rambronco Posted February 11, 2015 Report Share Posted February 11, 2015 Did I read that right and you have 23 square inches of port for a 1.47 cube gross box? That's a shit ton of port area for that small a box IMHO. For comparison, that's a smaller box and more port area than my SA12 is in. What sub are you building for, and what is the recommended box size/port size from the manufacturer? I actually bought a prefab box for my 2 Sundown SD10's (ya, ya, I know, this isn't the place for prefab lol) was just something to get me by. I didn't measure it at the shop just looked for something that didn't have a 4 inch long port lol. When I got home and measured it I was shocked and skeptical at the same time because of the amount of port area and to be perfectly honest, the box gets down. 22 sq in of actual port approx. 25sq in per cu ft., granted the box is fairly large because of the amount of port area, but I don't think i'd change it other than a little lower tune. 01 Chevy Silverado X-cab 2 Sundown Z18v4 walled on 2 Lanzar Opti 7k's strapped at 1/2ohm = each amp wired to 1/4ohm. Havent checked impedence rise so not sure what they are actually seeing. 6 group 31AGM's. 2-Eclipse 34230's each one running 2 Eminence 6.5" Beta 6A. These are beastly mids rated at 350w program power. I was skeptical but the eclipse amps are 370w x 2 and when there was 4 mids on 1 amp I could push it into thermal protect within a song so added the 2nd amp. Eclipse 4212 running 4 CT sounds Meso tweeters. and 2 DLS ultimate tweeters up high to raise the soundstage. 96' Ford F350 4wd 4d long bed 7.3 diesel with 91k miles. Will be the sound quality rig if I can ever find the time. Link to comment Share on other sites More sharing options...
