white4d96 Posted July 2, 2009 Report Posted July 2, 2009 I am redoing the front baffle on my enclosure for two Alpine S-10s. They are in separate chambers of about 1.3 cubes tuned to 34Hz. I am increasing the port diameter by an inch. However, this requires a longer port than my box. Could I just use a 90 degree bend inside the box to keep the port internal? Or should I just suck it up and run external ports? Too many projects, too little time...

bkolfo4 Posted July 2, 2009 Report Posted July 2, 2009 It is fine. You can get standard bends and long bends (larger bend radius) at lowes. Use the long bends if they will fit.

white4d96 Posted July 3, 2009 Author Report Posted July 3, 2009 Is there a different way to measure length of the 90 degree bend? I need 21 inches to get a 33Hz tune with my box Too many projects, too little time...
shainemcconnell Posted July 3, 2009 Report Posted July 3, 2009 if the the bend is pretty round ....so find the radius and calculated the circumference of the full circle and divide by 4 the length is the center of the port so take that into consideration also 2010 IDBL Rookie 1 North American Champion 2009 IDBL Rookie 1 Fl State Champion 2009 EBB Fly Weight 3rd Place Fl State Finals 2006 Silver Grand Prix GXP :Diablo Audio Hellfire 1000.1, JL Audio 300/4, One 13W7, ZR650, VR690, JL Cleansweep setup.
