Box Design questions

The reason I think they can hit 32 Hz is because the site says it, I don't know that much about this that why I am here. I do like the FI-Q 15".

The thing I don't like is all the coloumns.

DUAL 1 | DUAL 2

Fs: 32.4 Hz | 32.1 Hz

Re: 0.7 Ohms/coil | 1.4 Ohms/coil

Qms: 8.52 | 8.61

Qes: .43 | .44

Qts: .41 | .42

Mms: 293g | 299g

Cms: 0.82mm/N | 0.82mm/N

Sd: 810cm^2 | 810cm^2

Vas: 75.6 l | 75.6 l

Spl: 89.6dB 1W/1m | 89.4dB 1W/1m

Bl: 13.9 N/A | 19.65 N/A

Xmax: 28mm

Rms: 1000W

Sealed box: 2-2.6 cuft

Ported box: 2.8-4 cuft @ 28-33Hz

Sub OD: 15.625”

Cut ID: 14.125”

Mounting depth: 8.500”

Displacement: 0.19cuft

I don't know any of that

Well what about the L7, I am looking for a square sub because they are the loudest out of all subs.

Clear your mind of anything you think you know about car audio and start over from scratch with a blank slate.

32hz is simply the free-air resonance of the subwoofer. It is not a strict indicator of how low the sub can play, though it does play some part in the equation, since subs with a lower fs generally play lower tones easier(in the right box).

Well I think I am going to go with eh FI-Q 15", would it be best to get a different amp since the FI has a higher RMS than the L5?

I would get something bigger then a road thunder 2200 yes.

If you want a good deal on a 15" FI Q PM me. I have two for sale in the FS section.

No i didnt mean the road thunder, I mean the Power Accoustic 2000.

It is hit and miss with power accoustik. Which amp do you have(or plan on getting)?

Again sorry for double post, my previous post was not shown yet. Does anyone know by chance what Ohm the FI-Q 15" is? would help to know so I can choose amps correctly.

If you buy new as you stated you would(in the PM) then you can choose the coil setup.

from the FI site you can get a FI 15 D2 or D1 for around $300 shipped with no options. Fully loaded is around $345ish shipped
