Andrew Jones Returns with Jones and Cerreta Speakers: New Troubadour to Debut at AXPONA 2026

Andrew Jones to debut Jones and Cerreta Troubadour at AXPONA 2026 with MoFi Distribution but what is this field coil concentric floorstander and how much will it cost?

I don't think it looks much better than my old big box Pioneer speakers and won't sound any better than any other good sounding speakers.

you mean the ones with the vinyl veneer ? LMAO .............

I don't know if it was vinyl veneer. It looked like wood veneer with the 15" woofer and 1" tweeter.

Andrew Jones has a good track record, with his coaxial speakers.

Now that systems are used with video as well as audio, which means human speech will be reproduced much more often than prior to this AV era.

In my view coaxial designs are going to excel in the reproduction of human speech, and are in many ways ideal for AV systems.

I chose SEAS coaxials which are made by SEAS under license from KEF for my AV room center, in my TL design. It is an absolutely superb center speaker, and actually just a really good speaker.

However, as Paul Klipsch pointed out years ago, there is the problem of equal reflection from around the main cone. This is going to result in some cancellation. Good design can minimize it, but it will surface to some degree. In my case there was a dip at 9 KHz, which was only just audible, but bugged me.

You can see the same issue in this KEF meta speaker.

That is very similar to what I encountered, but I recall my dip was slightly more pronounced. I have two of those coaxials in my center. Originally only the bass cone was used in the upper driver, as a fill driver for the variable BSC.

This bugged my so I designed a system that provided an Eq signal to the upper driver. I was not optimistic, but it worked like a charm. Sometimes you get lucky.

So it will be interesting to see what the FR of this driver looks like.

Going back to energized magnets like they did pre WWII is strange. As the speakers need to be plugged in to energize the speaker magnets, I would have thought it to be sensible just to make them active speakers.

It will be interesting to see how these measure.

Why do KEF meta Q Series use 3/4” tweeters ?
4” mids is smaller than r Series but fine for a budget line.
Do they struggle near reference level or above it ,??

 

[Eppie]

Beat me to it. I watched Jana's video last night and he explains the design philosophy very well.

 

[Mikado463]

did I miss it ? do we know a price yet ?

I hope to see and hear this speaker 'in the flesh' some day......

Actually, 3/4" tweeters are optimal. There are not nearly enough of them and less than there used to be.

The reaons is that the smaller diameter tweeters don't start to beam until a significantly higher frequency.

My rear backs use 3/4" tweeters the old Dynaudio 21 AFs, crossed at 5 KHz and the center in our in our inwall system uses an Eaton 3/4" dome crossed at 4 KHz.

Here is a SEAS 3/4" dome that has good dispersion to 10 KHz

Here is a very high end SEAS 1" dome I use in my front dual TLs. Dispersion is starting to limit at 7K Hz. In that design I have to cross at 3.5KHz because of power limitations. To use a 3/4" dome effectively requires a really good mid range driver and there are very few of them, and actually less than there used to be. For reference speakers only Volt UK, make a really good dome the can be crossed at 4 KHz.

Who knew , I recal someone on Avs claiming the KEF meta Q Series can’t handle reference level ? But I was skeptical..

Reference level is anything you want it to be pretty much. I have heard Squishman's KEF speakers and they play quite loud enough for his environment.

As far as I'm concerned if a system can reach concert level with head room, I am happy. I don't mean bleeding loud rock concert levels, but concerts with natural instruments. Although when you add a large organ on top, that can be pretty loud. But I have never run out of headroom with my rig.

Yeah I’d need an actual spl meter to see how high I’m going but the sound meter app says I was getting 95 db peaks , and that was at 70db levels . it’s probably higher during movies .
But since I like how these speakers and my big sub sounds , I’ll save $$$ til something breaks . I got another cheaper setup upstairs too .
If my tv breaks maybe i should use my little 40” lcd ? Not sure yet . But its inputs are going Bad..

I think this is one insanely cool speaker

I never heard of "field coil" before

I had but only from Audio Note and some other what I would call niche companies. I have never heard that type of speaker but seems overly fussy or others would be doing it.

Draws 60 watts to power the field coils of both speakers ....

Before WW II and the development of more powerful permanent magnets, energized magnets were very common if not the rule.

As a child I was given a 1938 HMV radiogram, and that had a mains energized elliptical speaker, that also acted as the inductor for the power supply. I connected a 12" old Goodmans speaker to the external speaker connections, and that was not a lot better. So that started me building speakers and have used my own speakers ever since.

Gilberb Briggs, founder of wharfedale, published a lot of books for the DIY constructor. He told me that it was more profitable back then to sell raw drivers then complete speakers.

It is a real pity that speaker builder is now rare among audio enthusiasts.
