I would like to recommend Audyn bypass caps as per image as a great en inexpensive way to improve the sound of your speakers
I recently redid a set of crossovers for a set of Jamo CBR1702 with some nice quality parts, the end result seemed a bit rolled off compared to the electrolytic caps. I have experienced this with some other speakers as well when chanig out the electrolytics with polycaps. But bypassing the tweeter polycaps brought all the crispness back that was missing.
Also had success in a Quad 44 Pre amp with the Audyn bypass caps
