Today I received an email from Harry Yeung (September Newsletter)
The Audio First Designs Cadentia 3 is becoming more and more concrete!
This is the information I want to share:
Complete speaker from January / February 2026 on.
Building Kits from November 2025 on.
Also some new measurements (which are kind of between beautiful and sensational!)
and a picture.

Anyone who has the choice between an AsciLab A6B PR, an AsciLab C6C, and the Audio First Design Cadentia 3 is truly not to be envied.
To choose is to be spoiled for choice

To my dear subscribers,

I hope you are all doing well and had a wonderful summer!

Sorry for being rather quiet since my newsletter in May… The past few months have been particularly busy as I’ve been working hard to push progress on the new product development.

In this letter, I’d like to share a few updates with you—news about the new product as well as some other interesting projects I’ve worked on recently. It’s going to be a bit of a long read, so thank you for your patience.

1. About Cadentia 3

In my previous newsletter, I mentioned the new Cadentia series, and I know many of you have been anticipating it. Erin even told me a few months ago that some people were already asking when he was going to review the new 3-way… Slow down, boys!

Doing what is normally handled by a whole team of engineers and designers on my own has been a hell of a job—but I finally finished developing the 3-way standmount model last month! The official model name is Cadentia 3.

I’ve placed orders for all the parts, and production is now in full swing. I’ll also be launching a matching speaker stand, since the required stand height (~40 cm) is probably lower than what most people already have at home.

I’ve attached a preliminary production information sheet PDF to this email, which is slightly more updated than the one I sent in May.

The kit version will launch in mid-October, with pre-orders opening then at an early bird price of £2,480 (UK VAT included). Shipping will begin in late October / early November. The baffle will be matt black, like the Fidelia. A perfect winter project!

The finished version will also open for pre-order in mid-October, with an early bird price of £4,780 (VAT included). Estimated shipping is late January 2026.

I’m only making 25 pairs of cabinets in the first batch, with oak veneer and a matt black baffle—my preferred combination.

Other veneer options (Walnut and Rosewood) will follow later, depending on demand. Each unit will be assembled and undergo measurement QC here in Cambridge before shipping. Due to my limited capacity, production numbers will remain quite modest in the first year.

The matching stand (flat-packed) will launch alongside the kit version at £349 (VAT included). The package will include adjustable “flat” feet in addition to standard spikes—ideal for wood flooring and especially useful when moving the speakers around for fine-tuning.


2. Retailers, demos and launch event in Hong Kong

Since finished loudspeakers will become an important part of my business going forward—and given their price range—I believe it’s important to work with retailers and offer demos so customers can experience them before buying.

This will complement my direct sales model (which seems to be the norm nowadays). A few dealers have already reached out, and I’ve visited some with the Cadentia 3 prototype, receiving excellent feedback. Here’s what’s planned so far:

  • A demo of the Cadentia 3 will be available at Purité Audio in London and Lean Business in Ipswich once I prepare some samples.

  • I’m also working with a dealer in Hong Kong to arrange a Cadentia 3 demo/launch event in December this year.
3. Isola, the vibration decoupler product

Some of you may have noticed a product called Isola on my website, but never heard more about it.

It began as an isolation product I developed a year ago for Fidelia customers in Hong Kong, who had no choice but to place their speakers on their TV consoles (which resonated too much).

They worked very well, but hand-making them was too exhausting, so I stopped after the first batch. I’ve now resolved the production challenges and am preparing to launch them officially soon. More details will be available next month.


4. Blog section has been added to the website

This year, I started sharing more about my work and projects online. Some of you may have read them on the ASR forum. To make them easier to find, I’ve added a blog section to the Audio First Designs website. Here’s what I’ve posted so far:

Now I’m mostly waiting for the Cadentia 3 materials to arrive. After finishing up some consultancy work and Fidelia orders, I’m planning to take a week-long holiday in Italy at the beginning of October.

I’m really looking forward to hiking in the Dolomites with friends and relaxing in the countryside.

Thank you for reading, and I wish you a lovely day!
Best regards,

Harry Yeung | Founder

Harry bought a pre production pair here and they were stunning.
I have ordered a pair,

FR measurement is perfect, as well as THD. Great work!
FR -- both on-axis and PIR -- is excellent. Same can be said for ERDI and SPDI, thanks to the excellent waveguide. Vertical is pretty forgiving as well, in light of the form factor.

In terms of distortion, THD is alright (a little worse than the modern breed of 6.5" Purifi + 2x PR builds like my Sointuva AWG), but what's really impressive is the Cadentia 3's multi-tone distortion.

According to Harry this image was taking under similar test conditions as Erin's measurements -- and they simply blow my Sointuva out of the water in MD at 96 dB. Can't wait to build my set.

Reading up on this design and it's quite impressive. I'm not a huge fan of the front baffle an waveguide look but that's necessary for the performance. Excellent engineering.

If he ends up switching the woofer for the textreme unit waiting for v2 may be smart considering how fast these will go out of stock.
 
Those look amazing- I am in the market for kits and would grab these immediately if they were floorstanders with active bass or even had a bass module/stand available like some of Troels’ designs. I would throw a deposit down today for a kit in walnut veneer…

Is a semi-active 4 way tower version coming or are there plans for bass modules that double as stands? Highly interested and motivated!

I suppose you could always stick them on top of DOS subs of your choice to accomplish this... since the Cadentias' F6 is like 40hz you only really need the bottom octave.

It's a bit superficial but I agree. I was a big fan of fidelias elegantly curved baffle so I was hoping for a similar look for the follow-up, but you can't argue with performance like that.
 
It’s always interesting to hear others views on looks. I happen to really like the looks of the baffle on this one. I had the cabinets all built up and I’m just about to veneer mine this weekend.

I love how big the cabs are! One of the reasons I never went in for the Fidelias is I don’t like the look of small speakers. They need to be big!
 
Just finished building mine up… Took me a while as I wanted to veneer them. This took me the longest time as I’d never done it before and chose to work with raw veneer, which is a bit more difficult to work with over paper veneer (apparently).

All in all, the build was pretty easy if you have basic woodworking skills. Maybe you don’t even need the skills, but I would recommend doing another build before this one… A cheaper one!

My only negative so far is the black baffle marks SUPER easily, so go careful there.

Harry‘s instructions were great. Very easy to follow.

I haven’t listened to them yet as I’m waiting for my stands to be fabricated. Should have them early next week.

Looking forward to firing them up!

Wow those look stunning. Can you recommend any resources you used for doing the veneers?

I spent a lot of time watching videos on YouTube, reading through forums, etc. Ultimately I decided on doing a cold press type veneering. If I had a paper backed veneer, I would have gone for the 'iron on' method.

I used a raw veneer that is definitely more difficult to work with. It's more brittle and you need to be delicate with it, but is not too bad for a design like this, as all the panels are flat and no edge banding is required (apart from the rear, if you want to keep the back panel removeable, which I did).

I used melamine panels, cut slightly larger (10 - 20mm) than the panel I was veneering (I veneered the speaker with it already built up). I used Titebond 3 (slightly longer open time than standard Titebond) and applied with foam roller to panel. I then placed the veneer onto the panel, flattened it out, and placed a melamine panel on top. I then placed a selection of cauls over the panel and clamped them down onto the melamine. Allowed them to dry for 1 - 2 hours before trimming with router and a spiral down cutting bit.
 
What a beautiful remarkable look! You can be proud of your work! This US $30,000 Killer is the perfect Christmas gift for yourself.
:)
Thanks! It was all worth it in the end! But I definitely wished I had my own workshop several times! Oh, and my wife also thought the same thing! :D

I'm very much enjoying them so far, just sat on the floor slightly tilted up. They sound so good! They just sound so 'correct'. But of course they do... Look at that data!

Can't wait to get them on the stands.

Very good job ! They look classic and great. Kind of more modern ATC (with better directivity patterns).

Thanks for the info. I have a set on order and am in the research phase on applying veneer. Ive done plenty of woodworking but am much more adept at making things functional than making them beautiful and have never done real wood veneers either. Will be a good warm up project before building a murphy bed which Ive been tasked with.

Enjoy the speakers and thanks for sharing!

Lovely job on the veneer work! Congratulations.

I am in the process of designing and fabricating stands for my kit (to be delivered in late January). If you have a moment, can you measure the base/top dimensions? The published one would include the front baffle and binding posts, but I would like to make the stand base the exact dimensions of the base surface of the cabinet.

Yeah, that’s exactly the type of stands I’m going for… an exact fit.

380mm x 300mm for the top plate.

Erin is just about to put out a video for his measurements on this speaker.

Will be interesting to hear your observations on it vs the Sointuva
