Tekton Design Moab

Ordered a pair just now. In Dark Gray, to which Tammy immediately said, "Oh the Charcoal is beautiful!" Charcoal sounds better than Dark Gray (even though we are talking about the same color!) so Charcoal it is!  

My beloved Talon Khorus do still sound awfully good. It will be interesting to see how the Moabs stock out of the box compare with these tweaked and modded warhorses. Both the strength, and the weakness, of the Khorus is using the 10" woofer to cover so much midrange. Its a strength because it makes for a very smooth and cohesive sound. But its a weakness because its asking a lot of such a large driver to go so high. Talon makes up for it with their isobaric design. Mounted inside and directly behind the woofer is another identical driver facing the opposite direction. The idea is this relieves the front facing driver of having to compress the air inside the cabinet. This does allow for a much faster response, and is a big reason for the wonderful music the Khorus produces. 

I have a feeling however it is no match for Eric Alexander's ultra-low mass driver array solution. Only one way to know for sure. So we will just have to see!

John Strohbeen of Ohm Acoustics is also a musician and speaker designer. He says he tunes his speakers to sound like what he hears in prime seating at Carnegie Hall. Having been to Carnegie Hall, I think he in fact does a very good job.

Taps off amps for different impedance is not about volume. It is about damping factor which may produce different distortion levels or characteristics. A higher impedance tap will tend to control the speaker transducers less loosening up the sound possibly with more distortion if damping factor is not above a certain level. It also depends on speaker design and will vary with that as well. 

Lower impedance taps will tend to control drivers better and lean towards lower distortion. Which sounds better? Only way to know is to try but technically lower amp output impedance and higher damping factor will tend to be more accurate
There is a lot that goes into it. Roger Modjeski always felt his amps benefited from light loading, using a lower tap on the amp than the rated speaker impedance. Less distortion, more damping, less stress on the tubes and the amp overall. When it came down to it though he told people to use the tap that sounds best to them.

On occasion I use Atma-Sphere M60s with my many panel speakers. With one exception, I put a pair of Speltz autoformers in between the amps and speakers. It is very easy to hear the difference as you adjust the impedance ratio on the autoformers.

Yes it is about damping factor but it is also about gain and feedback. As I mentioned previously, there is a lot that goes into it. When I look into various speakers I always find that talking to the speaker designer is quite beneficial. You can tell a lot about the design of a speaker based on what amplifier was used in the testing.
True volume is part of it but should not be the only focus.
