[QUOTE="dinkaTHEdon, post: 7806220, member: 642741"] Hey, so I purchased 2 American Bass XD-8 subwoofers, and I need help building a box, I listen to rap, hip hop, rock, metal, and D&B. I'm pretty sure a sealed enclosure would be good, but need to know if it will hit the low end notes decently, I'm a SPL head first, SQ 2nd, but I heard these subs bump so I'm pretty sure it will give me the SPL I want even with a sealed enclosure. Enough of this rambling, what I need is both advice, and help on building an enclosure, I had a thread open about needing help deciding, but now I need help with the box, what is the recommended box volume? I tried emailing american bass but I haven't gotten a response from them, and it's been a while since Mobile Dynamics that I forgot the formula's to find the optimum box volume sealed or vented.
