nickers Posted May 24, 2011 Report Share Posted May 24, 2011 (edited) IN that SPL gains thread (SPL GAINs ) the guy said, and showed on termlab that he lost output by rounding the corners in his box, but certain corners gained. Can someone help explain which corners are best for round/angling. a side note: my port ends rather close to the side of my box, but its a port width away so no worries. i was wondering if i rounded the side corner its close to would it increase airflow/deebeez?

JWBryant Posted May 25, 2011 Report Share Posted May 25, 2011 The corners that he rounded were the "pressure points" of the box. This is where you put the pvc. Quote Basshead-in-Training Link to comment Share on other sites More sharing options...

C-Fizzy Posted May 27, 2011 Report Share Posted May 27, 2011 Honestly, unless you're gonna be looking for numbers, you won't be able to tell the difference. But definitely round the corner where your port is. Quote under construction I hate People with crappy primered cars rolling on hubcaps that are louder then me. u hate c-fizzy?

fecupe2001 Posted May 27, 2011 Report Share Posted May 27, 2011 Yeah, but having 45´s, adding resin, routing edges and all those things together would get you louder not only on the sensor, but to your ears also, no i didn´t explain it using a slot port since PVC is cheaper and easier to work with, i´m gonna try a few things with a slot port this weekend but 45´s should be almost the same since the box is sub side/port back like the other boxes, so pressure points are the same...

nickers Posted May 30, 2011 Author Report Share Posted May 30, 2011 Would it also be best to put a roundover in the port bend? Quote chevrolet all day er day. '81 camaro z28 performance '03 silverado ext cab show and go Link to comment Share on other sites More sharing options...
