Help needed..... DD 9512 symetrical enclosure design


Recommended Posts

So Ive just bought a DD 9512 to be installed in a 96 Accord. Im going for a show quality install, with a no nonsense approach to power (1.5k -2.5k for the sub alone)

The problem that i have is that i would really like the sub enclosure to be symetrical. I plan on facing the sub toward the rear seats, so i would need a box design that has a port on each side.

Ive never build an enclosure with more than one slot port...... will it sacrifice performance at all? How do i go about it?

any input is much appreciated.

P.s. i cant have any of you pros build me one because i live in the asshole of the world (New Zealand) and shipping would be mental expensive.

They are better than a slot port without a big ass flare if you ask me, 2.5 cubic feet and 2 6" aeroports it´s a proven kickass box for the 9512, you could get an aeroport on each side...

I'd just do two slot ports. Using a lot of port area with aeros is a pain since you end up needing to buy elbows and such to make the turn inside the box. And you'll probably have to find your own thin-wall PVC to extend the ports longer, since they're only 17" stock. IMO slots are just easier to make work, especially if you want a lot of port or a low tuning.

Yes sir you are right, i didn´t think about that before since i´ve tried those subs in a big ass SUV, 2 6" aeros on a trunk car would be a pain in the ass for this application on a 2.5 c/f box, maybe 2 slots 24SQ each one??
