...a little pricey, but I can think of a few talkbassers that could put this to good use.

Is this a new design, or has it been done before?

Its only $12,900 -- I'll just go ask the wife

" Want to hear what 5Hz sounds like?"


I sure as hell would, pity the human ear won't pic it up, you'll feel it tho, thats about it

$12,900 without crossover or amplifier, in-fricking-deed

Dont think even TomBowlus would get one of them (or has one yet)

I don't think you can hear as low as that thing goes, but then again what you can't hear I bet you can feel Almost as good of a deal as the PJ tube head.

Note, the model 17 must be professionally installed in an attic or basement which becomes an infinite baffle. The price includes the driver, enclosure, baffling, filters, motor, motor speed controller, motor mounting bracket and installation instructions. The amplifier should be capable of operating near its rated power at between 1 and 3 Hz.

Um...yeah...anyone have an extra attic to annoy the neighbors with sub-sonic rumbling? This is the kinda thing designed to replicate the sound of space ships for sci-fi dorks, um...I mean afficionados.


12k for a fan.

Reminds me of a servo motor sub.

You can't hear 5Hz. The only thing on your body that responds to 5 Hz is the skin on your technicals, that gets wrinkly in response to low freq energy.

All things considered I think it blows.

lol, ya beat me to the punch. I believe Jauqo and stew mac could use one of these though!

I concur.

If ever there was a driver that could deliver the elusive "brown note", I suspect this may be it.

...That is if you don't sh!t yourself for having spent 13K on a sub (sans amplifier) first, of course.

Neat toy, though. I'd really like to hear my subcontra seven through it...

 

[ModulusFan]

It goes to -20Hz with a tara labs power cable.

 

[DubDubs]

And I'm sure you'll have an easy time finding an amplifier that can reproduce .5hz...

 

[iammr2]

Fans are on sale at Walmart. You can save some cash....

 

[SuperDuck]

But is there a switch for changing impedances?

I'm impressed ... what a great idea ... one of those 'why didn't I think of that' because it is so simple.

The motor isn't much more than a fan motor ... it's apparently the voice coil tech and control technology that are expensive. A 1/3 horse power motor turns the fan blades, which are connected to a rod in the center of a woofer voice coil. Instead of the voice coil moving a cone, it moves the rod, which then moves smaller rods that adjust the pitch of the fan blades. So, the high velocity air coming from the fan is pulsed at the low frequencies. It only takes about 100 watts of amplifier power to drive it.

Here's the description "The entire room shook, and the door was opening and closing in time with the signal. All this, and there was almost no distortion (the ET rep had the response being plotted on a spectrum analyzer during the demonstration). They calculated that it would take ten 18" subwoofers to produce this level of sound. It has to be placed in a separate room due to the fan noise, and putting it in the attic would work fine. The opening into your home theater would be about 2'x4' in the ceiling."

Hey, if it wasn't for the disclaimer:

I'd be on it!





Actually, I did recently pick up a Bag End 1x18 ELF system, which basically accomplishes the same thing, and can actually be moved from place to place!
