Hey all, I Just purchased a pair of Polk Audio TSi400's and really like them. However, I keep thinking maybe I should have gone with TSi500's or RTiA5's. Guess my question is how much difference is there tonally between these speakers? Are we looking primarily at a fuller bottom end, thicker midrange and/or brighter top end? Keeping in mind that I primarily listen to music with a movie on occasion and I've always steered away from systems that are really bright. For reference I also have the Polk CS10 center channel and I'm driving them with a Denon AVR-1913. No surrounds as of yet. The room is large and open with 11' ceilings and hardwood floors.
I know the best thing would be to go listen for myself, but that's easier said than done in this case.
Glad to entertain any and all opinions.
