IH8PunkRok Posted November 22, 2011 Report Share Posted November 22, 2011 yes. they take up a small amount of volume and thusly make your tuning higher Quote -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build Link to comment Share on other sites More sharing options...
BFF Larry Posted November 22, 2011 Report Share Posted November 22, 2011 does bracing inside the box with dowels and putting a 45 degree corner in you port affect the tuning of the box? dowels do, but barely noticeable. 45 at the port wall does affect tuning.

These are things you would have to test. my port is 3.5" wide. and from the corner of the L to the corner of the box its 5". but with a 1"x1" 45 degree angle it makes it 4.25". will it affect it alot? its just a small corner Ideally you would want to keep the port 3.5", even at the bend. Just cut a longer 45. Edited November 22, 2011 by OrionStang Quote SMD Super Seller My Feedback Thread Link to comment Share on other sites More sharing options...
13mwolson Posted November 23, 2011 Author Report Share Posted November 23, 2011 Ohh I get it so keep It 3.5" even in the long part of the port corner Quote Link to comment Share on other sites More sharing options...

Torres Posted November 23, 2011 Report Share Posted November 23, 2011 does bracing inside the box with dowels and putting a 45 degree corner in you port affect the tuning of the box? 45 at the port wall does affect tuning. how so? port displacement is already taken out of the gross volume of the box, so adding a 45 in the port does not remove anything extra from the gross volume.
