Summary: These are really nice looking speakers right out of the box. The tops are shiny black and black wood grain looks nice. I am running them with a new Onkyo TX8020 receiver and new POLK PSW10 Subwoofer. I just wanted a simple set-up for radio, cd's, and mp3 player. These TSI100's sound great. They have crystal clear highs and a strong midrange. They are ported on the rear and push some air. I believe they can take everything my Onkyo TX8020 will give them.
Summary: These function as my surround speakers. They don't get very deep bass but with the right accompaniment of other speakers they sound great. I wouldn't want these for my main speakers or center channel due to the lack of bass but they're perfect for surround. Nice rich sound, as you'd expect with polk speakers.
Summary: First, these things are pretty to look at. Now, that's not the important part of speakers, but they look amazing. Thankfully, they also sound amazing. Really great response from a bookshelf unit. I've tried them on a couple different amps that I have they are bright, clear, accurate and quite loud. Also, for their size they still pack quite a bass-punch.
