I'm finally able to build a new sub and I think I've got a pretty good idea of what I'm going to do. Like the title says, I'm using the Dayton RSHF 10" sub with the BASH 300W plate amp. Using WinISD I'm planning on a 2-2.5 cubic ft box tuned somewhere in the 20s. The problem I'm seeing is that the is a ~3db peak that starts at 40htz and peaks at 30htz and drops off rapidly after that. I don't want to go bigger than 2.5 cubic ft if I can but I can't seem to get a flat response. What do you suggest I do to knock that peak down? Can I modify the bass boost on the BASH to compensate? Also, I plan on using the precision 4" port.

I'm shooting for building this weekend if I can get a design I'm comfortable with.

TIA

Thanks for upgrading to VB PE. I like it.
