ELAC - Adante... what’s the verdict?

Here is a review. They are already showing up in the barely used market.

I’m really curious to see how the Argo speakers sound, because right now there is just no synergy or house sound with ELAC. Each line has almost noting in common looks/sound wise.

I agree. The UB5 was created to undercut the LS50, which it has. 

The Adante wants to be a budget Reference 1, but it appears to be voiced to excel in a Best Buy/Magnolia Hifi showroom next to B&W 705s. 

ELAC is not really a big enough brand in the US to be able to rely on a house sound to sell speakers. Their strategy seems to be to attack the front runners by undercutting and borrowing from their designs. 

OK, so let's ditch the Elac and go back to thinking about some of the Ryan floorstanders as a possible alternative.

The Ryan 610 is about the same size. Great bass, also a bit analytical...not a coax though so imaging won’t be as good. I would say KEF would offer the closest alternatives.

If memory serves, AJ swapped out the metal dome tweeter that was in the show prototype. 

Coaxial drivers are very rare birds in hifi. My guess is that they are very difficult to get right. They are going to image better of course, but at the expense of what?  

In the testing, it was noted the speaker demonstrating a flare at 5-6khz, which would certainly correlate with what has mentioned. The LS50 is also a very extended design and does display an elevated treble response. But if comparing the LS50 and R300, the LS50 will no doubt sound brighter due to its response curve and the lack of balance in bass.

Some other reviews also noted the R300 integration not being quite whole between the drive units, and in specific the bass to mids. Haven't heard the Adante, but the very first measurements show a bit of flare from 8-12khz. Enough that it will likely be a bit airy sounding on good recordings but hot recordings won't be so enamored.

Are the rising treble responses due to the tweeter living inside of the midrange? 

I'm not surprised at all jayctoy. My cable risers are the backbone of my system. ;-)
