Upscaled Modded 4520

Reality Sound wrote: A mate of mine here has some 1850's. I will borrow one from him to try it out in the cab. This is only a prototype for testing purposes. It will be altered for med/small/very small chamber size, also 4,5,&6 inch initial 'gap' opening (under rear baffle) and every combination of the two variables.

any testing?

Been mad busy with Xmas parties, now getting ready for New Years gig, then Vegas for CES, hopefully after that- (Mid January) Will post when I get to it for sure.

i think this is 4530 variant. i have a pair 4520. they were fiberglassed when i bought them.2x15 each. nut busttin heavy. i ran them with evx 150's over a narrow bandwith in a 6 way(5 active) permanent non mobile array between subs and midbass. made concrete vibrate under foot. thanks to the music and 30 cal target shooting my neighbors hated me! it fun to be a hillbilly.
