Low Frequency Subwoofers

i need to know what kind of subs and box do i need to get the lowest frequencys out of them. i already blew 2 cerwin-vega Vmax 800 watt DVC, in a vented box, put new kicker comp vr in same vented box but did not get the response i wanted i am thinking of Infinity perfects or kenwood excelon.zuhare

1 Single Adire Tumult 18" on paper it looks like it should make you crap your pants at 20hz2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

the box didnt sound good cuz it wasnt built for the subs. you need to find the specs on your subs and have a ported box made and tuned to 40-50 htz, for low frequencies. its all about the box.

are you able to hear the subs at 20hz? Has anyone ever heard of anything crazy happening to someone from the high bass levels inside a car? Like deaths, fecal spills, heart attacks, ear drums being blown, etc.?03 F150 on 24's

Subs:(12)S12L7

Amps:(3)KX2500.1's, MC-2004

Heard of all of the above. But it all still occurs at extreme levels, 120dB and above. Yes you can hear a 20Hz note, but it requires a tramendous amount of power to get an audible/useable sound from the sub.

i have had girls puke, never a guy,,,,my buddy had diareah one day, , i cranked the system and made him poop his pants just as i dropped him off in his driveway haha ( i was nice and didn't do it before going out)2003 Chevy Avalanche,Eclipse CD7000,Morel Elate 5,Adire Extremis,Alpine PDX-4.150, 15" TC-3000, 2 Alpine PDX-1.1000, 470Amp HO Alt.

you made someone crap their pants?  GOOD LORD!  you must have one hell of a system in there forreal

I agree with what ss-installer said about the box being key, but I dont agree with the frequency. I would be tunning the box down far further, some where around the 28hz range. But thats a personal preferance. Also you should be using a subsonic filter when using a ported or vented enclosure, it helps protect the subs and helps prevent wasting power on frequencies that you cant use anyways.double-secret reverse-osmosis speaker-cone-induced high-level interference distortion, Its a killer

Urban legend, man... Episode 25 (Feb 16, 2005) of Mythbusters tried it... Proved scientifically it does not happen. Something like 153dB at frequencies between, like, 5Hz and 20Hz. I cannot remember the numbers exactly, but it has been debunked. Meyersound provided all of the gear, and it was televised, on a respectable network, called The Discovery Channel. Hate to do that to ya, but there ya are...It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Good read. Note that I just said that it requires an extreme amount of power to get a useable tone at sub-sonic frequencies
