[QUOTE="ancorp, post: 8352435, member: 633405"] You will have to raise your tuning if you plan to use a pair of 12" ports. To tune to 30hz, they would have to be 40" long which I can't imagine fitting. And they'd eat up 5.5 cubes. Leaving you with only 13.8 cubes net, with over 16" of port per cube. Way too much for aeroports. 9-12" per cube is more sensible. I'd do a pair of 10" flared/aero ports. You would likely be louder with four 15s then a pair of 18s. [/QUOTE]
