Very cool web site. Do your design best Martin Logan's in the end?
I have not heard the latest ML models, let alone in the same room. That said, and based on my recall of the older ML Summits, I would say that my speakers best the ML's older ML Summits in almost every respect: Imaging, blending between the woofers and stat panels, overall slam and treble response. But then, my speakers are less compromised in many respects, as no consideration was given to sales or profit.
I attribute better bass blending to the choice of a low-inductance woofer coupled to a lower Q transmission line. And flat panels give more focused imaging and greater slam than curved panels. Also, my panels use lighter 6-micron (vs 12-micron) diaphragms, which yeilds somewhat better treble response. Additionally, my speakers are bi-amped with active digital crossovers-- not cheap but superior to single-amped passive setups.
What I can't do and ML can is design passive crossovers that work well enough to allow building non-bi amp'd hybrid ESL's that sound good. It's horrendously difficult to build a balanced hybrid ESL with passive components. And this you must be able to do if you wish to build ESL's cheaply enough to sell at a profit.
