@mijostyn, yup, I know the Sanders is "a real ESL" (what's an "unreal" ESL? ;-), that’s why I above referred to it as "the Sanders ESL". Both the Sanders and the Eminent Technology LFT-8 are hybrids, with a dynamic woofer.
The ET employs an 8" bass driver with 1st-order high- and low-pass filters centered at 180Hz. It’s dual magnetic-planar midrange drivers operate from 180Hz all the way up to 10kHz (with no x/o in that range!), where another 1st-order filter passes off to a ribbon tweeter. 5’ tall, a foot wide and deep, $2499/pr.
