Lowest and/or loudest subwoofer system?

Question

To give you an example, the Bag End Infrasub-18 can go down to 8 Hz at -3dB.

Also, at the 2000 CES there were a couple of subs that stood out:

Tyler Acoustics' Titantic 23" powered subwoofer

(You can see a glimpse of it on the far right of the picture...)

Wilson Audio's XS dual-18" tower subwoofer system.

Simply phenomenal!

What systems do you know of or felt (since it would be below the ear's audibility)?

Thank you for your answer, "enochiansorcerer ", nice (arguable as to some of the specifics) teaching point... However, I have already touched on your point about what frequencies you can hear and those that can only be "felt". How about sticking to the topic for conversation and answering the question at hand that I have asked here instead? I would appreciate that even more. ;-)

Answer 1

Have you ever heard of the "Eminent Technology Model 17"
Frequency response 1Hz to 30Hz +/- 4dB
Maximum acoustic output >110dB between 1 and 30Hz.
Price $12,900 each, not including amplifier or crossover

Answer 2

Actually the human ear can only register 20hz, frequencies lower then this occur as vibration. The best is determined by what application needs to be served, for music you don't want speakers with a frequency responce below 20hz, it's just gonna make vibration and distort the low-end crispness of the punch. But for entertainment scenerios the lower the better because vibration adds ambience. Also you might want to check out The BBE Sonic Maximizer sub-harmonic proccesor.

Answer 3

Look into the larger Velodyne speakers. You must consider more than just the low frequency capability; distortion is very important. Velodyne uses a voice-coil feedback system to minimize distortion. The problem with distortion at low frequencies is that it doesn't always sound bad. For example, a 10Hz tone with distortion will also produce a 20Hz and 40Hz tones. Your ear will be "fooled" into hearing the low note as louder than it really is. So you can't depend on your ear to evaluate distortion, and if you can't measure it yourself you will have to depend on the manufacturer's specs.

Answer 4

to be honest, i dont know about any of those. but i do know that you cant hear anything under 20hz, so to get a sub that goes lower then that, is kinda pointless. unless you wat to feel the bass. then its cool, but if you have vents in your room, there going to rattle like crazy. i have 2 subs. my first buy was a Klipsch rw-12. i loved it, and it sounds great. but i wanted more bass. so i bought a sunfire dual 10". you may thinking its only a 10" but let me tell you, its 2700 watts of crazyness. truely a get sub. and the thing is 60 pounds, so you know the sub magnets are huge. heres a link, and i hope this helps.

Answer 5

appears like its getting too a lot on the enter part and reducing out. possibly it truly is on and off because the amp is overheating and closing right down to guard itself. as quickly because it cools, it activates back surely to overheat back and bypass by the total cycle. possibly matching the authentic unit and the amp with a transformer might want to help.
