If we don’t have sufficient detail about how the recordings were made and corrected for bias, how are readers who weren’t involved in this experiment supposed to know whether the results are real or if they’re actually an artifact of a problematic experimental design?
I agree with the above, and most of what
@preload said.
Was there control for
Order Effect?
Was there control for
Carry-over Effect?
How recently had the participants heard
LIVE music of similar style?
Klipschorns of that vintage needed to be
SEALED into a corner with closed cell neoprene, or compressed pipe insulation or the Klipsch sealing kit. By the way, it is estimated that there was one appreciable change in the Klipschorn every 10 years, on average. The ones I know about are 1 in 1957, 2 in 1963, 1 in 1980, 1 in 1983, 1 in 1987, 3 in 2002, and 2 in 2020.
One of the few things Edgar Villcher and Paul Klipsch agreed about was that,
in many, if not most, rooms, if someone moved their head [or a mic] a few inches, the frequency response would change. In modern times, most people somehow combined the response from several mic positions
[tight around the head of a single listener -- the proverbial head clamp -- or with some kind of compromise(d) multiple mic positions spread around a wider group of listeners
]. The combining process ranged from an average to a "fuzzy logic" solution. Here is one of my Klipschorns (AK4), with Bass Tone Control at + 6 dB, and Audyssey Reference (causing a Harman-like downward tilt) in my 4,000 ++ cubic foot room, at 13 feet away, as "heard" by a calibrated mic in 8 positions, in a field about 3.5 "seats" wide on a couch, at ear height. The sweep starts at 43Hz, because
that is where the crossover to a subwoofer begins [actually 40Hz], and I wanted this to be
K-horn only.
In response to the person who said, "I thought people bought them for bass," while a little EQ is usually used, bass impact (Fanfare for the Common Man, The Great Gate of Kiev, the end of some Mahler or Beethoven symphonies)
without a subwoofer, will flap one's pants legs, and seem to move the couch, and bend my desk out of square.
FWIW, I have played in 5 orchestras, listened to many more, and, although I haven't heard the Revel, nothing I have heard has the
convincing brass, piano, woodwinds and percussion of the Klipschorn. Some others do strings better. I'm confident that, for a much higher price, there must be several others.
I am aware some are saying speaker distortion matters not, but here are some notes, FWIW:
