Radiant Acoustics Clarity 6.2 - Purifi based compact speaker

I heard both the 6.2 and 4.2 at the HighEnd in Munich.

They both had plenty of base extension. I did not miss anything in that regard.
The presenter mentioned that the main difference of both is that you cannot turn the 4.2 as loud as the 6.2.

From my short time listening there I can definitely agree with that claim.
 
Both speakers have the same twitter.
Bigger model has a waveguide and these dispersion fins, which are not present on 4.2 as according Radiant acoustics there are not necessary(due to the size of the cabinet I understood).
I had the chance to listen both speakers during the Munich audio show and the amount of bass this new tiny model produces is mind-blowing.
 
About 12 years ago, I threw out my big speakers from the 90s (Infinity Reference 61 i) and switched to the KEF LS50. To keep things fun, I added a subwoofer (SVS SB12-NSD) to the minis. That was quite okay. A year ago, I replaced the KEF with the Opticons 2 MK 2 from Dali. Also very nice. Now it was time for something new and permanent. The money had to go :facepalm:

I've had the Radiant Acoustics Clarity 6.2 for exactly three weeks now.

Before buying, I visited a few hi-fi dealers in the area and listened to some compact speakers. These included the Dali Epicon 2, a couple of Monitor Audios, the Raidho X 1.6, and some B&Ws.

My reference or my “dream” is the Fink Team Kim (Karl-Heinz Fink has his company headquarters in Essen, Germany, just a few kilometers away from me). A fantastic speaker! Due to its size, the Kim is not actually a compact speaker, but despite its size and integrated stand, it would have fit well in our living room after disposing of some furniture. Even the WAF was in favor, but I decided against it in the end. More on that later.

Our living room is basically too small for speaker stands or large speakers. I didn't really feel like changing anything or losing much-needed storage space. Ideally, everything should stay as it is. The optimal place for speakers is on the lowboard, but here the speakers are relatively close to the wall (approx. 10 cm to 20 cm away). A bass reflex port at the rear could therefore cause problems. The height of the speakers should be a maximum of 40 cm, otherwise they would protrude into the TV.

Overall, the Radiant Acoustics played into my hands here. The conditions for good integration into the living room were met.

At the dealer's, I first listened to the Radiants with a Lyngdorf amplifier (TDAI-1120). Without a subwoofer, but at a volume that made the membranes move more than a thumb's width out of the enclosures ;-) It was impressive. The speakers remained relaxed throughout. There was no distortion or unpleasant booming.

A few days later, I took my power amplifier to the dealer and tested the Radiants with it. I have had an Apollon Purifi single-ended 1ET6525SA ST stereo amplifier since early 2025. Purifi comes from the same stable as Dali and the Radiants (Bruno Putzeys and Lars Risbo are partners of Peter Lyngdorf), so the amplifier should be a good fit. And it does :). When called upon, the Apollon delivers 425 watts at 4 ohms without any problems. That's enough even for power-hungry companions like the Radiants.

After three weeks at home, I can now give a good assessment. My setup: WIIM Pro Plus streamer, music comes mainly in high resolution from Tidal, preamplifier is the Singxer SA-1 V2, amplifier Apollon Purifi single-ended 1ET6525SA ST, subwoofer remains the SVS SB12-NSD for now (I set the crossover frequency to 60 Hz).

This is the end of my wish list. The sub brings more volume into the room, relieves the Radiants in the lowest range at the same time, and from 60 Hz they can then go full throttle. Everything just fits here. The kick bass in particular is brilliant. Even at low volumes, the speakers sound very good. The mids and highs are also perfect for me. The stage is quite wide and deep. There's nothing to complain about here. The AMT gives the Radiants an extra clarity that I haven't heard in other speakers in this price range. Audiophile is just a buzzword, but I do find the speakers exceptionally good. It's just fun to sit in front of them and listen to playlists. I think it's great that the manufacturer offers a 10-year warranty. Not many do that.

However, there are also some disadvantages:
  • The speakers do not distort at all. Zero. This tempts you to turn up the amplifier more and more. Depending on the style of music, this is not always well received by the neighbors. Nor by my wife ;).
  • The vertical alignment has to be right. The AMT should be at ear level or at least aligned with it. I achieved this by placing it on the lowboard at an angle using acoustic foam. It looks unprofessional, but it serves its purpose.
  • You need an amplifier that can deliver decent power. Fortunately, I have such a power amplifier.
  • Oh yes. I almost forgot: 50% customs duty for US buyers? :cool:

I think it looks very nice with these pads underneath!
 
@Kill Baulitz nice! You can also use IsoAcoustics stands like these below to increase height and hopefully the wife approves its visuals. Note that you can fine tune height in the front versus the back tubes so that it points to you.

Interesting that you don't toe in the speakers towards your listening position. Why did you chose this setup?

Do you use EQ to correct for front wall SBIR?
 
I went to HighEnd this year where according to the presenter Peter Lyngdorf did the setup for the Radiant. No toe in whatsoever.

Looking at the data provided by Erin I think this makes great sense:

Measurements for speaker Radiant Acoustics Clarity 6.2

www.spinorama.org www.spinorama.org


Erin also talks about this in his review video. According to him these are meant to be listened to 20⁰ degree of axis by the manufacturer and he found his sweet spot to be 15⁰

The speakers have probably not yet reached their final parking position. I have not yet found the best horizontal axis in terms of sound. It seems to me that a slight inward tilt is advantageous. The sound fan (“waveguide”) in front of the AMT ensures that the sweet spot is relatively wide. Perhaps it doesn't matter whether they are on-axis or slightly off-axis. I also don't care about the SBIR because the speakers are in a living room and not in a separate, anechoic HiFi-room with acoustic dampers on the walls and similar horrible things. They are simply positioned in the way that works best. I don't (yet) use a EQ or a PEQ.

There are more important things, such as the cold drink in front of me on the table :)

Thank you, this helps to better classify your subjective listening impression.
