BASS!

Check this thing out:

Makes frequencies from 1hz to 30hz at huge spl. Apparently you can hear frequencies below 20hz, as long as the spl is high enough.


Need to get one of these at a DnB show! (not that vinyl would contain sounds down there necessarily)

reading that was FAR more interesting than work, thanks Jr Member leezee

I love the first sentence on that site: "Want to hear what 5Hz sounds like?" 

One thing tho, what would you play in order to hear such low frequencies, mastering cuts off anything below ~25Hz

@ $15000 just for the equipment ($10000 more for professional installation) i don't think any of us will be hearing these b-lines any time soon

It's not always a cut though, it's usually just rolled off, so you'll still get something below 25hz.

Not that it would be particularly plesant,that's some seriously uncomfortable territory!

We'll probably all lose control of our bowels.


Would still be cool though. 

That's a myth... but if it wasn't, it'd be worth it 

crank out the good ol test tone cd.. nice big 15Hz burp and you'll probably shit ya pants my friend.

Now, lets figure out how to fit one of these in the VT 

can i play it off cd?

But mythbusters didn't have one of these puppies did they!

Definitely more interesting than work

I'd be quite surprised by the way it would 'sound', if the input signal was just a simple modulation then in theory it should be inaudible because bass requires an element of distortion to give it a sound. Once the distortion is introduced I'm sure this would introduce artefacts at different frequencies therefore giving you your bass sound, but not true 30hz 'bass'. You'd feel the <30hz though.

my 2c

I dunno, I rekon as long as you can physically hear that low you'd still hear the fundamental. Shit like 10hz or whatever you obviously wouldn't, but 25-30hz wouldn't be hard to do at all.

I agree. I think the line needs to be drawn with what you perceive as sound or just feeling air pressure pummet against you

Yeah definately. Infrasonic and ultrasonic frequencies are usually described as "presence" rather than sound, I think that's a pretty good way to put it.

just had this badman buried under my studio floor

that should provide enough bass 


this one wasn't available 



this what me old " bass boiler " looked like after the recent heavy studio session !!! ha ha haaa

TRW-17 Rotary Woofer

http://www.eminent-tech.com/main.html



Subwoofers are one of the most obnoxious yet necessary components in your system. Here, I am introducing you to the Eminent Technology’s TRW-17 Rotary Woofer that has been designed in a way to blow you away. Unlike conventional woofers, the Thigpen Rotary Woofer (TRW) uses proprietary technology to deliver ultra deep bass, much more than the largest and most powerful subs. It has enough output to find resonance frequencies of walls and ceilings in a room and it needs no equalization to achieve flat response to below 1Hz.


The model 17 must be professionally installed in an attic or basement, which is quite baffling. The installation costs can go as high as $25,000. If you want to hear and feel the 4-5 hertz fundamental frequency from a helicopter rotor, the low frequency rumble of wind or the space of a concert hall, the TRW-17 is what you need. All the powerful specs of the woofer are justified by the price tag that reads $12,900.

Dodecasub: 6000 watts of Bass for the Audiophiles

You don’t need to panic, the Martians are not here in this spaceship to destroy our planet! This object is merely an inspirationally designed Dodecasub subwoofer system from Elemental Designs. It brings to mind the gorgeous12 set of dodecahedron shaped Quasar speakers by JVC, which of course look more polished in comparison to this one.

The Dodecasub bears a dozen sides, with 10 subwoofers arranged in an interesting manner. The subwoofers measure 10-inches each and can explode 600 watts apiece. The result is, 6000 watts of blasting sound! This cube look-alike gadget can give you thunderous bass without deafening your neighbors, as it is designed to maintain a very tight sweet spot, confining the biggest boom to a relatively small area.

For all those living in cramped apartments, this thing is an ideal investment. An investment of not less than $2,500, fair enough!
