I just found this new Zellaton forum. I would like to know what is the significant benefits of the Reference Ultra at about $200K more than the Plural Evo, other than it appears to have more woofers; hence, deeper and fuller bass. I assume you or someone on this forum has heard them both and can comment.
I have heard the Stage Ultra, Reference Ultra, and Plural Evo, though unfortunately not all in the same room. I haven't heard the 'Klassiks', but I would love to listen to them somewhere.
My impression is that the core of Zellaton's design philosophy and architecture is the use of a proprietary high-tech sandwich single broadband cone for the majority of the frequency range, complemented by a tweeter for the highest frequencies (although in a previous model, Studio Reference, the broadband cone extended up to 20kHz and lacked a tweeter) and a '(sub)woofer' below. The combination of the advanced (sandwich) driver and the absence of a crossover in the most critical range for human hearing creates a lot of 'the magic.' This applies to all Zellatons as far as I know and largely defines the 'house sound.'
The EVO line contains some 'compromises' compared to the Ultra. To my knowledge, most noteworthy are ..
- The sandwich cone construction of the broadband and bass cones has been adapted and made suitable for more mechanical manufacturing instead of everything being handmade.
- The tweeter is a 'conventional' dome, instead of Zellaton's proprietary sandwich.
- The cabinet's (finish) quality. 'Downgrade' from Bugatti (bizarre, drool-worthy) to Mercedes (plain fantastic).
Additionally, the bass of the Evos is reflex loaded instead of semi-open baffle, but with the same sandwich cone material as the broadband. This was done intentionally with the motive of integration into smaller spaces.
Personally, I think that last point (room integration) likely has most impact on the listening experience.
I haven't heard the PE and Ultras in the same room, but I didn't get the impression of a loss of homogeneity due to the PE dome tweeter (my ears are 54 years old). I found the bass of the PE (in the respective case/room) to have more punch and fun factor than the Stage Ultra (in a larger room). It is - as often - quite context-sensitive. I don't rule out that there are people who, in a certain context, setting, complementing gear and room, will prefer the PE over the Ultra... I guess that in a good and sufficiently large dedicated listening room, with some exceptional gear, the Ultras will go a step further in several parameters. I do think that the PE is the likely sweet spot in the range and probably also the "bread & butter" for Zellaton. Ergo: numbers and value for money.
I haven't heard the smaller Emotion EVO. In images, the broadband sandwich mid/woofer in that speaker doesn't 'breathe' to the back (back seems closed) and is therefore (I assume) ported, just like the PE woofers. I wonder what that does to the speaker's signature..
Anyone heard it, compared to the PE?
Congrats Steve! Good luck 'howling' them up the stairs....
