Cory2G Posted November 3, 2022 Report Share Posted November 3, 2022 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 Link to comment Share on other sites More sharing options...
Cashdollar2009 Posted November 3, 2022 Report Share Posted November 3, 2022 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 1997 Chevrolet Cavalier Two 12" DC Audio XL M2'sCrescendo Audio BC5500d Current Scores: 150+ out the Trunk On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free.

Cashdollar2009 Posted November 3, 2022 Report Share Posted November 3, 2022 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. 1997 Chevrolet Cavalier Two 12" DC Audio XL M2'sCrescendo Audio BC5500d Current Scores: 150+ out the Trunk On 6/30/2011 at 1:11 AM, 'Ray' said: Acoustical energy is free.

Cory2G Posted November 3, 2022 Author Report Share Posted November 3, 2022 Thanks for the feedback. Will be running a SAE 2000D I couldn't pull up SA enclosure recommendation as I don't have access to my desktop. So that's good to know Link to comment Share on other sites More sharing options...
Cory2G Posted November 3, 2022 Author Report Share Posted November 3, 2022 So I could do both subs on one baffle? Link to comment Share on other sites More sharing options...

Joe X Posted November 5, 2022 Report Share Posted November 5, 2022 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. Link to comment Share on other sites More sharing options...
Cory2G Posted November 7, 2022 Author Report Share Posted November 7, 2022 Thanks Joe good info! What are your thoughts on both subs on same baffle? It seems like a lot of people do it? Link to comment Share on other sites More sharing options...
Joe X Posted November 7, 2022 Report Share Posted November 7, 2022 I would recommend you the shared port design: Link to comment Share on other sites More sharing options...
