Polk's Monitor Series has been the gold standard of speakers since the 1970's. This current generation features clear, accurate sound with strong bass and exception aural imaging. Polk made the enclosures out of to be uniform in density and not resonate. They've also included ¾" thick baffles to help produce clear lifelike sound.
The three 5.25" cones are made from a bi-laminate composite for an optimal balance of weight and rigidity. The small driver delivers a wide open sound and exceptional responsiveness. The 1" tweeter is a fabric/polymer composite the responds swiftly to the high efficiency Neodymium magnet. The crossovers between the drivers use Mylar bypass capacitors to let all of the details in the higher frequencies shine through.
No matter how good they sound, they have to look good too. Their contemporary look compliments today's flat panel televisions and modern decorating styles. They're magnetically shielded so you can place them near your electronics. The slim design takes up less than one square foot.

Pros: Good, accurate sound. Bi-amp capability is nice and does seem to make a small difference, though not great. Tweeters are well-balanced, woofers provide excellent midrange. Bass response at directional frequencies is better than I expected for a tower at this price.
Cons: You can get acceptable sound without a subwoofer by FM radio / analog TV / VHS standards, which is to say it won't sound terrible, but it won't sound very good either. These really come alive as part of a system that includes a good sub, and conversely they're a waste without one.
Overall Review: Bi-amping these does yield noticable results, but not tremendous. I wouldn't go out of my way for it; any good amp will be able to drive these in a mono-amp configuration with no issues whatsoever. Also, these are pretty big towers, at least by apartment living room standards, and are somewhat bigger than the Monitor 50s. They come almost to head level when seated. They're not going to replace any end tables or anything, but still, make sure you have room. To get the most out of these, pair them with a Polk CS2 center channel, and a PSW125 subwoofer or other good 12" sub. If you haven't already, read up on other speakers within the Polk Monitor series so your configuration will be well-matched. I used these for both front and surround speakers, but I think I'm going with the Monitor 30 or 40 bookshelf speakers (same woofer/tweeter, just fewer of the woofers) for rear surround when/if I upgrade to 7.1.
