john253a Posted July 28, 2012 Report Share Posted July 28, 2012 with out knowing all the info im aussimg there 15" this is what you built this is probley closer to what you have Idd say to start port is too small, and without knowing anything about how you built it, or bracing, your tuning is probably higher then 36hz, so that would explain why, post some more info on what you have, power and anything to do with box and bracing (pic never hurt) and will see if we can help some more, but im assuming your tune is probably closer to 37-38hz Quote Link to comment Share on other sites More sharing options...
bdog Posted July 28, 2012 Author Report Share Posted July 28, 2012 (edited) no bracing yet but im glassing in a 2x4 dead center top to bottom . its running a saz-2500 on 4 sa-15's and yes it feels like im tuned to 40ish because 45ish is the loudest and most intense and the vehicles RF is 41 Edited July 28, 2012 by bdog Quote REP Link to comment Share on other sites More sharing options...
bdog Posted July 28, 2012 Author Report Share Posted July 28, 2012 and yes your torries is bang on what i did Quote REP Link to comment Share on other sites More sharing options...
john253a Posted July 28, 2012 Report Share Posted July 28, 2012 I see you have a removeable port, you could just build another longer port, idd try to do 2 common walls this is what i would do you can go upto half the port width from the back wall, but at 10w x23.25d you have 32hz or 9.5w x 23.75d 30._ hz just dont go under 9.5w Quote Link to comment Share on other sites More sharing options...
bdog Posted July 30, 2012 Author Report Share Posted July 30, 2012 Well it's not the tuning I just made a 30hz port for it and didn't make much of a difference if any . Could it be box flex and roof flex ? Quote REP Link to comment Share on other sites More sharing options...
