BGGD_GMC Posted November 6, 2011 Author Report Posted November 6, 2011 Bend the port so its like an L on both sides? or only the L if i do subs on left and port on right? Quote
BGGD_GMC Posted November 6, 2011 Author Report Posted November 6, 2011 i know how to do the bottom box just the top box that gets me confused....any help? Quote
ryan916 Posted November 6, 2011 Report Posted November 6, 2011 (edited) Think of the top figure as two L's put together. Although that one is not drawn to scale the port exit width should be double the width of the entrance from each subs "chamber", if that makes sense. Edited November 6, 2011 by ryan916 Quote
