Tekton Double Impacts

@david_ten - My listening room which is dedicated place for DIs is getting ready and will be done in next couple of weeks, for now I’ve placed DIs in main floor and its playing as-is without much fine tuning to the system, this is just to avoid rework of calibrating the system again in its dedicated room.

I must say even without much tuning to system/room acoustics the DIs are quite dynamic even at low/mid levels with much clarity which I never experienced earlier. Now I wonder how better a speaker (DIs) will sound after calibrating the system/room acoustics and how it will sound with an Analog system.

Just waiting for the work to be completed and meanwhile enjoying DIs as-is !

Iamasif,

the di's will improve with and every improvement made to components or room. Making a dedicated listening room really showed off what my DI's can do. As good as your DI's sound now, you'll be very pleased hearing them in your new room once you get them positioned properly and the room treated correctly. With all the bass they can put out I found installing floor to ceiling bass traps in each corner to be very beneficial. Good luck getting your room finished and take a towel with you to wipe off the ear to ear grin you'll have on your face when hearing them in it :)

teajay, 

i dont know if I'll ever be able to afford the Ulfberhts but I very much look forward to your review of them. As good as the DI's are, and I find it difficult to believe anything could be a lot better, I believe the Ulfberhts are going to blow your mind. You were honored being the first person to review the DI's and Ulfberhts just as I was to own the first pair of DI's made.....wish I could say the same regarding the Ulfberhts!

i recieve my TungSol round plates and KenRad 12SN7's along with the 40's Mullard 12AT7's next Tuesday. I can't wait to try them in the MZ2 and share the results here. I'm sure I'll eventually get the Triode Labs 2A3 SET but I'm having too much fun driving the DI's with MZ2 right now. What a bargain combo....the $2k MZ2 with the $3k DI's........just add a source and you have audio nirvana! Thanks for the heads up on using the MZ2 as an integrated amp with the DI's..

It just occurred to me that the very first speaker I purchased as a junior in high school, with my life savings, was a set of Micro Acoustic speakers with a 5 tweeter array back in 1978-79. I loved the big and open sound! I purchased them at Tech HiFi after listening many, many times at the Nashua, NH store location.

I remember my set having a 5 tweeter array, but this picture shows a 4 tweeter array I think? You could also adjust the tweeter output level. Good idea for Eric.

I bet Eric was inspired by the same speaker!

Hi grannyring,

I'm glad you shared your recollection of the speaker in your past using a tweeter array that you totally enjoyed.  It gives me the opportunity to clarify the misconception that the seven tweeters in the DI's are a type of line array in Eric's design.

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 weights 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 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.

Mac,

Looks like you have some very good tubes coming your way should be a very good combo.I'm anxiously awaiting my MZ2,I already have plenty of excellent tubes to roll.

The MZ2 must have one heck of a glorious single watt.

Enjoy the music,

Kenny.
