ok i already have subs built into my towers which are plenty loud but as you can tell by the graph below they drop off really bad around and under 30 hertz.

what would you guy recommend?

me build my own?
or recommend me a sub?

here is what i am thinking a getting a tc sounds 2000-15" sub and one plate amp 500 watts rms (only problem i see with this is if i screw up somehow on the box its gonna be peaky which i dont want)

Build your own. HT subs are normally tuned much lower than car audio subs. I'm running 4 Tempests and the box is tuned to 18Hz. They get PLENTY low and measured 129dB @31.5Hz at 1 meter. Running off a measly 800watts total....

getting good output below 30 is tricky, not sure id bother, not much recorded below 30 on anything. couple diosaur stomps and a helicopter now and then but why invest $800 to hear that?

thats another thing i was thinking also. its not that i want movies to be louder but will it be worth investing more for something i might not hear often?

transmission line would do it easily, but its a pretty long line!!!

my two 12inch Pioneer subs are doing 123dB +-3dB from 30 - 80Hz, in my listening position (about 2 meters from the subs) however, they were louder in a solid brick house.

what was that response even measured with though?

what power is that with?

4 or more 15" Fi Qs and build an IB manifold for them, then get a lot of power :)

Have you tried positioning the speakers differently in your room?
Placement can have a big effect on overall sound.

i used to think fi wasnt made for ht but after some more looking into they look like an awesome sub to play with. i wish i had two 15"s or at least one so i can write a whole review on all the forums i visit :) i bet they would slam in my room ;) :yumyum:

I might have something in my stash that will work really well. Think LMS 4000 but in a 15. I know they stopped making them so specs might be hard to find.
Can you get a larger amp, maybe around 800-1000W ?
These linear drivers have incredible low end, great for LFE.

What ever you get make sure that you are not going to underpower it!!!! That is one of the biggest mistakes, for a driver to slam on extremely low frequencies it needs a good amount of power!!!!

Depending on how much low end you want, one 15" in a proper box would be enough. :fyi:

BEStereo.com is my website.
I found a woofer that will work great for your application.
Its basically a LMS4000 but it has an eclipse cone.
