Tekton Double Impacts

articdeth,

That's a unusual name could you elaborate.

Here is a more detailed description of the DI's that may help you understand the design a little better.

Even though these are tweeter transducers the six of them that form the circle, based on what frequencies they handle, radiate acoustically as if they were one six inch mid-range driver.  The transducer in the middle is being used as a tweeter and handles the high end frequencies up to 30Khz.  So, acoustically you have a six inch mid-range driver with a coaxial mounted tweeter which means it functions as a single point source.  Now, by Eric figuring out how to make this work you get all the advantages of a coaxial driver, however the mid-range array weighs close to nothing leading to blazing speed/dynamics/micro-details compared to a regular six inch driver, regardless of what materials it is made out of it cannot be as light in weight.  Yet, you still get not only remarkable transit response, but great control because each driver is small and well behaved.  The closet you could come to this regarding weight/control would be a ribbon or AMT which cannot be used as a coaxial design as a single point source.  Brilliant on his part!

The more I listen to the DI's regarding mid-range and high frequencies they easily rival any panel design/ribbon/AMT I have had in my system and surpass them in low end extension/dynamics and overall macro-dynamics.

Hi Kdude,

I just did some checking on the Truth. Arthur Salvatore has a long write up on it in his recommended components.

I have to admit I am confused by your comment that " some of the guys build the Truth pre amp with 6 to 10 db of gain." Are you referencing the Hornshoppe Truth?

As far as the volume knob, I am under the impression that all Hornshoppe Truths real listening levels is between 1 and 2 o'clock, which is maximum rotation. Perhaps another owner can chime in on that point.

Just now I noticed on A. Salvatore that he stated the Truth actually losses .5db. I sure didn't know that.

He also talks about it use of light as an attenuator.

Also something unique about the solid state that's used for the buffer is mentioned, but I did not focus on that part of the write up at all.

My educated guess now is that for my needs I believe the combo Truth, Triode Labs, and Electrons will probably satisfy my needs. But it comes at risk for me. No audition, no returns, and not a lot of margin for error. I need to figure a more comfortable way to proceed, especially since I do not sell on line as of yet, and no guarantees that I ever will.

If I understood Almarg thinking on this matter, he would opt for more power to guarantee a full performance under all musical circumstances.

Hi LP,
Keep in mind that Al’s litmus test is minimally compressed large scale symphonic music capable of peaks of   105 db at his sitting position 10 feet away. He knows the sensitivity of his speakers and then calculates the power needed to achieve this without strain or clipping.

My listening requirements are less demanding than Al’s and I can get by very happily with less power than would satisfy him. We’re both quite content with our respective audio systems. The key to success is truly determining what you ultimate objective is. Power requirements   (and Listening volume levels) obviously vary amongst different individuals.

LP,
Yes I'm referring to the horn shoppe "Truth" preamp,
It looks like from what I read on their forums that some guys are modifying their Truth preamps and adding Active gain and or transformer based Impedance buffers,possibly like a autoformer.

I read through all these posts again and analyzed all the specs again and I still come to the conclusion that this pairing in gear might work ok for you in a smaller room and being close to your speakers.

Now if you listen to symphonic classical and like it loud then I also would agree with Al and say that this pairing in gear wouldn't work without more amplifier pwr,probably at least 25 watts or more.

Even though I really like the 1 watt from the MZ2S with my DI's playing easier music,more pwr is needed to play more complex and dynamic music.

I hope this helps you,
Kenny.

Kenny, thanks for the detailed post on the driver array and how it works. From an earlier post of yours:

"So, acoustically you have a six inch mid-range driver with a coaxial mounted tweeter which means it functions as a single point source."

I understand the single point source concept, however I don't see how that would work when doubled up as it is with the Ulfberths. Can you explain?

Thanks.
