Here is a photo of my main rack, left main and center channel. The rack is the 3 PS-200, 3 Urei 539's EQ's for front channels an M552 and 553 and Behringer 8024 for RTA. Speakers are Le-14 subs E-145's, 2123 and 2416's with 2344 horns Crossover points are 50Hz 300Hz and 1.5K. Center channel is an Urei 811C clone, rears are L20T's. This has been stable for over a year and a half now. Took a while to get to that driver set but I like it as is so I think I am sticking. I want to build more efficient rears, have the drivers 2118's/2404's just need to get off my butt.
