Traditional Stack (X1s, HD15s) New Midtops

Greetings all,

I'd be nowhere without all of the information provided on this forum, and I'm glad to have completed my first system build(although I've learned a lot along the way and would have done a few things differently in hindsight).  

The X1's are loaded with the Dayton Odeum 18n, and the HD15's are loaded with the Dayton PA380-8.  The Midtop is my strange physically time-aligned design(Qbert?) and features a PRV Audio 3-way crossover @750/5000hz, with: a horn loaded with the PRV Audio 12" 12W750A driver, a midrange phenolic horn loaded with a Selenium D250-X(-7db attenuation), and a PRV Audio TW700TI tweeter in a custom waveguide(-4db attenuation).  

It is powered by three Behringer Amps: an NX6000 for the subs(2*1600w rms@8ohms), an NX4-6000 for the kicks(4*440w rms@8ohms), and an NX3000 for Midtops(2*440w rms@8ohms).  I ordered an LMS over 5 months ago and won't receive it until July, but for now am using an analog 2-way crossover and the amp's 100hz hi/lo pass feature to run(in stereo) the X1's at 25-52hz, the HD15's at 52-100hz, and the Midtops at 100hz and above.  I imagine the ideal frequencies will be closer to 35-52hz, 52-130hz, and 130-20khz.  I'm very surprised with the efficiency, as it runs fine on one 20a circuit even at very loud volumes.
