Surprisingly pitch accurate loudspeaker

Musician

Sibelius from Pearl acoustics. These are the most pitch accurate speakers I have heard in the last two years. An example of the fact that there are modern good products (in addition to Lejonklou, Linn, Naim, Rega etc.)

These Sibelius speakers have some disadvantages, they cannot play very loud and they must be set up correctly in the room (something that all good speakers are characterized by). A few centimeters misaligned and you lose a bit of the magic and the live feeling.
If you listen a lot to recordings with real acoustic instruments, you notice that the instrument characters come through very well, while the pitch of each instrument never becomes unclear.
I link to a test by Steve Huff, he gets it exactly right in his review:


And another reviewer:


” I have to declare a bias heavily against single (dynamic) driver speakers. They have never sounded good to me - boxed, open baffle, mounted in massive cabinets with intricate and extensive folded horns - they all have underwhelmed. Lacking in the frequency extremes (no real surprise there), but, more importantly, completely falling apart when the music gets complex.
But here's the first exception to that experience, the beautifully crafted solid oak Sibelius from Pearl Acoustics. They use a unique Mark Audio provided driver and cost around £5k. These are stunningly good. No, they don't go very deep, but they go deep for such a small driver and the go plenty high enough to feel like there's nothing significant missing from the experience. Musical, tuneful, dynamic, smooth and they don't fall apart when you throw something as complex as Malia & Boris Blank, despite the amount of bass the tracks contain. Excellent.”

Has anyone listened to these speakers and what did you think of the sound ?
 
I was curious about these but read several comments "not great for rock / metal". For that reason I'm oot. But for what they do specialise in they seem to get high praise.

Guess it would be nice to have multiple set-ups to swap speakers in and out according to music/mood. One day, maybe. For now, I need a jack of all trades.

I am very surprised that is the case considering that they're single-drivers... I even doubt it.
I've owned single-driver speakers in the past and would not touch the kind again with a barge pole.

I thought the same - until I heard this speaker.

Here is another review :
 
Yes, its all about the perceived sound articulation.

Which means nothing, really.

Pitch is frequency. Frequency accuracy can be measured and you just can't get frequency accurate from an un-EQ'ed single-drive.

Many microphones are not pitch-accurate either, and because most the recordings are not accurate you can't judge a speaker's pitch-accuracy through listening (even if your source and amplifier are very accurate).
 
If you want speakers with really good pitch just get a pair of refurbished Gale 401s.

Objectively they are not:

There are two types of speaker, those that produce music in your room in a way that that you enjoy without constantly analysing how it sounds and those that to some degree distract from what you are listening to. You can try to justify preferences with all sorts of narrative but assuming you give each auditioned pair the best chance of performing at their best position wise, it really is that simple.
 
The looks and price don't really match to be honest.
I do believe single driver units can perform rather well, within their limits.
There's a market for everything hifi.
Would love to hear them myself.

Pitch is frequency, but it's also timing. Any note from a musical instrument is a combination of multiple tones - the fundamental 'pitch' note, and harmonics generated by the instrument. If these harmonics become misaligned during the reproduction, the pitch, or the tone will sound 'off'. So a loudspeaker which lets all the harmonics arrive at the same time as they should, rather than delaying some relative to others, will sound more pitch-accurate. Single driver loudspeakers, with no crossover, should be inherently better at this than loudspeakers with crossover networks. Then it's a question of whether the drive unit itself can accurately reproduce enough of the note's envelope to remain convincing.
