Cliffs: What length aero (3" diameter) to tune to 40hz?
Okay. So I received the DD 1508 that I bought from blackbonnie today... Not much you can say about these things besides beasty mother****er. On to my question.
My box will be 1 cube after port/sub displacement. I have a 3" aeroport and have never used an aeroport before, therefore I have absolutely no freaking clue on length tuning.... DD's site recommends "15.0 sq" vent x 18" long" for a tuning of 40 hz.
I'm assuming that since when using aero's you dont have as much area as a slot port, the length is the same way? Or do I just need an 18" long aero for tuning of 40 hz?
BTW I would like to also have a 2nd aero I can put in to tune it to 32 hz. Since 40 wont cut it daily, but I would like to get it metered and see what it can do in my truck.... I just wanna see what this thing CAN sound like on music (I have my 2 re se's for daily )
