Got to hear the new designs at Best Buy on the day after Thanksgiving. I thought they were an improvement over the older designs. Strengths: -Niche product - Still the smallest thing out there so if it has to be invisible these are the smallest speakers -New Transmission Line Acoustimass module - Seems to go deeper than the 8th-order Bandpass designs -The Acoustimass module for the AM15 and AM16 offers 3 woofers for louder output -The prices between the older Acoustimass systems and the newer Acoustimass systems are unchanged so you get (slightly) more for your money Weaknesses: -Still poor frequency response (varies +/-10dB!) -Crossover point to the "bass module" is too high (which means that you can still pinpoint the location of the sub) -Bass from the Acoustimass module is still very boomy -Bass module still uses 5.25" woofers (good for maintaining a narrow profile, but at the expense of a lot of performance) -Still Overpriced ($30 worth of drivers sold at $1299 in the case of the AM-15) -Seems very much like an overglorified set of PC speakers *In looking at Bose Acoustimass systems, one must take into account that these will not give you true home theater performance, and much better sound can be had for much less. These remain having the best WAF factor (because of their size) but if you actually intend to listen to these for a long time then forget it. These are status symbols ("Wow, you can afford Bose!") for those who like to show off their money, not their sound system. These speakers quickly cause listener fatigue. That said, it's a lot of fun to watch that little 5.25" woofer go. And the Bose system might be okay for apartment dwellers who have easily-annoyed neighbors because it won't shake the walls.
