[QUOTE="BOOMINGRANDPA, post: 8613894, member: 671921"] i'll assume the cf of box is correct 4.38cf ad is that after sub disp? 11.4 sq in port per cube is a tad small for 2 subs anyway with slot port (u cold throw up pic of box) but port area u need also depends on how much power u have so what amp do u have model and all?, if it's just like a 1k or less u probably ok if's it's a strong amp u probably need bigger port.. if u had done 4.25x12.5" port (which woulda made box little smaller) u woulda had around 13 sq in port per cube better if u have good power.. if u stick better subs in there u probably be ok, if u don't go with too much power.. i doubt anyone has pa subs in wins to model air velocity i just modeled 2 rf p3's in your box with 800rms clamped power (400per sub) probably more than u have.. wins showed tuning around 36hz too, air velocity was low on the p3's (20m/ps) so maybe u ok but idk pa subs.. other subs would be higher especially 1 like mine..
