Pros: They sound really good, I like the highs and mids, and the lows are good at high volumes.
Cons: Nothing to complain about, you just need a sub to really appreciate the lows.
I purchased two of the Polks monitor 75T for my left and right, they are my first floor standing speakers. They sound awesome, I listen to a variety of styles of music from jazz to to hip hop and they just pound. it's true that if you want the lows to really shine you need a sub. I'm using the Polk Psw108 for my sub, and my receiver if the Denon avr 1913. I also have the matching Polk monitor 45b for my surround and rear for my home theatre set-up.
