jbass1 Posted August 30, 2016 Report Share Posted August 30, 2016 hey everyone, i have a dd 9500 18 special, in a 6.5 cubic box. Slot port tuned to 62 htz (ish) was looking at going with a psychoport maybe like 10 or 12 inch. Has anyone used these? Is there much of a difference (spl) wise. I do about 153.2 with the current set up using 2 DD M2Bs, Link to comment Share on other sites More sharing options...
fecupe2001 Posted August 30, 2016 Report Share Posted August 30, 2016 yes those ports are awesome!I tried single 12" myself and didn´t work that well, there´s a point where too much port area kills your score, IMO, single 18" sub gets louder on 3 6" aeros or a single 10" on almost every car out there , what car do you have? your current score is great btw!
