dwright27 Posted June 5, 2011 Report Share Posted June 5, 2011 Whatevers loudest, maybe 5 - 10 hz above your peak. 5 - 10 below your peak. What's your ratio? Looks like your ported chamber is hella small. I havent done an SpL 4th order yet. 2006 F-150 4 DC XL M2 18's Walled Daily Driver XS Power 4 DC 3.5kw Team DC Team S.P.L.

TheyDontWantMusic Posted June 22, 2011 Author Report Share Posted June 22, 2011 the box had been designed to have a peak at 50Hz... it has the opposite.. why? Link to comment Share on other sites More sharing options...
TheyDontWantMusic Posted July 2, 2011 Author Report Share Posted July 2, 2011 we run rules here that put the TL sensor on the dash, "db drag" location, but allow you to open other parts of the car... so I did, the trunk, rear windows, and drivers side window. plus sitting on the roof at the edge of the sunroof gained 1dB!

TheyDontWantMusic Posted July 2, 2011 Author Report Share Posted July 2, 2011 146 with everything open?? god damn!!! that should be way higher with only the driver´s door open! nope, its quieter. the only window that didn't make it louder having it opened, was the passenger side front window, near the TL sensor..

fecupe2001 Posted July 2, 2011 Report Share Posted July 2, 2011 for real?? damn, maybe because it´s a trunk car?? i dunno, generally speaking, the cars i built are louder with everything closed except for the driver´s door I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.
