Emerald Physics history and model progression

Does anyone know the history of Emerald Physics and differentiation of models? I find EP, CS and KCII series (there may be more). What's the difference? Which specific models are milestones? If I wanted to try the model that represents their best achievement, which would it be?
Have access to a library of miniDSP units (for active crossover, including DIRAC), 12-ch of quality amplification, and stereo pair of OB-subs - if that is necessary to get the most from them.
Intend to A-B compare and measure (in-room) them against LXmini.
Thanks for any info regarding this brand!

Good to know about wire can be upgraded.
So what I gather is the CS-series = Clayton Shaw
And EP and KC came later with Underwood. What does EP and KC stand for?

Guessing EP stands for Emerald Physics. No idea about KC

I had the original CS2 for a several years with the behringer upgraded by Cullen. Was a great speaker. The crossover died, Walter had bought Ep by then. He had me purchase the DSP 2.4 as a replacement and it was awful. Gave me a really good deal on a pair of 4,4's which he promised were far superior to the CS2's. Unfortunately those were awful too. So purchased a pair of Spatial M3's as Clayton had made the CS speakers. Definitely better than EP but still lacking in low end. Now own Pure Audio Project Trio 15's and these hit the spot for now.

@giggsy Which full-range driver do you have in the Trio, and why?

I have the horn driver. I auditioned the horn and the Voxativ AC 1.6.
The Voxativ was more forward but the soundstage was limited to the space between the speakers, The Horns throw a huge soundstage with nice separation. I replaced the "internal" wire with Cardas and upgraded the caps and resistors and now they make your hairs stand on the right recording.
