other subs.
