Frank H Posted September 14, 2015 Author Report Share Posted September 14, 2015 I did 2.7 cubes for an x12 rev 2 with 15 sq inches of port tuned to 27... Works magic 15 sq inches? That seems very small. But if it works, it works :thumbsup: Quote Scion xBSinger 275Big 3 OFC 1/0Kenwood ddx492Alpine 4ch f600 - Alpine components SoundQubed 4500 - Sundown Audio X12 Link to comment Share on other sites More sharing options...
Frank H Posted September 19, 2015 Author Report Share Posted September 19, 2015 I can't see their box/cut sheet or whatever, but I know that woofer like 2.25-2.5cf. So their recommendation is correct and I assume the cut sheet is off. Build to to 2.25-2.5cf net @ 28-30hz. What would you recommend the port area be?
