I Got This From The Eminent-Tech Site, Check This Out.

How low can we really hear?The generally accepted limit of low frequency hearing is either 20hz or 16Hz. The answer actually depends on how loud the sound is.Below is a graph of seven different studies on hearing thresholds which extend the Fletcher Munson curves to much lower frequencies. We have been able to verify these measurements in house. Our hearing does not stop at a defined low frequency limit. At 16Hz you need about 85dB Sound Pressure Level, at 10Hz you will need about 100dB SPL and at 5Hz the threshold is about 110dB SPL. This is the threshold, in other words the sound is just barely perceptible, not loud at all. For example most would judge 110dB at 30Hz to be fairly loud. At 5Hz 110dB is just noticeable as a sound, the same loudness as you would perceive 30Hz at about 60dB. In reality, to make 5hz meaningful you need 115dB or better capable woofer at that frequency. Other than the Eminent Technology TRW-17, no other commercial woofer even comes close.More important to understand is the distortion requirements to reproduce these signals accurately because of the slope of our hearing threshold. The Ged Lee metrics suggest it is high order distortion that matters.What we perceive as low bass is not really low at all. It is mostly centered between 20 and 60Hz. Very low bass, well below 20Hz, is entirely different in both perception and physical experience.A cone woofer runs out of an ability to couple with the air at very low frequencies. This combined with our lack of hearing sensitivity at very low frequencies result in the belief that we cannot hear much below 20Hz. If you want to experiment with this try our downloadable DVD that has musical notes and octaves down to 4hz. Sound levels are raised as the frequency goes down to try and match our hearing threshold. With this you will probably get a good idea of how low or loud your woofer goes at a given frequency but be very careful with the volume control.This link can get you the background behind the above hearing threshold graph: http://www.mst.dk/transport....

Evolution Acoustics MMseven Active Sub Woofer (Home Audio)
(4) 15” Treated Paper
Frequency Response -3dB 7Hz-100Hz
Frequency Response -6dB 3Hz-100Hz
Weight 600lbs
85” x 18” x 30 Rated (RMS) 2000 Watts
Part of a system pair.

Is not the most powerful Sub by any means, but definitely the lowest in Hz that I've ever heard of for a conventional Sub. And still cannot move anywhere the amount of air the TRW-17 Rotary Woofer can, which uses the entire room as an acoustical box. The MTX JackHammer 22in. Subwoofer can get as loud as you can take it, but Hz wise can't touch 1Hz!!! Listening to 20Hz @ 160db can do some damage, quite a bit!
But 1Hz 160db would rearrange your insides literally.

Still can't measure up to the massive thrust of air the TRW-17 put out which uses the whole room as an acoustic box!!!
All this talk of MTX 22in Subs & other massive Subs just cannot push the masses of air needed to create 1Hz!!....The
Above mention set is probably the closes I've read about spec wise, to come close to 1Hz in a box.

im good with what i got..... i have 6 12 inch 15,000 watt earthquakes with 2 25,000 watt earthquake amps ive never really tested it on DB but id honestly have to say it hits around 180+ DB maybe idk id have to check but at least 180 the Hz i got down to 15Hz and i wouldnt go lower cuz i could NOT handle that much bass lol........ still id like to hear that TRW 17 in my GMC!

That would kill the purpose of buying it if you'd only play rap crap through it. lol.

Crank some Korn or Tool through that thing and that'd blow your socks off 100 times more.

....lol .... everyone talking about ... " i reached this dB and i got this wattage ... your distortion levels are fuckin ridiculous and the sound and feel is garbage compared to something at 1 fucking hertz ONE HERTZ .... 1Hz ... put enough power in that .... the sound produced at 1Hz will turn your insides ... out ... you can practically create a nuclear blastwave and by blastwave i mean soundwave which destroys everything it passes with the right amount of power running through that thing.

Can your sub re-create hiroshima? i think not so gtfo with your shit ass boasting about dB and wattage at 35 fucking piss poor Hertz ... get back to college and learn something

the mtx jackhammer fail!!!

137db, 8000watts, 22".

I clock 134db @ 45 hz with a 500rms kicker cvr with approx 350 - 400 rms on it. I without even trying, my box isnt even built for spl.

the mtx true 22 jackhammer pushes 12,000 watts of infuriating bass and it has the largest magnet on any subwoofer at 900 ounces. yeah that's well over 50lbs, it has a 6.5 inch voice coil.

will somebody[ by somebody i mean a well known acoustics engineer] plse explain me what technology it uses and how this technology works? how those funky fins vibrate the air particles to produce lower frequencies. my e-mail- gauravsharmaguru@yahoo.com

dude, i can makee that myself. aint no need to spend more than 1000 dollars on sumthin like that. the general idea is its a fan hooked up to a speaker, kinda like when u hook up a batterie motor and bite it or strap a vibrator to your desk. not much different except for its air.

So, Pioneer's team wins the bass compition every year, now they have a sub that they claim to be 'The Most Powerful" the TS-W8102SPL @ 8k Watts & 170dB , shuttle launch (if I'm not mistaken). The TRW 17 creats 1Hz sound at whatever dB,so what. What really matters is the wattage that reaches the listener/feeler. Yes, sound is really measured in wattage, dB is a scale of magnitude. Bare with me if I'm not exactly correct, it's been ten years since I last studied this stuff. For the purpose of measuring how much energy is actually converted into sound you'd need to measure the wattage over a given time, say, ten seconds. Then you could really say which was more powerful. Just comparing dB is like comparing current generation video game consoles by bit (NES-8bit, SNES-16bit, get it?) what really matters is what comes out. And BTW, 'conventional' subwoofers aren't conventional anymore. Carbon Fiber pushed the limits higher, Titanium pushed the limits higher, and now ceramics are pushing the limits even higher. Wait until Carbon Nano Tube materials replace carbon fiber. The only thing that's the same in my subs as my grandma's is the basic shape and a magnetic feild drives both.

People who are so stuck up with the fact that a cone engineered subwoofer is the most powerful because of wattage or because the "company says so"--no fucking shit the company is going to say so... what do you think? "OH, WE'RE THE SECOND BEST, OUR COMPETITOR IS BETTER THOUGH"--amperage, you guys are total morons. Cone woofers are pushed to their technological limits and it's about time they invented a better subwoofer. Remember how big the first computers and processors were compared to that of today and then compare how powerful they are. The bigger is not always better. 1Hz..... be serious... at the low frequency there is ZERO distortion regardless of the volume. 1Hz is also really the frequency of a nuclear explosion. db is nothing when you compare something at a frequency of 1Hz... neither is max wattage... This this essentially has no wattage limit... the more you have, the louder it'll get without compromises in quality... what more can you ask for besides a lower price? So all the white hats stuck up about size and db have to take in account for this NOT being a traditional cone subwoofer.
