Enclosure Design Request - 3 SA 12's

[nunyagd]

Looking for some enclosure design help for 3 SA 12's ported and tuned to 35 - 37hz range. I can give them more than rated power (700 - 800 per woofer). Listen to everything. Mainly want a good balance of SQ and SPL.

Space I've got to work with:

• 48" width
• 17.5" height
• Depth is variable but no more than 21"

This will be in a trunk and hoping to fire port and subs backward.

Thanks in advance for any suggestions.

where's the port area?

Here's one suggestion,you will want to make sure it will fit through the trunk opening before you build it.

6cuft net @ 36Hz

Gunnem------> 16x5.5=88 sq in

Thanks man, appreciate it.

Any others? Would be awesome if someone could throw up on of those visual designs a la JoeX / Sketchup.

Here is a second suggestion, modified to OP's request to 48W, free airspace in front of the port is 5", subsonic filter to 28Hz, power to 3K :

This is awesome, thanks!

I know 48" width will fit because I mocked it up out of cardboard. I really want it to be that width to fit tightly in the right spot. If I want to adjust JoeX's design to be 48" wide, can I take that away from the depth? If I do that how do i resize the port.

Thanks!!!

Changed it to 48W wondering what's the vehicle with a trunk opening of 48W ?
