Summary: I am very satisfied with my choice and the sound advice Crutchfield people gave me in making this choice. The 300s sound very good in my 11X11 studio with hardwood floors. No subwoofer required since I listen mostly to jazz and classical music.
Pros: Quality sound at an excellent price, well suited to my music and my space. I don't need to but for fun I plan to bi-amp them.
Summary: I sold Hi Fi...OK, mid fi, back in the day when Polk was just making their mark. I loved Polk speakers, they were the Toyota of Hi Fi back then, they just went about making musical speakers and allowed beer budget, budding audiophiles a taste of the good stuff.
Pros: Smooth, musical, wonderful bass, smart looking in a small footprint. Bi-amp capable. Sound great on a variety of music. Don't need a lot of power to shine. No serious flaws, affordable almost audiophile sound. Polk continues its tradition of hitting above its weight. Many hi end speakers fall sho...
Cons: Splashy high end, less punchy dynamics than some competitors. A little chesty sounding. Nit picking, really.
Summary: The TSI300's are very nice! they sound great with my Yamaha RXV-465. When I hooked them up, I thought they sounded distorted on the low end. The bass just would not come out smooth no matter how low or high I adjusted the bass. I added a Polk sub and got the same results. The sub was distorted too.
Pros: Sounds great and they ain't cheap looking! Can't go wrong with the 300's
Summary: I've had these speakers for over 2 months now and I use them in my 3 bedroom apartment on a University campus. Not only are they enjoyable to play casually, but they are loud enough for parties and luckily haven't drawn a lot of attention from law enforcement (so far).
