im putting my 2 in 4 cubic ft tuned to 33hz

 

[PSturmer 10+ year member]

2 cubes @ 32 hz with a single 4'' aero per sub.

mkk now how do i get the certain measuremnet to get 32hz for the port... and how wide should the port be?

 

[Mattd0344 10+ year member]

Do two 4" ports in 4 cubes tuned at 32Hz. Circle ports sound sooo much cleaner IMO....I had my two 12's in 4 cubes at 37Hz..got a little low but probably would've done wayy better at 32Hz

i had mine tuned to 31 hz and they got real loud

ok heres what im workin with, i have 39Wx22Dx16H how many cubic feet is that? also how long should the port depth be to achieve 32hz?

ll those would be the boxes external measurements so externally that equals out to about 7.9ft^3.Now internally (lets not figure port yet) you would have roughly 6.44ft^3 internal.

What kind of port are you wanting to do,slot port,aeroport external ports?

The 12's like 2-2.5ft^3 internal (per sub) after port and woofer displacement,tune anywhere from 32-38 Hz (I like 35Hz tuning).

For two 12" type r's I'd do roughly 4-5ft^3 internal after port and woofer displacements.

Checkout this page for free box plans (anything 4ft^3 @ 32hz-35hz to 5ft^3 @ 32 hz.

im going to have them i a slot ported and what is an external port mean? and i want it to be at 32hz

 

[Bassphreak 10+ year member]

external port is a port outside the box...pick anyone of those box plans that are tuned to 32Hz....for two subs you want a box that'll be 4-5ft^3 internal after port and woofer displacement.

yep. 4.5 cubes tuned to 32hz is the best i've heard them in. loud and low. done 10 or so boxes for type R's. that is what i'd recommend.

thank you, also if i only want one port on the side, would i have to have a like divider in the middle between the subs? and how would i calucate the internal box after port and woofer displacement..

no if you put port on one side do not put a divider.

1.75 per @ 32-35hz

Even 1.5 will work....dont need a big box to sound good

Ive had both, and 1.5 per 4 subs now

how much pwr were u running daily to each sub?

500.1 @ .5 ohm

ummm...maybe 900ish

I ran 2 of them in 1.75 per with 500.1 @ 1ohm also
