View Full Version : Check my box

03-01-2006, 05:37 PM
I have a design I would like someone to double check for me. It is 2 cubic ft after sub and port displacement, with a 4" PVC pipe 11"long for a port. This is for a pair of tens. My math gives me a tuning of 30 hz. Please correct me if I'm wrong. This is going in the back of a wagon, so will I have alot of port noise? Any questions? Also where is the best place to vent the port for SQ?

First post very educational forum, thanks.

That might not be enough port area for 2 10's...try going with 2 4" diameter ports or even a 6" Aeroport.

I am probably wrong but doesn't a larger diameter port make tuning higher?

Not enough port,try usin 2 ports,and ur math is wrong ,4" x11" would tune u around 35 hz

So then, 2 4" ports at what length? Also where should they be placed?

any where u can fit them,but there one proplem,cuz the box is so small.the 2 ports need to be about 35 inched long....what kinda subs do u have and how much room do have to play with,u might just be better sealing them

From what I am getting, I think I am going to stay sealed and just build a new box. Thanks for your help.
