Radiant Acoustics Clarity 6.2 - Purifi based compact speaker

I completely missed the sarcasm! Haha

Nice setup, but I would sell everything and buy a pair of Genelec 8361, Neumann KH420, Dutch & Dutch 8c or something in that range, upgrade the room acoustics and use all the cash that is left for something else. Why such expensive gear that makes so little difference? Dac, streamer, amp, power conditioner?

I counted roughly 35k on equipment on speakers that cost 4k.

It´s actually almost funny to see all this expensive cabling (even on cable risers) handing over the signal to the cheapest black/red wire available inside this speaker.
I´m not saying it will affect the sound dramatically but makes you think about what we are doing here..

You dont understand, the height of the cable off the ground is directly proportional to the height of the soundstage

Don't you see the $2,000 Synergistic Research Black Box on the floor, that's all the "Acoustic treatment" you need, seriously google it. "Audio" snakeoil companies selling stuff to break the laws of physics once again.

What you are doing here is mostly spamming for the better here for days now.

Completely pointless spamming with no substance.

It seems some of us are carried away a little by their own enthusiasm and the marketing machine. Looks like 21mm mdf, cheap cabling, simple bracing, 1 sheet of Basotect (actually not an expensive material), edges inside nowhere rounded of, low end Bennic caps..
Again, the build is decent and adequate for the job but I´m missing the ´exquisite´ part here.

Making a speaker involves making compromises - no speaker is perfect or can do everything. That’s part of what makes building speakers so much fun!

Making the inside of the speakers look high end as well would have increased the cost a lot and no customers will ever see it, so what’s the point? We can see from our measurements that we have resonances and vibrations under control, so the cabinet does its job. The front baffle is 28 mm bonded with the 15 mm aluminum baffle. This sandwich-construction is what makes it work so well. The horizontal bracing coupled to the active woofers send vibrations to the side of the cabinet where they are not as troublesome. It’s simple but it works very well. No need to re-invent the wheel here.

We do use two pieces of Basotect, and yes, it is in fact many times more expensive that what is normally used in many other speakers. Because it works better.

I will not comment on speaker wiring and crossovers (again). I have also seen you comment on YouTube about the crossovers on these speakers. I welcome you still to actually listen to the speakers before you conclude they must be harsh sounding due to the Bennic components. If that truly was the case, don’t you think we would have chosen something else?

I'll check up with my marketing manager! We are trying stuff out to see what works...

Please share when you figure it out!

Please share when you figure it out!

Aha! I think you guys have a lot more experience in that! We are just starting out and throwing everything at the wall to see what sticks…

At least you have the HiFi klubben relation as well to help get sales. But it is interesting to see more companies exploring the direct-to-consumer route!

Thank you henz. Great post.

I understand and even it don´t translate to the measurements it´s still strange using such nice drivers while cheaping out on this stuff inside. For 50€/speaker more all this would be nicely covered.
I see people here using very expensive gear and cables to connect it to the most basic wire available.
No, I´m not a ´cable guy´ and you will reply that the wire inside has no influence on the sound because of the short run, but still..
I´m sure it would give a better feeling to many of us...it would be the finishing touch.

I much prefer no-BS audio over getting gut feelings covered.

50 Euro production cost multiples 3-10x in the final product. So that's actually a significant sum to sink into a crossover.

Thanks for this post,
I'm getting tired of hearing people blather on about a product that they haven't seen or heard in person. I'd like to take part in a comparison test where someone puts the Clarity 6.2 side by side with some product for the same money that is top to bottom "exquisite", has top-notch internal cabling, super stiff composite cabinet with superior bracing, Jantzen and Mundorf packed crossover etc.

I've had a lot of speakers in my listening room over the years and I can say that the Clarity 6.2s are beautifully made, the semi-matt wood veneer looks exclusive in person. The cabinet is very decently stiff and does not resonate when tapped and even with loud music. The front aluminum panel is machined and installed flawlessly. And most importantly: they sounds great! I don't know what more you could want for that money. (I am not saying that this is an untouchable product that cannot be criticized. There is always room for improvement. But the way the criticism is expressed speaks for itself.)

I don't know why people are still blabbing about it, it's not a big deal. They measure and sound great regardless.

Hi everyone
Erin was so kind as to help us investigate the distortion peaks on his measurements that has caused some debate.

It turns out it was a really practical issue; the aluminum backplate on Erin's early samples was slightly loose and rattled a bit as a consequence. I don't believe this should be an issue for any of the products sold as we have improved upon the mass production assembly quite a bit since.

Here's his description of the issue and his new measurements:

I figured it out! Turns out it was coming from the crossover. I let my test run 32x while I listened to the speaker up close. I noticed a resonance that I wasn't sure where it came from so I blocked the tweeter from playing using some cardboard and foam so I could focus on the panels. I then ran the sweeps again and I was able to isolate the sound as coming from the back of the speaker and when I pressed in on the crossover it stopped. So, I used my torx bit to check the tightness and noticed some bolts weren't as snug as they ought to be. I tightened each of the bolts (using the cross-tightening method), re-ran the sweeps and I couldn't hear the noise anymore. I removed the foam/cardboard from the tweeter and ran the test again and these are the results I obtained:

What do you think? A broad tip Solder iron at moderate heat, a bit of hand gymnastics and your 'non Purifi' woofer surrounds could look the same .

This is very nice to know, and excellent news.

Do you know if that also translates into the multitone distortion figures, which were good for a speaker its size but not excellent?
