MUNCHEN 2025 MOC / MARRIOTT The final Chapter !

The Vyger system sounded a bit strident to me, especially in the treble, probably not helped by being played too loud IMO.

Could the combination of an extremely stiff, ultra-low density tweeter dome material with significantly less rigid and much higher density PP cones perhaps also play a role here? ;)

Regarding beryllium (again).
Emphasis are mine.

It's about the speed of sound through materials in general and about inherent damping properties.
At a deeper level (subdomain #1) there are the reciprocal effects between, in this case, the dome itself and the suspension.

Beryllium is theoretically the ultimate material for the reproduction of mid and high frequencies, because of the speed of sound (approx. 12,890 m/s) and the associated properties including high stiffness and low mass.
And herein lies the issue. Simply put, Beryllium is actually too good for a natural reproduction of HF sound.
The difference between the material properties of a Beryllium dome and almost all cone materials is so great that it's almost impossible to achieve a sonically homogeneous whole.

This phenomenon was noticeable in almost all systems that I have listened to with a Be HF unit; an obvious disjunction between the highs and the low/mid band.
Would you say that a tweeter/midrange, coaxial: 3.5cm beryllium dome / 14cm magnesium found in the TAD CE1TX sufficiently diminishes the "difference between the material properties" (Be vs Mg here), so that TAD's CST (Coherent Source Transducer) driver is "sufficiently coherent" (the coaxial CST found on the biggest model, TAD-R1, is made of beryllium for both tweeter and midrange).

On the CE1TX, magnesium (for the midrange) may not be beryllium, but it is by no means polypropylene either (used in the Vyger's midrange); it's surely incomparably stiffer than polypropylene.

I own a lovely pair of Harbeth M30.2 Anniversary in a second system. Very-good-but-not-outstanding textile done tweeter, and "Radial 2" midrange cone (Radial 2 is a polymer, not exactly polypropylene AFAIK). Coherent speakers indeed, but limited.
I found the TAD CE1TX with their Be/Mg CST tweeter/midrange coax driver both much less limited, and coherent. @D.Duttilleux
Do you disagree ? What do you think about this Be/Mg coax ? (feel free to be direct, I'm from Northern Europe ;-)

I haven't listened to the TAD CE1TX, but it's praised for its "pinpoint localization of sound images with three-dimension-like sound-field".
This isn't surprising given the point source characteristics of such small coaxial drivers.
TAD has undoubtedly made sure that the 7" woofer with aramid composite cone is well integrated, which shouldn't be too difficult, since it only covers the bottom 3 octaves.

I did listen to the Grimm LS1Be, which (also) uses a Be dome + SEAS W18 woofer with magnesium cone.
To be honest, I wasn't impressed. I m sure it's a fine system for studio work, but it didn't sound natural (enough) and the incoherence between tweeter, mid and (separate) subwoofer was clearly noticeable.

Many audiophile clichés lack technical substantiation, which makes many, if not most, reviews rather useless and redundant.
Loudspeakers that sound quite different - in some respects, are often described in similar terms.

Sometimes it's even more insightful if the reviewer – provided he knows a thing or two about music – limits himself to describing the experience and his feelings.

That said, what Matthias means by 'flesh and bones' can also be referred to as 'body'.
 
Interesting that JV chose a digitally sourced system as his best in show (cost considered), would like to hear that Voxativ streamer DAC:

 
What do you think this system sounds like, just looking at it?

I think 'never mind'.
 
They sound really good actually, but not a wow or jaw dropping moment for me. Simply because I am in favour of completely different presentation compared to what Voxativ is doing.

When you placed the ripolbass in the room good, you have few problems with roommodes. I'm not a big fan of the Lowther principle with a buzzer cone. Mostly frequencies above 2 kHz require damping or a good phase plug.

Btw, there's no lack of 'body' in the 9.88 system (rather too much), but it's overshadowed by a lack of coherence.

In terms of coherence, this showed more potential, but the room was too small.
Provided you can live with the typical shortcomings of the full rangers and OBs in general.

'Wow' and 'jaw dropping' can be deceiving imho.

- If these two indicate 'fireworks' or 'spectacular characteristics' (that stand out), I'd be cautious. It's what many high end setups evoke.
- If you are talking about 'rightness' (naturalness), something that can be experienced instantly but is usually quite subtle, then there's potential.

Actually this’s so subjective that my wow and jaw dropping stuff could be very different to everyone else.

It’s hard to describe how they sound, especially under show conditions. But given I had decent time at the show, I spent 15 minutes each room and listened to a few tracks to form an idea about how an overall system sounds, particularly the speakers as they’re at the end of the chain.

As voxativ using drivers like no other brands, they do have their own sound characteristics. But somehow I don’t see the massive entertainment or engaging feelings like I have had with the others.

Probably the room, music etc. that did not reveal the full potential of the system, especially the speakers when I was there which is not surprising and easy to understand. But so far, my limited experience with them is just that :)
 
Indeed, I could have mentioned personal preference - as I did before, but that seems superfluous, since this forum exists to share personal experiences and opinions.
