Starting a thread to chronicle the fun of going fully active with my front stage so I don't keep polluting other threads.
The L and R are the modified JBL 4722s, with have a 2452H-SL compression driver with Truextent Bex4008 diaphragm on the 2384 waveguide over a pair of 265H-2 woofers.
The center will be using a 2453H-SL on an STX825 waveguide with a small spacer over a single 2265G-1. Still waiting on JBL to ship the woofer :/ It seems these CDs like a 1/2in spacer, so will be making some for the L/R too since they use the same phase plug. This cleans up a drop out at 12khz. I'm using a 100uf cap for DC protection and a 3636 autoformer as a 12db pad.
So far I've build a trio of NC400 amps, each dual mono. These are silent when the input is shorted.
I started this project hoping to use some opendrc-an's, but their noise level is a bit higher than I'm comfortable with. Now I'm looking for a decent interface and going to try a PC based solution.
more updates to follow, but here's a pic for now.
