Gotz1lung Posted May 27, 2009 Report Share Posted May 27, 2009 It depends on the bracing you currently have id say. Id does help with airflow alot tho. Think of a car exhaust, if its got smooth bends the air flows better than the crinkle bent crap from Midas, same inside your box, Squared edges hinder smooth flow. You could pick up a tenth or 2 id guess if your box flexs alot, if the box is flexing, the pressure inside isnt exiting as forcefully as it could.

HHR Ed Posted May 27, 2009 Report Share Posted May 27, 2009 How many of what size subs? The angles may hurt in some setups, or do nothing. What can help depending on your cone area is reducing box volume and shortening the port.

matt402 Posted May 27, 2009 Report Share Posted May 27, 2009 remember that 45s will take some airspace out the box, but will help the air flow. if u make the port shorter it will tune it higher. Quote Link to comment Share on other sites More sharing options...

HHR Ed Posted May 27, 2009 Report Share Posted May 27, 2009 I can let you in on a little secret of mine. Use clay, put it in the corners of the box building them out at a certain angle, add just a little at first, then test. Then add some more and test again, then add more and test again. and so on until you have good data to go on. Then change the angle and repeat. If something works, leave the clay in and fiberglass over it. If it hurts you, simply remove the clay.
