yes very much so haha it moved my LMT's the full 50mm off 800 watts per sub...

depends on where ur SSF is set at, most people have such high tuned box's and the SSF is usually around 30-35hz that ur subs probably wouldnt even see the 10hz frequency from the amp. Ur amp has to be able to reproduce the frequency as well. Like his IA's can amplifiy from 10-350hz.

yea i had my SSF up pretty high and they still moved like none other lol

well it would also depend on the slope of the filter i guess. duno what it is for the IA's

ive sen all the way down to 4hz on 20 12" subs at mobile dynamics when i was there. unreal shit. we also played like 7500 hz on em.

how come on that hoods run down song i could hear all the levels off of 2 10" w0 in a regular cab truck(my first set up)

Keep in mind that the frequency response of an amplifier doesn't mean that outside of that range the amplifier ceases to operate...only that the response is no longer flat and has began to rolloff.

If by "all the levels" you mean all of the frequencies.....it's because you were hearing the harmonic distortion the subs were producing rather than the actual fundamental frequency.

I didnt know that, So it works like a X-over point?

kind of figured something else i just always wondered

You could think of it in somewhat the same sense, in that the frequency response is normally rated by when the response has rolled off by some rate, such as -1db or -3db.

you will hear notes lower than what the x-over is set at due to box design and transfer function.

Try playing:

Do or Die- Chain of Command

You'll notice at certain frequencies things are shaking but you cant really hear it.

it's tough to determine what you are actually hearing. subs are moving air which moves other stuff in the area, creating noise. harmonics exist in everything audible. sealed enclosures typically do better with lower frequencies as they have the flattest roll-off - unless you're tuning to 20-25Hz.

My buddy and I have played around with

http://www.rexroatsound.com/rexmpt-48.html

these are the ultimate point-source array speakers.

while it's not a typical bass track (and i sound gay bringing it up); Sleep to Dream by Fiona Apple extends well below 20 Hz and makes a nice test track to see if you're distorting (female vocals + low bass).
