Default Box for JL audio 12W6

Here's a design on a JL audio 12w6. I have it tuned at 32 hz and ports 9.375 x 27 long. I need opinions on this. Please leave a feed back

Although the ports make great handles, the box will be very heavy.

But overall it's a good design, right? Gonna be used in SPL competitions.

a little brace between the back of the box and the first pad of the port.
you dont want your port to flex.
maybe a broomstik between the sides for pannelflex sideways.

32Hz is too high to tune for SPL, it takes 4x the power to hit 100dB @ 32Hz then it would at 64Hz-so tuning higher will yield higher SPL score off the same sub/amp.

I'd remove the section of vent from the back inside of the box, increasing box volume and shortening the port to raise the tuning and then have a "music port" which I could screw to the face of the box at the bottom to allow the enclosure to be tuned for music when not competing.

Have you actually bought these subs?

No, it's an idea for a friend. He's buying two of subs when he gets payed and I just want to make his box a good SQ box...but at the same time a SPL box. He owns a van....so any type of sub sounds beasty.

I just thought that at 32hz...it'd be good.

-To Baron, I got 4 of the 10 in Audiobahn in my trunk. lol. I shattered my window when I turnt the gain up to 2.0 volts =((((

SQ and SPL are two different ends of the audio spectrum, it's like saying I want a lightweight sports car that can also pull a plough over my 1000acre farm.

For music tune a little highter-normally around 36Hz is recommended. If he is going to compete the he will need a different box.

RE the audiobahn-lol!
