If you've already bought our 1TD kit with the Standard crossover, you can still upgrade to the Superior crossover with this add on. The Superior crossover squeezes that last little bit of performance out of the Criton kit by upgrading all of the crossover parts from Dayton Audio to high end parts from Erse, Jantzen, and Mills.
The upgrade brings out a wider and deeper soundstage with better instrument separation. Vocals are presented in a more natural way with more focus and smoothness overall. Many customers comment on the upgrade removing grit or grain from the sound.
This upgrade kit includes all upgraded crossover components, new crossover boards, and zip ties.
