3.75 CUFT too much for a single 12" X/Zv4?

[S1R-BLUNTZWORTH 10+ year member]

Is 3.75 CUFT too much for a single 12" X/Zv4? Technically it would be 3.83 CUFT. The box would have a slot port that is 4" wide, 25" long, accounting for 0.83 CUFT of space, reducing box volume to an even 3.0 CUFT. Port area is 60 SQIN, resulting in 15 SQIN per CUFT of box volume. It would be tuned to 35 hz. Too big? Am I good on the port?

Pushing it.

Your net volume appears to be around 3 cubes, so 60in of port = 20 in/cube of port, which is too much unless you're using low power. Tuning seems kind of high for an X/Zv4, too.

Thanks, was basing square inches of port per cubic foot off of gross box volume, didnt know it was based off net. However i will be running a relatively low 1400 watts to the X/Zv4.

Having a large box and large(ish) port is fine on that power, it'll dig lower and have more output. I'd shoot for around 15-16 sq in/cube.

Just for reference, I would use Torres box calculator up get a general idea about the box you're going to build.
