My 4" from them was 18" long too

so knowone knows what the dimpled ones are

Supposed to be even better airflow then the regulars...like the dimples on a golf ball

ok now my last question is. for the frequency i want i need a 4" port thats 11.75" long. would there be a differance if i did 2 4" ports 5 7/8 long?

[SLAYER1805]

I just looked at them on their website and I can't really make out the advantages of the dimples because I would think a smooth surface would be better for the airflow. But then again golfballs are dimpled for better air flow. And for your last question you can't do that it has to be one port, it throws everything off and that would bring you up to 69-70 hz

[ToNasty]

you do realize thats the port length split into 2 right. it would be the same port area

[SLAYER1805]

I ran those specs through the PSP calculator and got 69-70 hz, I would try it on torres but I don't have on the computer I'm using

[ToNasty]

then a single port it is

ok would there be a differance in using a 6" port (obviously i would take that into consideration with port lenght)
