john253a Posted June 17, 2012 Report Share Posted June 17, 2012 (edited) just trace the 6" aero port on some 1" mdf, cut it out get some sink foam from the hardware store,(use the 1/4 or 3/8x 1/8 stuff) place it on the mdf all the way around twice( so you you have 2 circles) screw it to the port with the original port screws Now you have 3 tune options of 2,3 or 4 ports open (33,40 & 46hz) Edited June 17, 2012 by john253a Quote Link to comment Share on other sites More sharing options...
