Hey man loving the build so far! ive got a similar build going on atm with 3 815s in a wall.

I was curious how much air volume you are giving those subs and tuning frequency? your box and port just looks small in pics compared to mine haha

Hi! Box is 400 litres minus port. Port area is 1200cm2, 24x50cm. Tuning is 33-34Hz. I'm now working on smaller port, 30hz tuning and 850cm2 area

Cool man, no troubles with port noise or anything?

Your getting an awesome score @32 hz!

Im going to be giving each sub about 145 litres each for a box of 434L after displacement with 29 hz tuning port 71.5 x 21.6 , 1,544cm2

Thats 5.12 cbf per sub, 15.32cbf box and 239 square inch port for the americans reading this haha

No problems so far, port is now 1000cm2 (50x20cm) and tuning 30Hz. That spl meter is 4SPL, mine shows 0,5-1dB less than Termlab http://4spl.eu
