Anyone want to design a box for me?

[5.4SPL 0]

I've got two of these but temporarily I want to see what one can do, I'll be running it off of 900wrms.

Anyone want to design me a nice efficient box, tuned anywhere from 27-32 hz? Sub will have to be facing forward, aero ports preferred, 6" PVC pipe is what I'd like to use.

Max dimensions (to keep it under window line) would be 54" length x 22" height x 15" depth.

Efficient? Build it larger than recommended. Try out 9^3ft.

Your one 6" port might be big enough to minimize port noise. For a 27hz tuning, cut the port to 7.22"

Great thanks, How about two 6" ports?

Probably be better to go with 2 4" ports instead of 2 6".

If you go with 2 4", use flared ports and cut them at 8.40" each.

This will give you a 9^3ft box tuned at 27hz.

With 900 watts and a 9 cu ft enclosure two 4" ports isn't enough...I'd go with two 6" round ports.

Thanks for your help guys, 9 cu/ft is doable but I'd prefer a tad bit smaller, I'd like to know necessary (not flared, PVC) port lengths for these sizes:

7 cu/ft @ 30 hz

8 cu/ft @ 30 hz
