1.5ft^3, 20-25in^2 of port, 35hz tuning.

I know this was a while ago, sorry to bring it back up, but is the 1.5^3 including displacement. So you basically saying just build a 1.5^3 enclosure and it'll be fine? So for 4 build a 6^3 enclosure? When doing port area, do you multiply the 20-25in^2 by 4? So 80-100^2 of port area?

1.5^3 NET, so after sub/port/bracing displacements.

And yes you can multiply port area x4 if going to a 6cube net enclosure. I'd do 96^2 for 6 cubes and I'd tune to 38Hz unless you play a lot of Decaf's lower stuff.

My old wall with HDC's was tuned to 38Hz and played "trunk bang" at 29Hz no problem.

whatever size you make it, just remember as a rule of thumb betwee 12-14^2 of port area per cubic foot

HDC's prefer 16^2 per cube, built a LOT of boxes for HDC's the last 3 years and do 16-20^2 per cube.

Current daily set up is 2 12" SDC's with 20^2 per cube tuned to 42Hz. Sounds very good on old school hip hop and 80's metal...

so if you have a lot of port per cube you can tune higher and still hit the lows good? I know AQ subs like a higher tuning as it is but i've read a lot about box recommendations for these subs and its so over the map it always threw me off

was looking to get 2 12" hdc3s, lots of low music
