How many cubes?

[jolly_26 10+ year member]

Daily driver box for 2 12s, they have a 14mm Xmax, will be running at 350-400 watts a piece. I was thinking 4 cubes, 48 square inches of port and a 30Hz tuning, or is this over the top? The car it's going in is a daily driven sedan, but I want this box to hit really hard and really low, and every time I build a bigger box I seem to get better results.

Would definitely be happy to downsize if it will yield better results, just trying to get the best; note that I want this setup to have clear and well defined bass as well as just loud, so that's why I am not so sure about with going this big.

Any thoughts?

Box volume depends on vas, fs and qts parameters. What kind of subs are they? Or could you post tsp's?

Fs: 37.2Hz

Vas: 1.19

Qts: 0.81

and it turns out the Xmax is actually 11.5mm

Cheers, I'm new to box building, trying to learn, I'll do some research on how those affect box size myself, but if you could help that would be ideal
