it's a Faital Elliptical: https://www.parts-express.com/FaitalPRO-LTH142-60-x-50-Elliptical-Tractrix-Horn-1.4-4-B-294-1042?quantity=1

I sit 8‘ away from a 100“ screen and 3-way horns as my mains. It. Is. Immersive.

first place to start is with the washers between the mid horn and the driver, provided your LS have the K-400 and K55 combo. The washers get hard and create distortion. I'm not sure if I'm allowed to tell you where they have them in stock.

I multi-amp my three-way horns with 6 mono blocks. I balance the amps by measuring with a calibrated mic and REW, making adjustments to the DSP until they're set correctly.

That sort of thing is frowned upon here these days.

I'm using a pair of Glow Audio Amp Two that have been recapped with Mundorf M_Cap Evo Oils and Nichicon KZ Muse electrolytics and modded into bridged mono blocks, via XLR to balanced RCA interconnects. They're driving the mids, along with a quartet of Fosi Audio ZA3 with Burson V7 Vivid and Classic op amps, that are driving the bass and treble in a pair of 3-way horns.

Turnbull is an up and coming artist with a lot of buzz. This is affordable for what he does.

Oxalic acid can be used to remove stains, which is the active ingredient in the product you've linked. It's also the active ingredient in Bar Keeper's Friend, which is likely more affordable (not that the product in the link above is particularly expensive).

wait til you see what his kid did with them...🤣

They’re made with 4” Owens Corning 703 fiberglass board with an open back and covered in printed burlap. They work well from 3000 Hz to 55Hz

my room. listening area is small, but the room itself is moderate in size

I’ve only seen them with 1/4” and RCA connections. It may be possible that the 1/4” were balanced TRS, but I’m skeptical of that.

My setup, apart from the active crossover, is pretty simple. Sources, a Schiit Bifrost DAC for the digital ones, phono and preamp for analog, a Schiit Freya preamp, balanced output to the FIR DSP408; 4 class D mono blocks and an el84 valve amp to my horns. I use PEQ for crossover filters and to tame resonances for a frequency response that’s +/-3db from 23Hz to 20kHz, but other than that, I don’t use tone controls or dynamic range expanders. I’ve considered putting in a BBE sonic exciter into the chain, but I’m moving towards all balanced connections, I’d rather not introduce any additional noise and ultimately, I haven’t found the need for it.

I simply haven’t found the need to use it. I would likely be more inclined to replace the offending component than mask it with a noise gate.
