Giant Sub-Woofer

Music 392

PuceBaboon sent us linkage to an amusing story about building a gigantic custom sub woofer. I was about to yawn until I looked at the pictures of them excavating a 60 cubic meter hole, and laying bricks. This one might be a little outside the realm of reasonable, but it's damn impressive.

The horn is an acoustic transformer that links the cone to the air in the room very effectively. For good results, a bass horn has to be very large, on the scale of the wavelength of the notes it's reproducing.

The bass you hear on your home hi-fi is most likely produced by resonance, something you should avoid if you really want to hear what those bass notes are sounding like. But resonance is cheap! Large bass horns are neither cheap, nor easy, but they sound so much better...

Perhaps not but you should have seen some very large, very long pipes that accomplish the same function using slightly different principles.

Re:The "Biggest" (5, Informative)

Cheeze (12756) | about 10 years ago | (#8779375)

full-sized church pipe organs are specially tuned. Each pipe plays exactly one note, and the pipe's length determines the wave length. The high ceilings in a church also help.

Re:The "Biggest" (1)

inburito (89603) | about 10 years ago | (#8779379)

Those pipe organs have pretty darn long pipes (at least the ones I've seen) and have plenty of length to produce fundamental vibrations at low frequencies.

That is because pipe organs produce the sound by vibrating the air in the pipe - which you will notice is very long and usually several times wider than the pipes on the other side of the chromatic scale.

Note that you won't get the full range of the subwoofer with a DVD or CD. Both have a bottom limit of 20 Hz, while the sub in question can allegedly output down to 10 Hz flat (and well below that with fall off).

You'd have to use vinyl to get frequencies that low. And have one hell of a damping system for the player to avoid it being shaken by the sound it's reproducing...

Not a vinyl snob (all of my music is on CD and ripped to MP3), but there are technical limitations. Of course, 20 Hz is far lower than most people's stereo systems can reproduce anyway. Below that you can't really hear it... but you can feel it.

Giant American Evil! (-1, Flamebait)

Anonymous Coward | about 10 years ago | (#8779252)

You Americans should be ashamed of yourselves!

Detainees at Guantanamo Bay are shackled for up to 15 hours at a time in hand and leg cuffs with metal links which cut into the skin. Their "cells" are wire cages with concrete floors and open to the elements - giving no privacy or protection from the rats, snakes and scorpions loose around the base. A diet of foul water and food up to 10 years out-of-date has left inmates malnourished. By contrast the camp guard dogs have wooden houses with air conditioning and green grass to exercise on.

But worst of all is the use of vice girls to torment the most religiously devout detainees. Prisoners who have never seen an "unveiled" woman before are forced to watch as the hookers touch their own naked bodies. One said an American girl had smeared menstrual blood across his face in an act of humiliation!

I second that request wholeheartedly. The Iraqi invasion is just one small example of how morally decadent the current administration is.

They hide behind 'patriotism' and 'war on terror' but are merely using these vague terms to execute a policy that was long before planned; miltaristic expansion abroad coupled with slow, insidious repression of rights at home.

With their baseness, they bring shame on the memories of those who were killed on 9/11. They have done nothing but stir up further misery and anguish throughout the world. Where they should have inspired, they have merely frightened. Where they should have called for healing, they have called for hatred.

The Hitch Hiker's Guide to the Galaxy notes that Disaster Area, a plutonium rock band from the Gagrakacka Mind Zones, are generally held to be not only the loudest rock band in the Galaxy, but in fact the loudest noise of any kind at all. Regular concert goers judge that the best sound balance is usually to be heard from within large concrete bunkers some thirty-seven miles from the stage, whilst the musicians themselves play their instruments by remote control from within a heavily insulated spaceship which stays in orbit around the planet - or more frequently around a completely different planet.

Their songs are on the whole very simple and mostly follow the familiar theme of boy-being meets girl-being beneath a silvery moon, which then explodes for no adequately explored reason.

Many worlds have now banned their act altogether, sometimes for artistic reasons, but most commonly because the band's public address system contravenes local strategic arms limitations treaties.

This has not, however, stopped their earnings from pushing back the boundaries of pure hypermathematics, and their chief research accountant has recently been appointed Professor of Neomathematics at the University of Maximegalon, in recognition of both his General and his Special Theories of Disaster Area Tax Returns, in which he proves that the whole fabric of the space-time continuum is not merely curved, it is in fact totally bent.

Not Worth It (4, Insightful)

Doesn't_Comment_Code (692510) | about 10 years ago | (#8779313)

I've built my own speakers before, and while you can do a good-enough job without too much hassle, making a first-rate product is very labor and math intensive. If this guy is putting that much money and effort into this project, I really hope he gets all the damping and power equations right. Otherwise this will all just be a publicity stunt (maybe that's what it is anyway). I'm thinking about the amplifier he needs to run it right now. That's a lot of juice! And juice = money. And worste of all, you'd never be able to use the thing! Even a store bought stereo goes well above the municipal noice ordinances. And bass carries the furthest! What is this guy thinking?

If he ever does use it, I bet he'll feel that really cool thumping sensation in his chest though.

aderusha (32235) | about 10 years ago | (#8779344)

this might seem odd to you, but some people design listening systems for sound quality, not volume. if you'll RTFA, you find that the amp is only delivering 6W to each of 2 horns (despite total power handling capacity of 6400 watts).

The setup is designed for high sensitivity, not high power. He's only feeding them with 400W RMS signals, for 6.4 KW total; here in the UK that'd cost about 30p (about 50c) per hour to run. Not a huge problem.

Quote from the article:

"The real maximum power fed to both subhorn measured with an oscilloscope at the highest musical peak roughly reaches 6 watts per channel."

Now, he's also stating that he calculated for the seating area about 110db/1w/1m. Since my math has gotten quite rusty, I'm assuming with a horn setup that it's quite loud.

What I don't know is if he's doing 6w/ch, meaning 6w to each sub, or 6w to each "set" of subs... so either 12 watts at musical peaks or 96 watts total.... either way, though... watt for watt, this setup would be much more efficient than any setup you could ever place in a car.

Not saying getting loud SPL's out of cars isn't fun, just a different challenge. Usually requires more power, and while you can get a car setup to sound good, working with a true "listening room" (and lotsa cash) can yield almost "perfect" results.

Re:Audiophile (1)

sweede (563231) | about 10 years ago | (#8779479)

the guy isnt running his setup with 6000 watts, only 6 watts per speaker. With that power he will hit ~115db easy. try doing that with your JL 13-W7's and their high 80's sensitivity.

Although you have to wonder one things.

how did he manage to seal the floor to the top of the horn ?!

Too many non-neutral colors for critical viewing. This is also impressive for people who believe tubes are the only way to go, yet tubes aren't known for neutral rendering or good bass response and horns aren't known for smooth response either. I'd say this may be the largest and most efficient home subwoofer (who knows) of its capability but I doubt it's the best. I use 12 18" BagEnd subs in a concrete chamber beneath my home theater.

NeedleSurfer (768029) | about 10 years ago | (#8779422)

indeed, the response time of this woofer must be extremely slow negating any good effect it might produce on the frequency range. First you will need a very powerfull amp to drive it so that you actually hear something and even then all sounds will be muffled, bass and bass drums and explosions won't have any attack because even with the appropriate energy the size and weight of the cone will prevent any sudden movement of the cone. In effect the cone will react slower than the sound going in, providing natural compression.

It will just sound like an aural pool of mud. Subwoofer often need a lot more energy to drive than a tweeter, this is why on bi-amplified or tri-amplified system you will read that 250watt goes to the bass, and 70 watts to the tweeter, imagine what's needed to drive this correctly. Not to mention that at this size it nearly impossible for the cone to be even and solid (if part of the cone are moving before the rest it will just sound, well, disgusting).

Impressive to look at, disgusting to hear, funny to read!

My understanding is that negative feedback improves the temperature stability and frequency response of an amplifier for virtually no cost. Why remove it?

oh, it used to be ultra-common to build echo rooms in sound studios for enhancement of dead-miked voices. while it is not so common now, that's how you avoid creating artifacts and bogosities, big quantities of very dense building material. hope they used acoustic concrete, with extra deadening fibers. otherwise, I'd hate to have to fix the buzz in the bass if a chunk of concrete fell of the brick wall and left a crack.

I've heard Hotblack Desiato used a black hole as a subwoofer at the galaxy twist gig next saturday.

Fans whom have will heard it claims:

-It really rocked!

Walls and ceiling seems to fall down, but don't. The sound pressure is concentrated at the listening point and stopped by a 2 meters high woolglass anechoic wall on the back of the listening position.

Would you dare sit at this listening point? Is this where the Spanish Inquisition positions the comfy chair?

Wooden speaker cones (1)

Now they just need to get these guys together with the guy from the previous article on wooden speaker cones. Together they could buile the ultimate audio system. How much sake were they drinking when they came up with this idea?

Big subwoofer designs (1)

JBMcB (73720) | about 10 years ago | (#8779495)

A guy I work with used to design loudspeakers. He said the editor of one of the car audio magazines had a custom subwoofer system built into his house. There were two towers with 6 12" subwoofers each, a hole driven into the bottom of each tower and ported into the basement (Infinite baffle design) Add a few thousand watts of amplification on a dedicated circuit and you have a system that will shatter glass.

Suspended me in that room..... (1)

thejuggler (610249) | about 10 years ago | (#8779499)

I wanna lay suspended about 5 feet off the floor while the BASS is at FULL volume, no treble, no midrange, just BASS. I don't wanna hear a thing, just feel it baby.

> more bass

For having the gigantic subwoofer and having mandolin music on the giant TV screen.

A far better screenshot would have been "Apocalypse Now" or even a "Quake" game.
