Posted August 31, 200718 yr i am wanting to get the most spl i cani order a BL 18 inch subi have a rockford power 10001 mono ampi am having the jb fisher place design my box and i needed to know what the best cuft sizethey said that 8cuft would probably be the best but they said i might want to post on this forum to make sure thats best
August 31, 200718 yr 8 cuft would work well. For a low tuned daily setup Id look to about 33Hz. We normally recommend 12-16 sqin of port per cuft as well.Please let me know if I can help with anything else.Thanks,Scott
