Here is a suggestion, power: to subs rated, amp subsonic filter to 28Hz, minimum port clearance 4 1/4", figure is just an assembly guide:

Sorry forgot my password so logged in on fb. So what if I tuned to 32hz I'm looking for as much sol as possible

[Joe X]

I take you said spl, in that case 34Hz would be better. 32Hz would be to reach lower notes.
