SPL Blazer Posted July 25, 2011 Report Posted July 25, 2011 The 45hz tone and higher started to drop off. Should I cut an inch or 2 off port to c if peak freq goes up and gets louder? Did you use a friends TL or was this at a comp? If this is a comp box then yeah, you might want to alter the tuning frequency closer to the resonant freq of the vehicle, if this is a daily box then you may want to leave it alone. Depends on your goal with this system. Quote 2001 Blazer ~ (2) 10" DC lvl 4's, Orion 2500d 148.9db 2005 Astro ~ (2) 18" DC XL's, Atomic 5000.1 153.9 db New England SPL NESPL - YouTube
slow240sx Posted July 25, 2011 Author Report Posted July 25, 2011 i got a removable port. The daily port peaked at 148.1@33 hz. I think ill leave that alone for now cause it sounds good to me. I put in the spl port i made and it peaked 150.3 at 44hz. I dont mind tweaking this port and ill prolly try to raise tuning on it and try to c what happens. There was a comp yeasterday and the guy running it let me take the meter and laptop home to mess around with it today. I did all tests with car running and sealed up with the meter same spot as they do at the shows Quote 99 GMC Suburban 2 Death Penalty 21" 2 Crescendo BC2000 Boston GT-42 Amp 6 Selenium 6w4p 4 Crescendo tweets Hi output cs144 alt Audiocontrol Epic-160 Pioneer DVD head unit
