[QUOTE="Doxquzme, post: 8851907, member: 689267"] I used BASS Box Pro. It’s what parts express uses on most all their woofer spec recommends. I didn’t build the box phisically that is. I also modeled the box you provided as well. Going off the NET 1.6cu ft of your box - two, 4” ports 23.5” long or one 6” port 25.68” long. The single 6” vent has slightly less vent noise, both options are pretty good. using the box you proivided and the results are almost the same, even looks a little better. So, the box that you initlally posted and two of the Kicker L7's, 8" woofers. [ATTACH type="full" alt="1691632473441.png"]51197[/ATTACH][ATTACH type="full" alt="1691632497714.png"]51198[/ATTACH] [ATTACH type="full" alt="1691632636288.png"]51200[/ATTACH] don;t worry about the secondary rise in the graph, it's not a factor, not relevant. For the others you listed, Name: CVX12 (2 or 4 ohm) Type: Standard one-way driver (12" Sub) Company: Kicker BASS Box pro didn;t like the CVX 2's a ported box, stronly suggested a sealed box, and a big one at that! At 31Hz, wanted a 6 cubic foot box, which looked pretty good, 11cu ft sealed box looked very flat dwon to 31Hz. The response in any of the ported boxes were very peakey, somtimes as much as 9db, very undesirable in my book. This was 2 of the CVX 12's in a 6cu ft box, 6" port 40" long!
