There are two recent reviews of the LFT-8c that are quite good. Robert Greene's in this issue of TAS as hightlighted by the OP. The other is a thoughtful review by Jules Coleman for Enjoy the Music.com which appered March 2024.
Regarding placement, I follow the 40-60 rule for planar speakers. Placing the speakers at 40% the length of the room. My room is 30ft x 11.5 ft. I have the speakers 14ft from the front wall, 7 inch to side wall from edges. They fire straight down the line with no toe-in due to my placement method. This is an unusual way of placing speakers but the bass is very precise, soundstage usually beyond the edges of the speakers, and front-back layer / depth is very good.
One issue I have with all the reviews on the LFT-8c is a lack of discussion on the DSP feature of the 8c. I think this is one of the more 'controversial' aspect of the speaker. The new woofers are in dipole configuration ( 8" front firing and 6" backfiring out of phase ). And it is an active woofer unit employing a Dayton Audio 250W amp with DSP. All signals go through a A-D and D-A conversion in the woofer unit before it goes to the your amp which drives the tweeter and mid range panels. I love the sound of the speaker and the DSP implementation. But I say 'controversial' because some long time users of the ET speaker, some here on Audiogon, have express reservations. And I don't understand how a comparatively inexpensive speaker using an even more inexpensive active woofer unit with DSP can sound so good.
@nogaps I would be very interested to read your comments once the new woofers are installed.
