Tekton Double Impacts

@charles1dad    
Calling it an attack was probably going to far. But there has been innuendo that I am sniping the company, too lazy to put the effort into audition the speaker in my own home, and that I am just being difficult. That is not the case. I just want an opportunity to hear them first. Zu Audio is a perfect example. Many people swear by them on this very site. They have a return policy also. Fortunately for me, I have heard them probably a half dozen times or so at shows. I have never once heard them sound good to me despite what others say about them. I am thankful for the opportunity to have heard them and to be able to rule them out because I was very interested in them. The audition of the Pendragons that I mentioned above was extended and at an owners home, not at a show. It was a couple of years ago. Good in some ways, but I heard some issues. That is why I want to hear the DI before I do anything.

Thanks, I did not see them on the exhibitor listing. I will check them out.

csmgolf,
Point made.  I agree that there are some speakers you might hear at a show and you know pretty quickly this is not the speaker for you.  In that case, shows can be effective at narrowing the field.  Now if you hear several you really like......well, that's where the home edition is critical for me.
Many owners of the DI/SE's find them full range, no sub needed.  With large scale works, I do not.  I use a pair of subs that really fill in from 20-30hz.  So take the 20hz spec with a grain of salt.  Many rooms will not achieve anything below 30hz.  But for many, that is irrelevant depending on musical preference. 

@csmgolf 10/4 on the Zu. Not sure what sells them. Hard to find a speaker that measures worse than it sounds and still finds a market. 

csmgolf,
Believe me I understand your position on  hearing speakers of interest at shows. This does act to a certain degree as a screening process and is better than no exposure at all.  My point is that if there is very serious interest in definitively judging a speaker home audition is the undisputed best option. 

Regarding Zu speakers my listening impressions at audio shows (4 separate occasions) have been the same disappointing result. 
Just unimpressed. Each occasion was the same.  Very loud rock music and driven with solid state amplifiers, outcome= poor sound quality.  Perhaps I needed to hear them with acoustic jazz at reasonable volume levels driven by a good tube (or solid state) amplifier,  who knows?
