You have some nice gear. You mentioned a DBX223LX crossover-- I used one of those some years ago with my DIY hybrid ESLs and found it to be a very nice unit. I recently replaced the DBX223 with a DBX Venu 360, which is the most fantastic piece of equipment (other than my speakers) that I've ever owned (can tweak crossover points, EQ's, digital delays, and shape the sound any way I want, all in real time from my listening spot on the sofa using the Ipad control app). Big fan of DBX gear here.
Glad to welcome you to the CarverSite!
