Eminent Tech TRW 17 – Worlds Most Powerful Subwoofer
October 31, 2005 | In: Home Entertainment
The Eminent Tech TRW 17 is supposedly the most powerful subwoofer on the planet. And no, I won’t comment on the fact that the thing looks like a fan.
From the Sonic Flare review of the Eminent Tech TRW 17 subwoofer:
Before you ask, yes, the picture above is correct — what appears to be industrial bathroom fan is actually an “infrasonic” driver. The trick is instead of a paper cone pulsating back and forth, the TRW 17 creates a gigantic cone of air with the fins swiveling to modulate frequency. And whereas traditional subwoofers compress the air inside of a box to create the deep bass, the TRW 17 compresses a different box…your entire freakin room. A smooth $12,900 is what the patented Eminent TRW 17 will sell for (they’re not on sale yet). Also, you don’t want to actually have the TRW 17 in your main listening room (otherwise your head will explode like the guy in the Simpsons THX trailer). A professional installer has to wire the TRW 17 into your attic or basement, thus creating The World’s Largest Subwoofer.

[...] Today a number of stories (@/., @ SONICARE, and @ Gadgetizer) have described the TRW 17 from Eminent Tech which claims to be the worlds most powerful subwoofer with a flat frequency response down to 1Hz! Pretty cool! The concept behind the design for the TRW 17 is explained here. To understand the significance of the design, one needs to appreciate that as the frequency of a sound disturbance in air decreases, the intensity of the sound decreases proportional to the square of the frequency. The main principle behind the design is that one can compensate for the impedance mismatch at low frequencies between air and a woofer cone by replacing the cone with an aerodynamic blade that has some amount of angular momentum. To appreciate the difference, compare moving your hand side to side in the air while standing still, or while sticking it out the window of a car at 60MPH. The unit is intended to be installed in a small room (like an attic) and uses the entire room as a resonant cavity! [...]
