jonathancullen89 Posted January 31, 2008 Report Share Posted January 31, 2008 for spl tune high like around 40-45hz. for a more sq system you picked a bad sub lol, around 32hz has a better roll off and should sound nicer. there are alot of things that will change this though, box size, port size. id go to re and make the recommended box for it if possible.

emperorjj1 Posted February 3, 2008 Report Share Posted February 3, 2008 seen mts in boxes from 35-45 and 45 was the loudest. If you listen to rock or techno then id say tune lower but if your mainly into rap 40-45 is best Quote J.

If you listen to rock or techno then id say tune lower but if your mainly into rap 40-45 is best youve got it completely backwards. If you listen to mostly rap, tune it lower (33-38). If you listen to mostly rock and techno, tune it higher (40-45) Quote Michael Hughes = 6X SPL World Champion - Loudest on the planet in db Drag, USACi, and IASCA.

fourlug Posted February 7, 2008 Report Share Posted February 7, 2008 youve got it completely backwards. If you listen to mostly rap, tune it lower (33-38). If you listen to mostly rock and techno, tune it higher (40-45) Gotta agree with the big boys here, personally with a ported box I go with 31 hz.
