Congrats, nice approach,.ie., LG clone powered LMS, w/eD cab. I've always considered these eD cabs, combined w/the LMS drivers a compelling recipe for world class bass, scale-able, add more to taste...
just add optimization.
I too considered eD making me some cabs a year or two ago. I went a different direction, however those cabs appear phenomenally heavy, and just bad-ass. So good lookin' out there. Interesting comments wrt
perceived output etc, relative to the Conquests. No question the Conquests would offer epik

output at tune and above. Clearly the attributes of the current rig are low distortion and sealed alignment extension, and if you're wanting more output, it's gotta be either bottom octave stuff, or resides higher up and it's rooted in some cancellation effect of some type. I don't know, just throwin' that out there.
I'm glad to read you're happy with the ambient noise off the amp in the manner in which you use it. I'm not much on lowering the cooling spec after the amp leaves the factory. I've always found work-arounds such as hush box type acoustic mini treatments around the offending area of question, etc. So that's cool that it's working out the way it is.
A few Q's; did you manually implement a LT correction? Ease of optimization and integration w/the mains? What wattage do the clones put out @ the impedance seen by the LMS drivers, can you bottom them config'd as is? Any room measurements you could share? Total weight? Have you measured any voltage or current readings while pushing the amp/drivers?
Sorry about all the questions, but I can really relate to the manner in which you approached this entire thing,...as I've coveted those very mains, I've considered this very route toward subs, etc.
Thanks and good luck
btw; I'm diggin' the line arrays

Very nice...but c'mon, how about a third one and an AT screen?
