I think your reasons and initial impressions are fair.
I own a set, and I think they are a laid back speaker. I’m really not getting much, if any, of that in your face sound that I thought would come from this speaker (or a typical horn). My ears are about 10-11 ft from the plane of the horns.
The sound beam or directivity of it you may notice that to be a bit different from other non-hornloaded speakers. I have them on a slight toe-in. I tried them all the way on axis and surprisingly the tonality is incredibly warm in my room but of course the stage will be compromised a bit. But almost all speakers that I had in the past in the same room exhibited a compromise in the stage with on axis toe-in. The Devilles still kept a strong vocal presence, however.
For me personally, I am finding very little it does wrong...the bass extension and bass loading in the room is great. All the frequencies that the horn is supposed to play I also find on point (though my ears are sensitive in the region of 800-1.2k but I’m going to put that on the room/reflections, for now ;), though, again maybe a slight, very slight fall off from 16k and beyond... at the same time, all the things it does right, it just does right...but the slight caveat is of those things that are right, they aren’t being excelled beyond what I am expecting, if I am saying that correctly. (Whether my expectations are driven by its asking $, marketing or public outcry. Though they could be driven by my past experiences with other horn loaded devices/speakers) Again, thats my expectation and others may not agree and they will strongly disagree with me, :)
It’s not a perfect speaker - its an overall solid performer imo. I have a bigger first impressions of them in another thread here, you can search if you like. (There are a few floating around)
Long story short..if one is looking for a speaker that plays music without adding too much flavor, and exhibits great dynamics that doesnt take up too much space, then this is a really good candidate for consideration. Snatch them up on the second hand market should you ever find one.
At the time of this writing, I have them paired with a gryphon diablo 120, dual REL carbon specials, Lumin X1, DNM solid core w/ zrtn network speaker cable. Tbh, I can probably spice them up with some silver speaker cable. Also barely any acoustic treatment in the room.
