So, where did you find them for $1K a pair?
Everywhere I found they were $1350.
"The main issue is the lack of dispersion at only 90x90 degrees."
So what do you think a 1" dome tweeter is at 16Khz? (try about 60°) Properly designed horns beat cones and domes every time, especially when it comes to power response.
" Also, I don't believe it's anywhere near 98db efficient in real usage, more like 94/5db."
It's not 98dB, Klipsch adds 3dB~4dB for room gain, and then it's really 4Ω at midband where the most program material is, so it's really 91dB~92dB/W (referenced to its actual impedance, especially with a tube amp).
I really like the way the marketing department can get away with calling a horn that is round, with what appears to be straight sides, in the most important parts of its expansion, and then call it "Hybrid Cross-Section Tractrix Horn"
"Dual spun copper Cerametallic woofers"
GMAFB, they're color anodised aluminum.
"The compressed molded rubber construction adds high-frequency damping to reduce harshness and improve detail."
That should be better than the cheap plastic they currently use in most of their line (if they have done the compressed rubber correctly).
At HEIGHT: 43.06" (109.4 cm) WIDTH: 10.55" (26.8 cm) DEPTH: 18.32" (46.5 cm) that's about 3.5 cu ft internal, not allowing for the displacement of the horn, drivers, port, bracing, etc.
A 2 cu ft 2nd order sealed box with an F3 of 30hz can only be 0.18% efficient (84.55dB). A 2 cu ft 4th order vented box with an F3 of 30hz can only be 0.36% efficient (87.56dB). A 2 cu ft 6th order vented box with an F3 of 30hz can only be 0.90% efficient (91.54dB).
So the 32-25kHz +/- 3dB is clearly a lie (for the claimed efficiency and box size).
All this said and done, I'm sure it is a fine speaker, and it looks like it may be worth its $1350 a pair price.
