"Hyperbole galore, the Eminent Technology TRW 17 is, as you shall see, the most powerful subwoofer in the world, achieving FLAT response down to 1Hz. 1Hz! Human hearing is rated from 20Hz to 20kHz but you can actually feel sound way below that -- and so can your neighbors and your neighbors' neighbors. Click the link below to read our take on the most revolutionary bass product this century. 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. And lest you think this is another audio gimmick, comments from the Rocky Mountain Audio Fest have already placed this as one potentially wicked sub. Remember, response is FLAT to 1Hz, meaning there is virtually no distortion. Proper setup is required, of course, but done right, Eminent's TRW 17 is set to take the high-end by storm. Additionally, different versions are rumored: a car version and a smaller one for use in traditional subwoofer enclosures. I can't wait to see some reviews of this beast and, naturally, we'll keep you updated as they come in. I'd request a review sample but, you know, I don't want my system to clip and turn my house into a smoldering crater. So, yeah, I'll leave this one for the professional reviewers (their eardrums collapsed years ago anyway). UPDATE: Go to part 2 for more pictures, comments and links on the TRW 17. Go here part 3. Comments Musical Helo-Tech? Yep, it seems that Bruce Thigpen of Eminent Technology has come up with some interesting new technology, again. Bruce is certainly an inventive fellow. I'm familiar with some of his other designs, he is really an engineer with an imagination. This doesn't seem to be a joke, although practicality is another issue. The technology involved was obvious at a glance, one of those "hey, why didn't someone think of this one before?" things. Helicopters use variable pitch rotors, which can compress air to a rather high decibel level, something all of us must have experienced at some time. But modulating the pitch with musical and infra-musical signals? Well, the demo at the Rocky Mountain Music Festival was done with test tones, a far cry from useful music reproduction, but this does seem possible. Problems with the quality of reproduction quality? Probable, but Bruce has developed some interesting gear before so humbugging would be foolish. Historically, technological humbuggers have frequently worn egg facials. As to why go below 20 Hz? Well, that's what gives the "you are really there" feel. Subharmonics do convince. Big organs also have “stops” that go below 20 Hz. Unfortunately, powerful infra-sonics can actually be dangerous. Yes, an impractical sonic weapon really was tried during WWII, and dropped as a waste of time. However, there are various parts of the human body that resonate quite strongly at various infra-sonic frequencies and the results can run from uncomfortable to deadly. Where I understand that at 11 Hz we are liable to semi-amusing social embarrassment due to loss of control of the afflicted sphincter, other frequencies can produce liver damage and worse. Heating of internal organs and capillary rupture can result. Fortunately, such frequencies generally don't get recorded into music (just think of what would have happened to the audience, artists, or recording engineers...), and certainly not at dangerous volumes. Still, use of such a device should be careful and abuse is also possible. What engineers and scientists create inevitably also gets abused by the less socially adjusted, not to mention the military establishment. Chuckle if you like since it just looks like an ordinary fan since it actually is one, albeit with variable pitch blades...but I wouldn’t humbug this yet, this is an interesting idea. "
