well i have been on a cab quest as of late,..(i got the chance to play through a marshall 8x10 cab,..and was blown away,...and i was curious as to why this cab sounded so awesome!,..was it the speakers?..or was it the cab design??)..and i have been doing alot of research on cab construction and how it effects your sound,...at first i was amazed at how little thought most cab designers put into there designs!!,..like zero thought!,..most just make the cab big enough to hold the speakers (i read an interview with jim marshall and those were his words!)...and then most others just copied the marshall cabs!!...bass cabs are probably the best thought out/designed,..heres some things to try if you have a "flubby" cab.
-buy some baltic birch,.(thou there is some debate on using softer/harder words for tunning your cab),..and make some dividers with holes in them..(check out the MILLS CABS, web site...it's what they do that no one else does,..and this is the only difference in there cabs than any other quality cab that i have seen so far anyways,..could this be there magic ingrediant?)...the mills cabs use this perferated divider down the center of the cabs dividing the left and right sides,..this does 2 major things,..makes the cab volume less and controls some off the sound comming off the back of the speakers,..(dont forget the back of the speakers moves just as much air as the front)....i have been thinking of making a "mills" type divider that not only goes vert. but also horiz. !!...
-use some of that bogner foam or whatever else ya wanna try thats easy/cheap easy to remove and line the entire inside of your cab!,..some sound engineers say that the only thing it does is reduce the size/volume of the inside of your cab..
-DISCLAIMER- i have been doing my cab research for about 2 weeks,...so i am lucky if i am in that "knows just enough to be dangerous" category,...
but i am making the "mills" divider as we speak!..i'm gonna do some experimentation,..and hopefully do some clips of the before and after,..
i know the MILLS cab dude pokes in here every now and then,..i would love to pick his brain,..since it seems that MILLS,DR Z, & GENZ are about the only guitar cab makers out there actually putting thought/design into there cabs.
