I have had the Tekton Moabs with BE tweeter and upgraded crossover for about 7 months. I think they are fabulous speakers, especially for the money. I also have a pair of Magnepan 3.7's set up in a second room. The ribbon tweeters in the 3.7's do create a better top end with more air but I prefer the Moabs in every other way and do almost all of my listening on them. I have directly compared the Moabs to the Pure Audio Project Trio 15 horns, Spatial Audio M1's, Emerald Physic CS2's, Vandersteen 2Ce's, Magnepan 1.7's, Zu Audio Omen's, and KEF LS50s among others. None of them comes anywhere close. I have not had the opportunity to listen to truly high end speakers, much less buy and compare them to the Moabs in my own home.
For whatever reason, the Tekton Speakers attract haters and devotees in about equal measure. Almost without exception, the people that own Tektons are happy, and the people that own Moabs are ecstatic. I think it is notable that Jay's Audio Lab auditioned the Tekton Ulfberht's on his YouTube channel with generally positive comments. His current speakers are $170,000 Magico M6's! BUT, I do think that people who claim the Moabs are equal to speakers costing 10x as much probably have no basis for saying that. Since I am able to compare the Moabs with the Magnepan 3.7s whenever I want I can tell you there is plenty of room for improvement in the Moabs. My perfect speaker would combine the incredible detail and treble response the 3.7's offer with the stunning soundstage, great dynamics, terrific bass, and rich involving sound the Moabs have. What I can't tell you is what that perfect speaker is or how much it would cost!
The Moabs also work well with every kind of amp ranging from the flea watt Dennis Had SET amps on up to the 700 watt PS Audio M700's. I have built 4 First Watt DIY amps and the Moabs are very revealing of the differences between them which is a huge positive.
Bottom line is I would recommend the Moabs without reservation.
