If there’s any speaker spec that’s routinely bogus, it’s bass response. You see a lot of little speakers rated to deliver bass below 40 Hz, but that measurement is almost always taken at -10 dB, instead of the industry standard of -3 dB. Even if the little speaker does hit, say, 36 Hz at some level, it almost certainly can’t deliver any usable volume at that frequency.

There are ways, though, to get legit sub-40 Hz response from a little speaker. One is H-PAS, or Hybrid Pressure Acceleration System, invented by Solus-Clements and now used and licensed by Atlantic Technology.

From an audio standpoint, the CEDIA Expo used to be little more than a showcase for in-wall speakers and other products built mainly for multiroom systems and custom home theaters. But with the decline in home sales over the last few years, the custom market isn’t so hot anymore.
