I just bought some Architech wall and ceiling speakers made by OEM. Has anyone used or dealt with this type of speaker? I am putting this into a 12 X 16' room. Two 3-way 8" woofer wall kevlar fronts. A 3 mid range speaker center. Two 8" two-way ceiling speakers for the rear/side speakers. And a Zenith 12" 200watt powered sub. Total about $580 including shipping. This is going to be powered by a Sony STR-DE897 7.1 channel receiver. Can anyone vouch for these Architech or Zenith sub speakers?
