None of the Classic product is in any reviewers hands yet. We are working on production right now, so there won't be product available for reviewers for at least a month. Remember that the typical review lead time will then need to be added, so it's unlikely any reviews will be in print for at least 4-5 months.
Almost all of the improvements in the Classic line are things that you won't see in standard specifications. These include lower distortion drivers, stiffer cabinets with less panel acoustic output, improved dispersion, etc. Some of these things would be covered in a Stereophile review, some wouldn't. The best way to tell will be by listening to the products. Yes, I know it sounds cliche. Soon I'll post a link with all of the product specification and price information.
Why would you use the Three for the center channels? Why not use the 2C or 3C? The Three will work, but it will look funny on your TV. The 2C or 3C will actually have more output capability. Any of them will play plenty loud in an 11x13 room.
In such a small room, I would use the Twos or Threes for all channels, except the centers. In the centers, I would match a 2C with the Twos or the 3C with the Threes. For the low end, a Twelve subwoofer would be plenty.
None of the Classic product is rated beyond 20kHz. Of course it can produce frequencies higher than this, but you can't hear them. Most people can barely hear 18kHz even at high levels.
The Evolution subwoofers have a -3dB point of 26Hz. If you really must have the last 6Hz, it is fairly simple to modify the X1 crossover to drop the -3dB point to 20Hz. However, once you do this, the subwoofer won't be able to play as loud. To keep SPL constant as frequency drops one octave (40Hz to 20Hz), the driver excursion increases 4 times! Keep in mind that as frequency decreases, the ears sensitivity decreases also. This means that you have to generate a 20Hz signal at a higher SPL than a 40Hz signal, just for it to have the same loudness. This means that you end up wasting a large amount of amplifier power and woofer excursion just to get the last 6Hz. The vast majority of people are happier with a subwoofer that produces 26Hz, louder and with lower distortion.
