Recommended Posts

First off new to the forum. Sure yall see this sort of question alot.

Hopefully I can get some good feedback. 

I got a pair of SA E15 V.4's I have designed an enclosure for but would like if someone could give any advice as I have no access to a better enclosure calculator. 

Sorry in advance for the scribblage

Hey Cory, welcome!

 

Is there a reason why you are drawing it up as two separate chambers/boxes instead of a shared chamber for both subs?

 

Also, what amplifier are you running?

 

Either way, I am coming up with the following based on your dimensions pictured:

Net Volume: 3.72 ft^2

Tuning Frequency: 39.76 Hz

Port Area: 64.75 in^2

If you were set on running two separate chambers, the following puts you right around Sundown's suggested numbers:

20H x 20W x 27D

Port Dimensions: 18.5H x 2.75W x 30D

Net Volume: 3.27ft^3

Tuning Frequency: 34.19Hz (The tuning frequency you requested above, Sundown suggests 32Hz tuning for these E15's)

Port Area: 50.88in^2

 

If you built two of these and joined them together as it looks like you were trying to do above, you'd only need 40W x 27D for the top and bottom pieces.

Avalanche are subs / port forward box placed at the mid gate location, so you are fine.

 

Box specs per driver is 3.25 net @32Hz with 52 square inches of port area so since there are two subs your box specs should be:

 

 6.5 cubic feet net @32Hz with 104 square inches of port area.

 

Ideally you want to seal off the trunk for better results.

 

So let me know any questions.
