question about port area

[schrummy 10+ year member]

i know for spl more port is better for spl but i only will be giving the subs about 2000 watts of power. the subs will be 2 12s and the most i can give for port is about 120 inches^2. but i think that is too much. what do the pros think.

Whats the air space and tuning frequency?

 

[schrummy 10+ year member]

the net cubic ft would be 7.75ft^3 at 55hz

wow @ 55hz tuning....

I wouldn't do more than 110-115 sq inches at the max...

 

[schrummy 10+ year member]

what about 45 or 40

Well first of all for SPL you want to tune a little higher, 55hz is more SQ oriented IMO

In MOST cases, this is true. But a lot of big numbers have been done at higher frequencies... it all depends on the driver, the box, and the application, really. There's too many factors for a definitive 'yes' or 'no.'

I've never designed a box

anything close to that.

I'm no pro though.

 

[schrummy 10+ year member]

well i have never built a box with a tunning above 40hz so thats why im asking.

Reread my post, and I'll get you an application to be on the retard ballot

I have a competition box tuned to 55 and i wouldnt call it a SQ box, about 90 sq inches of port.. Very loud, but i would consider that a good SPL tuning for daily if you were to do it. For daily beating, i'd prefer tuning to 35 in a car that'll peak in the mid 40s.

Is there no sense of obvious sarcasm outside the lounge?
