When the tower is down and the cover is on, do the power tower speakers press hard enough to cause wear on it?
There were some posts here on power tower speakers but more of an amps and speakers discussion. Not much help to solve what you're doing.
I do like the cans off the power tower, but that tower has a more squared off look so as I agree if you can swap you should do it... I also think if you could try before you buy, that would solve a few concerns. (If that's even a concern for you) sometimes you think something will look great until you try see them in place ... Perhaps hear them work too...
