This upgrade addressed multiple problems with this model correcting the phase issue, driver break up problems, and amplitude variations. The entire crossover, binding posts, wiring, and the tweeters in this one are replaced. The new crossover uses much higher quality parts using all poly caps, a Sonicap for the tweeter circuit, all air core XQ inductors from US Coils, high quality resistors, all new high quality wiring, solder, and heat shrink. It even includes a sheet of No Rez to help damp out the cabinet wall resonances of those side panels. The cost of the upgrade kit is $525.
