New Kuoro Speaker

Hi

The Ukkonen still goes deeper. Similar power handling.

The Kuoro is still under development. We are talking with Purifi about waveguide optimisation.

I would caution everyone from drawing any conclusions about sound quality from recordings made in this way.

They are simply nothing like the real sound. Microphones do not "hear" in the same way as two ears and a brain. The mics pick up all the room reflections and sound whereas your brain will filter much of this. This is especially the case with omni microphones as appear to have been used here.

Ever experienced the cocktail party effect? Its a really noisy room, music and conversations, yet you can focus on one person's voice and hear what they are saying. If you tried this with a microphone you would really struggle to hear the conversation.

Hence these recordings sound terrible. Yes the speaker names are mixed up.

Hi Alan,

What about the new baby Kuoro? 🤪

Any chance of lending this speaker to Erin for review after the show maybe?

That one will stay in the UK, but another pair will be built when I return. So it will almost certainly end up at Erin's in a few months.

When is the release date? I believe you said they are ready to order on Facebook?

Will the Ukkonen be upgraded to the Purifi tweeter? Its directivity is awesome.

Possibly, however it will probably require a larger waveguide to match the directivity and lower crossover point of the larger woofer. In discussions with Purifi.

I would add that whilst it seems like an obvious thing to do to fit the new tweeter to the Sointuva and Ukkonen, customers really do love their current sound. It is a convincing argument to say "if it ain't broke, don't fix it".

@Alan March Congrats on the Kuoro release, the Sointuva & Ukkonen were looking kinda lonely there for a while ;), I just thought to mention that under the "News" thread there is a duplicate post of the Kuoro speaker release announcement, also the Kuoro product page mentions under the Cabinet section "The Sointuva is custom manufactured to order so the cabinets can be finished to your exact specification." it should be corrected to Kuoro. I don't know how I missed it but it mentions Sointuva right above the price as well as it being a "stand mount" speaker, a couple of Sointuva leftovers. 😉

@Alan March Have you compared the two speakers? If so, what do you observe in the bass/midrange/treble regions of the spectrum with music? I realize movies may prefer the Ukkonen for its lower bass extension.

BTW, the Kuro lists for US$6,590 ... just round it up to US$6,600 to cure my obsession with seeing clean whole numbers:giggle:!

@Alan March, I've seen over the years that having an even horizontal dispersion is one of the critical sound parameters in a loudspeaker, which makes sense in that many listen to speakers while seated. And that having wide vertical dispersion is not ideal, due to deleterious effects from floor or ceiling bounce. IMHO, this is much ado about nothing. Most floors are carpeted, so they absorb a great deal of sound. For those with wooden floors, which are reflective, placing a rug at the first reflection point normally resolves concerns.

Ceilings absorb sound, too, and the fear/concern is that the reflected ceiling sound would interfere with the main sound, which is overblown. I've seen many setups where sound reflectors are placed in the ceiling and rear of the home theatre for a more immersive sound experience.

Many of us like to listen to speakers while standing up. But I've found in my own speakers and others at demos, the image dramatically collapses when you stand up, due to the speaker's limited vertical dispersion characteristics.

Does the image collapse in your speakers when moving from the seated to the standing position?

The vertical dispersion of our speakers is very good, if not identical to the horizontal due tovthe physical driver didplacement. The soundstage does not collapse in a higher listening position. You will find more of a problem with ribbon/amt tweeters in this respect. You can always tilt the speakers back if needed.

I don't think that there is much convincing evidence that ceilings and floors present a massive problem per se. We are very used to listening in rooms. A floor, for example, is present in any listening environment.

However, any room with inadequate diffusion and absorption is going to be problematic. Reverberation time can become too high leadingvto a "confused" fatuiging sound and the in room response may be skewed and suffer excessive brightness.

Floors, as you mention are easy to deal with via rugs or carpet, however ceilings are usually neglected. In my experience putting diffusers on the ceiling definitely helps to improve soundstage and envelopment, plus will also help to reduce RT.

Great range of speakers now. Félicitations Alan…
For the tests…

ice ice baby vanilla ice rerecorded. Nice bass.
Huge on Ukkonen. 🙏🏻 Atmos also.
