SpeedTriple44444 Posted August 30, 2010 Report Share Posted August 30, 2010 So, how does it sound?Interesting bracing. I usually do some 3/4 x 3" strips glued on end on the larger areas to break up resonant modes (unequal spacing). Quote Link to comment Share on other sites More sharing options...
rawlins87 Posted August 30, 2010 Author Report Share Posted August 30, 2010 Sound good, bracing works well for high spl applications with little to no turblence or standing waves.Once it got put in the truck the cabin rise of the truck is liking the 40-50hz frequencies very well. Anything under 40 is getting to much vehicle flex, this weekend im building a 2" extension to the port to lower the fb, and in doing this i hope to lower the overall sensitivity of the enclosure so that once cabin gain takes its toll it has a flatter response.
