Quartz Restoration
« on: 20 Jan 2018, 03:17 am »

I am starting the restoration of a pair of ACI Quartz 3-way speakers and hope to perform a few upgrades while I do.  New wiring, new foam and new crossover components.   If anyone out there has information on the crossover, the manual or the kit instructions please let me know.

I've removed the deteriorated foam and the crossover.  Here's the schematic of the crossover (I'm not 100%  sure that it's the original design) and a copy of the page from the ACI catalog. The woofer is a Dynaudio 17W75, the midrange a D54af and the tweeter is a D28.
