I have an academic interest in the Palmer because, unusually, I wouldn't trust myself to build these speakers in a similar form myself—and if I did, they would probably be just as expensive, if not more so, without even factoring in the labor.
Normally, I select the appropriate drivers, calculate the enclosure, activate it with a Hypex plate amplifier, measure it with REW, and then tune it via Hypex DSP and PEQ.
I can't manage the die-cast enclosure, such a low cutoff frequency with this small enclosure and impulse compensation with two 8-inch woofers and a coaxial speaker on the front – difficult.
Besides, I've never worked with FIR filters before.
So yes, I'm interested, and I'm looking forward to my own listening experience.
