Box Design

[revots 10+ year member]

I have a 10" MT, no amp yet but it will be between 1800-2200 rms. I want it top firing and rear ported. It's for a 97 civic and max dimensions would be 42x15x16. Tuned to 32-34 htz.

i have LEAP but i can't figure out how to bend ports. I appreciate any help.

i don't know if it will make it easier but, i have a little room to expand with depth if needed, but would like to keep it to a minimum.

I'll design you a box just give me a second..

Well how about 13" tall by 24" wide by 16inches deep. Port 11.5inches by 2.5" by 24 inches deep.

Thats 2.1 cuft tuned to 33 hz

 

[revots 10+ year member]

that would work but is 28.75" enough port area?

 

[sxpimpin 10+ year member]

That was actually supposed to be a 2. I don't like using really long ports....

Its 23 inches of port. Which is perfectly fine for 2 cuft and one 10.

I used 74inches of port for 9cuft and two memphis mojo 15's and it was insane. No port noice either.

what was supposed to be a 2. port noise is what i'm woried about, would it be ok to open the port up to 3"

i answered my own question about the 2..

 

[sxpimpin 10+ year member]

if the port is 3inches wide the tuning increases to 41hz

 

[revots 10+ year member]

i get that, but not if you lengthen the port. if not 3" than i would at least like 2.5".Thanks for your patients.

Alright.

Here's a revised one to get the 11.5 by 2.5" port..

box= 13" tall 26" wide by 16" deep

port= 11.5" tall by 2.5" wide 28" deep

tuning is 34 hz and the box is still 2.1 cuft due to the added port size

btw Steve Meade did an install with two MT 12's and only used 2 4 inch ports..

That worked out good for the install he did-no port noise
