jhughesco Posted August 7, 2001 Share Posted August 7, 2001 Does anyone here have the URl to the guy that build a gigantic subwoofer out of his basement. He used a 12" woofer to drive the thing and stated it had some rediculous low end (something like 4hz). Quote Link to comment Share on other sites More sharing options...

Prana-Bindu Posted August 7, 2001 Share Posted August 7, 2001 Steve Decker at Decware (the company is called something else now) built one of those things in their new facility. If you take the online tour of the new company, you'll get to see the whole thing in much detail. You can still get there by going to www.decware.com enjoy. ------------------ May the bridges we burn light our way.... Quote Link to comment Share on other sites More sharing options...

lindee Posted August 7, 2001 Share Posted August 7, 2001 Must have just missed one another. And I think the bottom end was 3hz with a reference to telephone poles. Eric ------------------ You take Visa? Quote Link to comment Share on other sites More sharing options...
montigue Posted August 8, 2001 Share Posted August 8, 2001 I heard from somewhere that anything under 14hz can cause serious liver damage. Don't know if its true or not but the guy who told me this is very knowledgable. Be careful monty R Quote Link to comment Share on other sites More sharing options...
Prana-Bindu Posted August 8, 2001 Share Posted August 8, 2001 If it's causing his basement walls to crack, I wouldn't want to be anywhere near it. Why not build it to hit 20hz only, or filter out the signal below that? There's no way that thing is impressing the chicks.... ------------------ May the bridges we burn light our way....

deaf guy Posted August 12, 2001 Share Posted August 12, 2001 i heard that extremely low end sound will make people go crazy like involuntary movements, bodly functions messed up, they will think they are going crazy in the head, things like that..... well my physics teacher told me that either he was just mesing with me or something but it seemed funny heheheh...... ------------------ bass beats melody Quote Link to comment Share on other sites More sharing options...
eq_shadimar Posted August 13, 2001 Share Posted August 13, 2001 Ok so don't ask me how I know this but in Germany they use ultra low frequencies for crowd control. They have this truck that rolls up and they announce for the crowd to break up and then fire off a warning shot. If the crowd does not break up then they turn it on full power. What happens you ask?? Well you goto the bathroom right then and there in your pants. Yes I said you sh*t your pants. It is pretty hard to be unruly when you have stuff running down your leg.

boa12 Posted August 30, 2001 Share Posted August 30, 2001 rich the klipsch rep here (aka speakerboy) said the mad man who designed the new rsw subs did the sub in basement thing. wonder if that's one of these same guys (?). Quote Link to comment Share on other sites More sharing options...
maxg Posted August 31, 2001 Share Posted August 31, 2001 OK, I have a friend with KLF 30's with a modified crossover that seem to go down to 5 hz (the lowest test signal we have). This is an utterly unpleasant experience that appears to cause 2 main effects. In people - dizziness and vomiting, in buildings - cracks in the walls. I should add that the same building passed through the last Athens quake with not a mark. I have no idea why anyone would want a system to do this - personally I am kind of traditional and use my system to listen to music, but what to I know. Oh yes, he is of the opinion he does not need a sub - cant argue with that!! Quote Link to comment Share on other sites More sharing options...
Ray Garrison Posted August 31, 2001 Share Posted August 31, 2001 Okay, you've certainly got our attention... how in the world did he get response down so low out of those cabinets and drivers? As to why you'd want to... well, I don't know about sitting and listening to test signals at 5 hertz, but my thought is that if the speakers can accurately reproduce signals below 20Hz, then they will do a good job with organs (I'm a fan of Bach's organ music, and have about a dozen different version of the Saint-Saëns third symphony, aka the Organ Symphony), and you'd be surprised how much ambient information is contained in very low frequency bands. Adding a subwoofer frequently opens up the soundstage, an unexpected benefit in addition to the low frequency reinforcement of the music.

Colin Posted August 31, 2001 Share Posted August 31, 2001 driving wears out the body because of the low frequency vibration that the auto body sets up, something like 2 or 5 Hz, if I recall, the auto makers are experimenting with creating ultra low signals to cancel out the vibration and make for a smoother, mor enduring ride ... ------------------ Cornwalls, Bottlehead 2A3 Paramours, Dynaco II, Rotel, KSW200 & LF10 Quote Link to comment Share on other sites More sharing options...
Prana-Bindu Posted August 31, 2001 Share Posted August 31, 2001 Ray: How do powered and passive subwoofers compare generally? Is one generally more linear than the other? How much of a difference does having a subwoofer for each channel (as opposed to just one) make on the soundstage, imaging, and the ambience? Now you've made me curious.... ------------------ May the bridges we burn light our way.... Quote Link to comment Share on other sites More sharing options...
John Warren Posted August 31, 2001 Share Posted August 31, 2001 Ray-I think the Organ symphony is sort of dull.(although I did like it when I was 12 or 13). Like most of "Cammies" works IMO it's largely formulaic. A few pages are memorable but most of the work is constrained, predictable and mechanistic. Cesar Franck, different story. Genius, technically gifted organist, wrote just organ works. Jean Guillou (best organist alive) likely the only person to play Francks' works as he himself did. If you like organ pieces I suggest you audition Guillou's "The Organ Works of Cesar Franck" a 24 bit transcoded to 16 bit Dorian Recording DOR-90135. It's pricey at $30. Best bass I've every heard on a CD too. Quote Link to comment Share on other sites More sharing options...
