I’ve had several back loaded horns: CarderSound, Horning, Lamhorns, and Lowthers. Through trial and error, I’ve found they’re a much different animal than my front loaded horns, transmission lines, and conventional box loudspeakers. Like me, you may find a lot of what you thought you knew or how things look on paper quite different from how things work with these.
Although I’m not the biggest fan of the SET built around the bigger 211 and 845, they more than proved the best match with this type of loudspeaker, with the smaller SETs coming in next. The 211 and 845 simply put power into them in much better way, and came across as having much more seat of the pants power and better drive them than my push-pull tube, OTL, and solid state amplifiers
