Dillan Turvold Posted June 23, 2012 Report Share Posted June 23, 2012 Where should I tune to and where should I fire the port/s for SQ? 2 12" kenwoods 400wrms, recommended 2 cu.ft. ported @ 34hz I'm looking for a smooth rolling design that will handle 34~50hz without too much peaking, just having a lot of trouble designing my own I've tried a few different box designs, with slot ports, pvc ports etc tuned at 30hz, 34hz, 40hz, can't seem to find a really good SQ box though, all the boxes were over 1.7 cu.ft., they all peaked somewhere either low or high, the one with pvc ports was 2 cu.ft. but the pvc ports are only 3". the box I have currently is the 2 cu.ft. 3" pvc ported @ 30hz, it really peaks at the low end and doesn't produce jack shit for high end bass, could I just get larger pvc pipe and tune higher to fix the problem? I have the pvc ports to the side and the subs facing the front in my trunk, here's a pic: 15" H x 34" W x 18" D Building a new box is not a problem ofc, but I wanted to check here to see what designs you might have for me b4 I do Quote Link to comment Share on other sites More sharing options...

White Lightning Posted June 23, 2012 Report Share Posted June 23, 2012 I will post a scoresheet after this Scrapin the Coast show to kind of explain why we set it up that way ...

White Lightning Posted June 23, 2012 Report Share Posted June 23, 2012 In Sound Quality, music should sound well balanced ... Nothing should overpower the other ... Components, subs, etc ... Not sure why you would want a (true) sound quality enclosure to be demanding on the higher frequiencies similar to a spl (ground pounder) build ...

I can't afford to do the kind of SQ build I want to do, so instead of being able to have a strong low end and a strong midbass range, I'm trying to meet somewhere in the middle with the subs, though I might just revert back to sealed Idk yet.. -edited cuz i'm tired atm Edited June 23, 2012 by Dillan Turvold Quote Link to comment Share on other sites More sharing options...
Dillan Turvold Posted June 23, 2012 Author Report Share Posted June 23, 2012 think I should increase the port length to ~14" (tuned @24hz)? Quote Link to comment Share on other sites More sharing options...
