I have added the Klipsch R-41M to the Loudspeaker Explorer where it can be compared directly with other speakers.
Nope.You do your listening before measuring, for the obvious reason, right?
That's the preferred of course. However, it would be nice to see if the mods do anything in the improvement dept at all..Or maybe just buy a better speaker to begin with instead of wasting time modifying a mediocre set of drivers?
I'd posted this comparison in another thread. Not trying to get into a measurement drama, just showing for reference on the consistency of these bumps. Same patterns as the Klipsch.
That would be ideal. Assuming though that Amir is doing it while the measurements are being crunched, that’s not much worse.You do your listening before measuring, for the obvious reason, right?
I'm watching these reviews closely...waiting for the speaker equivalent of a Geshelli amp to appear.
Agreed. The same pattern can be found on other speakers too:

The wiggles are around 3 dB in amplitude so not negligible. They're high-Q though so they're probably not that audible but still, it would be nice to understand what's causing them. At first glance it looks like comb filtering.
I trust more in the preference rating than any subjective review so i try to ignore the listening test but if it should have any credibility at all this is very important. Everyone is subject to expectation bias, no amount of training or technical knowledge will cure that.You do your listening before measuring, for the obvious reason, right?
Nope.
The woofer output doesn't arrive before tweeter in a conventional design like this. Even if you have drivers physically aligned, the crossover will delay the woofer response.Let's assume that the measurement was taken above the optimal axis. In that case, the tweeter would be relatively closer to the mic than the woofer (than it should be), and you would expect to see the woofer's step delayed in relation to the tweeter's.
But what you see is that the tweeter's step is actually delayed in relation to the woofer's. That means that the tweeter is further away than it should be. To get closer to the tweeter (or to be precise, further away from the woofer), you need to move the mic up, not down.
For reference, this is what an ideal step response would look like for a speaker like this (2nd order XO @2kHz, BR box tuned to 80-ish Hz):

As you can see, the tweeter is supposed to "hand over" to the woofer (to borrow JA's terminology).
But in this speaker's case, the woofer's output is already arriving at the mic before the tweeter's begins to. The tweeter is around 0.2ms "late" on this measurement axis:

The Klipschs I have heard were unbearable to me. Shouty/shrilly!Someone mentioned in another thread that we should define the 'desired sound curve' by the FRs of the most popular speakers, figuring that sales would show what people most want. I couldn't help thinking that if you went for 'most popular' you'd end up with a Klipsch HTIAB, with these really bright horns.
I see 1db variations that seems consistent between the measurements in that graph. Am i reading it wrong?Agreed. The same pattern can be found on other speakers too:

You are wrong and Amazon.com customers are right, they are magnificent American loudspeakers
“The people who incorrectly think everyone's taste in speakers is different can perhaps explain why some people may want every note around 1 kHz in their music to be exaggerated.”
Just curious if of the listening tests done to derive the Harman curve you rate the speakers against, did all of the participants pick the Harman curve exactly or was it an average?
An average would suggest some preferred more energy at 1khz than others.
And just to clarify, the “correct” thinking is that everyone’s taste in speakers is the same?
