Worst measuring loudspeaker?

BMR modal driver is superb in this respect.
They also beam significantly in the last octave and suffer like all small full range drivers from high multitone and doppler distortion, that's why in good designs from companies like Philharmonic and Nubert they are still just used as mid drivers.
 
Hardly the worst, but £6k for a two way ( standard colours £500 more for special) and stands at £1800!

20kHz is just a distant memory….

My impression of the Klipschorn's sound is that the midrange has a shouty quality, and bass is thin and punchy, likely not going much below 50Hz. It's not my preferred sound.
 
Well they're certainly not a fan of bass, anyway.
Depends on the room. Mine's pretty helpful: around 18dB of boost at 40Hz. Without EQ, it makes small speakers sound big, and big speakers sound ugly.

It looks to me like they've designed with a "helpful" room in mind.

+18dB at 40hz probably comes along with a similar notch at another nearby frequency though... room gain is definitely a thing but this speaker has F6 at 100hz or so... you can get bluetooth speakers the size of soda cans that compete with that.
 
Looking at the bottom end makes me think someone is a linn Kan fan.
The classic early to mid 80s Kan had the response rise from 80 - 1kHz by 10dB or more in a straight line (worse as the 80s went on and KEF altered the B110 driver), then a death dive in the lower kHz region to a tweeter recovery set to roughly the 500Hz level. If used with anything other than a period vinyl player and preferably a Linn LP12, a truly ghastly sound... (see the HiFi Choice scans on worldradiohistory as evidence...).
 
I'm pretty fortunate: no big notches, apart from ceiling bounce. Easily fixed by converting the speakers to 2.5-way with another woofer near the floor.


FWIW, that response curve suggests to me that the speaker will have some output/power-handling at 40Hz, while small bluetooth speakers have zero. The -6dB point isn't the only factor that should be considered.

Wilson tunetot?
I don't understand why some don't post them directly which is also good practice when taking images from other websites.

So a plus 4db at 20khz, is that all?
Well said, the loudspeaker (like most Vivid Audio ones, see also Stereophile reviews with directivity measurements) measures fine - just not cheap - so I don't agree it deserves to be posted in this thread.

Well, unless you are blessed with fabulous even room gain like yours, I think F6 is typically more relevant than F20. ;)

I mentioned earlier in the thread talk with my reviewer friend who had the larger Borresen X6 speakers in his place to review - the next size up from the X3 Erin reviewed.

While he was reviewing them he described them to me just as he does in his review:
Large and deep sound staging, precise imaging, highs refined enough to be enjoyable, really punchy bass that he was having fun with. But in listening he found a hole in the midrange, just as Erin did.
He ended up seeing this in some quick measurements. Though ultimately he really enjoyed the speaker.

FWIW, snippets from that Boressen X6 review. You can see from the in room measurements they feature the same type of mid range dip as X3s did:

————————

Still running records, I cued up Vladimir Ashkenazy’s 1973 recording of Franz Schubert’s Piano Sonata in G, D.894 (London CS 6820). Here, I began to scratch my head a bit. After listening to a full side of the massive, planet-smashing power of this monstrous music, I began to feel like something was missing. I’m used to this album making my listening room feel like a tomb that’s a hundred feet underground. It’s ponderous music, relying more on the left hand than the right, and it relies on the power of the entire piano, of the instrument as a unified device, to make its point.

The X6s recessed the piano in space, moving it backward into the soundstage, which isn’t necessarily a bad thing, but they also removed much of the power of the actual instrument, making it sound thin and small. I listened to this LP a couple of times, while moving the X6s around in an attempt to reinforce the lower mids a touch. Spreading the speakers out wider and toeing them in so that they pointed at my ears improved things a little.

With the additional width and the toe-in, the soundstage increased in size and scale, which was a very good thing—more about that later. The lower-midrange dip was reduced in intensity, but still there. After I’d satisfied myself that I had the X6s positioned properly, I decided to run the X6s through the Anthem Room Correction process that’s built into my Anthem MRX 300 home-theater receiver. Now mind you this—I only use the MRX 300 for watching movies. I run the front L/R preamplifier outputs into my Hegel P3A preamp, with the MRX 300 powering the center and two surround speakers. I run ARC on any speaker that’s going to hang around in my room for any length of time, mostly to balance the volume levels between the main left and right and the other three speakers. I’m far, far from critical regarding home-theater sound quality. So long as it’s in the ballpark, I’m happy.

I’ll repeat in clearer terms—I did not use the ARC-modified signal to drive the X6s for this review. ARC provides me with a generalized, not-too-detailed view of what’s going on in my room—one that’s reasonably consistent from speaker to speaker. Looking at the room curve, I noted a fairly wide trough, centered at roughly 200Hz, that maxed out at nearly 10dB. This, it seemed, was where the power of the piano was hiding.

Børresen
The red trace is the measured response

Once I’d accounted for this trait, I continued listening without much concern, as there was so much to like about these speakers.

…..

There was much to like here with the Børresen X6. The bass was excellent, and up top, the X6’s highs were smooth and unfatiguing. The Børresens threw an image in my room that was delightful in its solidity.

I wasn’t that bothered by the X6’s lower-midrange dip. I’m quite adept at listening around deviations such as this. I did, however, find myself gravitating somewhat toward music that didn’t rely on this power region. I’d be remiss if I did not mention that several people who listened to the X6s in my room were put off by this frequency aberration.


———————————

I know that people here eschew such reviews and just want to be shown comprehensive measurements.

From my own perspective, I would see enough information in that review to let me know I would not be seeking out these loudspeakers for myself.
