Enough baby talk
Have not started voicing yet just making sure I have a flat response to start with, you can se even at a little above 90dB distortion is mostly below 0.5% and that is with a washing machine running 15' away.
So far it sounds quite good indeed
MF to HF passive crossover is extremely simple, just a cap and coil and crosses at 6-7k (I can't really exact number remember all have to look back to figure out what it was). It maintains a flat phase response through the MF/HF crossover.
At moderate listening levels (need to raise your voice to talk over it) the A500 I have powering it right now was just tickling the -30dB lights
