JustinT Posted June 27, 2009 Report Share Posted June 27, 2009 Well my mojos are starting to suck...blew a coil actually. And now its time to upgrade to BTLs I'm stuck between 2 15s or 2 18s Here is the scenario: The ports will be outside the box. I am going to use these ports... Deal Breaker for 15s: the only practical option is to use 1 of those ports for 8 cubes Fi recommends 12 - 16 square inches of port per cube 8cuft x 12 = 96 8cuft x 16 = 144 So about 96-144 sq inches recommended. that port is only 70 sq in. Would that be a problem? Deal Breaker for 18s: The only problem for the 18s (using 2 of these ports) is that the box would simply be too long to conventionally mount the ports outside the box... So to still be able to show off those peerrrty port flares, I was going to mount half of them inside the box and the other halves outside the box with the joiner PVC glued into the side of the box. My problem with this is that the inside port flare is going to be about 12 inches inside the box rather than flush with the wood like the 15s would be. Is this going to pose a problem with the function of the ports? So...15s or 18s?

EricR Posted June 27, 2009 Report Share Posted June 27, 2009 why not 3 15's... sexy ass ports too. why is one smaller than the other though Quote i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?
