Efficient speaker: Zu, Tekton, Volti, Klipsch, Fleetwood?

@ladok If you are seriously looking at the Zu stuff, I would use a little caution.  As mentioned elsewhere, people either love them or hate them.  I've only heard them at shows and as much as I want to like them, I never do.  I am going to hear a pair with some really nice amplification in the next couple of weeks and am anxious to hear a pair well set up and not at a show.  Hope I hear what everyone loves about them.  The moral of the story is to make sure you hear these before taking the plunge on them.

For a large room if you have corners available Corner Horns are fantastic and on the used market a real steal.  The other bonus is they are out of your living space but fill the whole room with sound.  If you want more Volti has a driver / crossover update that makes them supposedly better.  I bought a pair on the cheap thinking I would perform the update but after I got them in the room I can't convince myself that the extra money is required.

Greg at Volti used to do a little demo that was based on his work fixing older KHorns.  He would just speak through one of the KHorn assemblies and then speak through one of his versions.  It was a pretty startling comparison, the original sounded like his voice was coming out of a tunnel while his improved version sounds like his voice.  I owned a pair of Forte IIIs and actually traded them to Greg as part of my original purchase of the Razz.  He likes the Forte IIIs, as did I--but the Razz are clearly better and the Rivals are better yet.

That said, think the corner horns are really cool if you have the room set up and the space for them, but I imagine lots of folks don't.  I've got some big spaces in my home, but not two corners that would work in any room big enough to accommodate them--at least not if I want to stay married! 

I’m a ZU Omen Def owner for the past 10 years and love them. I will buy from ZU again. However, the thing about buying speakers without listening is that it is a pain to return ship the big heavy boxes. Free return shipping or not. I have actually read where people have talked themselves into liking components only to not bother with returning. Although I am a ZU fan, if you already like the Devore’s sound, you may just want to move up their line to play it safe. Or at least choose from what dealer's have in your area
