does a bigger port area pick up more bass?

Large ports are peakier around your tuning whereas smaller ports have flatter responses

looking at dif box not getting bass outta box in have now its 10 cube per chamber looking at 15 cube should that help?

What subs & how much power?

01-20-2012, 11:25 PM
type r 12's right now 1000 rms but thinkn more power since i not getting sound i want

01-20-2012, 11:27 PM
Those type r's will handle 1500w no problem. And I hope that when you say 10 cubes that is a typo. Do you mean 1 cube?

01-20-2012, 11:27 PM
subs r 600 rms so i not wanting to go that much more power hoping box will help they in custom box built to specs but not liking the sound it should b hitting harder

sorry 10 inch of port per chamber **** i cant type

sorry 10 inch of port per cube

Ah alright. 10 per cube is pretty small, usually I try to do at least 12. And those subs are rated at 600rms but can take more as long as the power is clean and you aren't stupid about it. I would bump your port area up to 13-14 that should give you a good amount of extra output. What space and tuning do they have?

right now they tuned at 33 but new box i lookin at is 34 i think

double 07

his current box is 1.5 per sub net I believe......we were discussing an enclosure closer to 2 cubes per sub......with roughly 14-15 inches of port per cube

If you are capable of building your own boxes, I would do something like 4 - 4.5 cubes @ 34-35 with 13-14 in^2 of port per cube. If you don't listen to many lows, raising up your tuning a bit will give you a lot more output.

EDIT: sounds like you are already taken care of, good luck!

i like the lows

33"w x 24"d x 16"h........with a port that is 14.5"h x 4.5"w x 32"d.........It will net you a little less than 2 cubes per sub with a 33hz tune and 15 inches of port per cube thats the box i lookin at

Not a horrible enclosure idea. If you can go larger I would though.

Also make sure you round over the port edges and put at least a 45 in the L of the port and try and make that 45 large enough to keep the width of the port correct through the bend.
