If that were true, we wouldnt need blind tests

Radiant Acoustics Clarity 6.2 - Purifi based compact speaker
- Thread starter Tassin
- Start date
I was referring to the raw cost price of most budget/entry level speakers compared to the cost price of our crossover, not the retail price.
Anyway, it was perhaps a stupid comment. What I wanted to say was: I think it’s a good crossover

I would describe the sound as neutral, balanced, open. Because of the clean undistorted sound, I guess there would be little listening fatigue.
At the Dutch Audio Event I was baffled by the number of rooms and speakers that sounded colored, colored in the sense of tonality, a far from flat frequency response or dominated by resonances. Maybe some songs excel on that speaker, but I think this is an absolute design flaw.
Many fancy looking expensive speakers (and amps, cables, etc.) were considered a no go by me in a matter of a minute if they don't get this right.
More noticeable when you own speakers are so un-coloured.

I can’t think of any others off the top of my head, in time Ascilab will offer the Purify tweeter with their own design of waveguide which I believe will be unique.

I'm curious as to what Ascilab will do. They seem to like narrow but constant directivity for their tweeters. This is what they did for their SB Acoustics tweeter, it's a straight line at plus minus 50 degrees from almost 1 kHz to 20 kHz. I've seen that tweeter in a much wider radiation pattern. It is imho a fairly unique choice for a speaker that is destined to be used in a living space.
This is seemingly contrary to what Purifi is building their tweeter for, with a waveguide that is going to reach allow plus minus 70 degrees up to 20 kHz. But perhaps the tweeter itself (minus the waveguide) has qualities that makes Ascilab want to use it.
It is a large contrast with Philharmonic Audio's approach, he seems to prefer a wide radiation pattern for his tweeters, so he uses very shallow or no waveguide on this designs. But since Purifi is coming with a wide constant directivity waveguide for their woofer, he might use it.
Ascilab is also crossing over much lower in the A6B (1kHz) and it seems the deep waveguide (perhaps crossing into horn territory) helps with sensitivity.
Maybe narrower dispersion up very high is a consequence of the depth.
So classy. Those stands are amazing.
Indeed, this is a consequence of the depth of the waveguide. And I know that boosting the output of the tweeter in the 1-2 kHz was probably a concern for Ascilab.Ascilab is also crossing over much lower in the A6B (1kHz) and it seems the deep waveguide (perhaps crossing into horn territory) helps with sensitivity.
Maybe narrower dispersion up very high is a consequence of the depth.
But there were other choices, maybe another tweeter with more excursion in the 1 kHz region that doesn't need as deep a waveguide to have enough outpu on axis. Or they could have crossed a little higher and trade some vertical directivity for more horizontal directivity.
There were other engineering choice that would have made sense. But they preferred the one with narrow constant directivity over the other ones.

Just purchased Clarity 6.2!
Now for the worst part: the waiting (dispatch sometime next week I was told).
I will definitely post my first impressions here as soon as the shipment arrives and I will try them on my setup (see signature and photo). Will test on existing setup as on the photo (Moon 600i amp) as well as using another integrated amp, Gato Audio DIA 400S. Gato has 800W into 4Ohm (Moon amp has 250W). I'll see which amplifier will match better with Clarity 6.2.
Stay tuned!

Though it’s not our thread, I saw it while searching a keyword AsciLab.
For tweeter and waveguide: Less excursion is better for tweeter. As you said thanks to our deep waveguide, our tweeter doesn’t move a lot even with quite low COP. When it drives with max power handling, 100W for tweeter (250W / 4ohm from amp output) it only moves about 0.24mm. And the tweeter we using has 0.6mm Xmax (97% Bl range). It is 105dB SPL at 1M. I believe most of woofers will run out first than the tweeter considering typical music curve, (bass level much higher)
And for waveguide and directivity, smaller waveguide or oval type waveguide also can match horizontal directivity with woofer cause of beaming frequency of woofer. (For now, If we cross higher, the horizontal directivity will be more narrow at some range)
But it can’t make vertical response smooth as we made. Smaller or oval type waveguide occur less constant directivity around vertical response, typically being widen right before COP.
Last, our top frequency dispersion is wider than general. You can easily find some examples having 10dB DI above 10kHz. Ours have 8~9dB above 10kHz. Even only 1dB is a big difference as DI.
The tweeter itself has narrow dispersion due to its dome geometry, but our waveguide/phase plug design could make the dispersion wider.

Yes, I think this is in line with my opinion. A lot of other manufacturers prefer having wider horizontal dispersion, even if it means vertical dispersion is narrower. You prefer better vertical dispersion even if horizontal dispersion is narrower.
This is not a judgment, I am truly curious as to what people will hear.

Thanks for having detail interest about our speakers.
Our first three models are so-called zero point for us. Narrow or wide dispersion can be chosen by personal preference of a listener, but as constant as possible is our design philosophy. Wider dispersion like +/- 60-70 deg also exists our road map though it isn’t near future yet.

I believe that date is for regular commercial availability. The prototypes should ship much sooner. I hope.
Is it a two way?

What I have in mind is a sealed 2-way with a displacement of .7 - 1.0 cubic feet, which would give HT folks greater flexibility in vertical placement. But all this will depend on how low the tweeter can go.
I see, this is not what I'm looking for, but I do think there's a market for it.

I was on vacation in Norway at the end of August and saw a HiFi Klubben shop and decided I needed to visit. There was a pair on display when they may have been "pre-release" and I demanded a demo! It was good fun to talk with the friendly sales rep. He said it was very strange that he didn't have to explain Purifi drivers to me!
I tried some metal as my stress test (youtube: Between the Buried and Me - Extremophile Elite) and they played really cleanly but really missed the deep bass foundation to play loudly and left me feeling a little let down. The rep suggested we switch genres and put on a London Grammar track (youtube: "Hey Now") which sounded incredible. The soundstage was super wide, the bass had real heft and body and wasn't bright or sharp in the treble.
After reflecting on it, I think both are great example of the speakers performing really well. Listening to the same two tracks at home on a 2.1 system, the metal track has a TON of bass the speakers didn't try to play. What was left was very clean, but that genre just needed subwoofers to reproduce its bass convincingly. The London Grammar track sounded awesome at home too, but had another register of bass that I hadn't heard. Since that track had content spread more evenly from sub-bass through mid-bass, I had a better subjective experience with the speakers. They handled what was in their range with tons of authority and dropped quickly to avoid distortion from what they won't play.
I commend the team for making an extremely pleasant speaker. Nice job, @henz !
That must be real painful.
My experience was just a little different. I called the nearest HiFi Klubben 2+ weeks ago and asked for a demo. According to their website they had a demo pair available (with sales good arriving at the end of the week), so I went there the very same day.
The speakers were connected to a Lyngdorf TDAI-3400 with a proper RoomPerfect calibration (thumbs up for Lukas, the salesman). But the space they were set up in was open and really huge. Guess what? No problem at all. The combo easily filled the room with fabulous sound. It took me less than an hour to know that I want a pair. My TDAI-1120 is certainly quite a bit less powerful than its bigger brother, but I have a pair of Lyngdorf BW-2 subs to offload (and extend) the bass.
Then Lukas, the salesman, made a huge mistake. He told me that - despite of what the website said - he had another pair available, in white.
Immediately, I forced him to hand that pair over to me by throwing my money at him.
He mentioned that this was probably the first pair to be sold in Germany through HiFi Klubben, but I could hardly listen to what he said. Truth to be told, I haven't connected my subs yet. No, I don't think they won't benefit from doing so (with proper high pass filtering, of course). But for the kind of music I listen to the most these speakers are immensely enjoyable the way they are.Now all that's missing is the speaker stands becoming available ...
