Bacheaudio: 002 speakers
Bacheaudio was demonstrating their 002 loudspeaker. A semi-unconventional design, the 002 features an active 10” woofer with a bass level adjustment. A level control hardly seems like a breakthrough, until you consider the large variations in output below 100 hz experienced in real rooms with real seating positions. It practically defies logic that the low frequency output of a speaker should be held constant in all these cases. But, most speakers and electronics stacks do not allow this adjustment.
The woofer is crossed over to a 10” paper cone mid-woofer. The main driver is an 8” bamboo fiber midrange/tweeter which is run without any crossover. To support frequencies above 10 kHz, a Fostex super tweeter is used, and this also features a level control.
The goal is to create a high efficiency speaker with controlled directivity. Rated at 96db at 1 meter, the efficiency is high enough to allow use of SET or other low-power amplifiers. Bache demoed the 002 with a 15 watt per channel Alexus Audio SET amp.
The sound was nicely dynamic, with good balance and imaging. I was surprised at the smoothness of the response in the sweet spot. This speaker made me wonder about the potential for high sensitivity (as with horns) and controlled directivity (as with horns or dipoles or omnis) to mix dynamics with spatial accuracy. And to fully exploit the dynamic possibilities, it would be interesting to test speakers like these with bigger than SET power.
The Bacheaudio 002s are priced at $22,500 per pair including the bass amplifier and your choice of a variety of solid wood finishes.
