1/4" - 20 I think a 1 inch or 3/4 inch length is best, but I believe there are folks who have used slightly longer lengths. |
@delta77 Just looked up Rosso Folgore. Matches your Maserati? |
@radiohead99 Depends on which models you are considering. If you don't get any direct responses from owners in your area, (and you are looking at the DIs or above) reach out to Clement Perry of Stereotimes via email. He may be able to help. He knows a few Tekton owners in the NJ/NYC area.
All the best. |
@radiohead99 Any updates? |
The ’experiment’ with Scott Sheaffer’s Found-Music 2A3 amp driving the Tekton SEs has blown all of my pre-expectations to smithereens!
I want to THANK Charles @charles1dad for being steadfast in his encouragement and support as I considered SET tube amplification options a few months ago. There are others who have also been helping me through my recent audio journeys, and I will thank them personally and more directly, once I pull together a mini-review of sorts.
There has been discussion of low watt SET amps (perhaps) ’not’ being the ’best’ choice --- on TJ’s, now very active and insightful, Perfect SET speaker thread. I beg to differ, respectfully.
I am getting (read, fantastic) full range, high volume, superb sound quality results with a 3.5~4 Watt amp that was custom built for an 8 Ohm speaker, with an optimal impedance pairing range of 6 to 9 Ohms...
AND THIS ON the Tekton SEs which are a 4 way 4 Ohm speaker with 7 array tweeters, 2 mid-range drivers and 2 bass woofers, per speaker.
I’d also like to remind everyone that I am also driving the SEs with the T+A PA 3100 HV integrated amp which is designed as a near zero negative feedback high voltage amplifier.
The T+A PA 3100 HV outputs 500 Watts into 4 Ohms RMS (per channel) AND has a peak output of 700 Watts into 4 Ohms (as provided by T+A’s specs).
Two very, very different amplification chains. Both with supremely satisfying results.
[Note: I am using the fully balanced Grandinote Genesi Preamplifier ahead of the Found-Music 2A3, with custom Cardas XLR adaptors, to allow for SE IC connection]
|
Another update. I acquired the Found-Music 2A3 monos and the Grandinote Genesi preamp with the goal of a 'second' system (same room) but with different amplification chains and two sets of very different speaker types.
I recently brought in the Cube Audio (Poland) Nenuphar single-driver speakers as a possible solution for the Grandinote > Found-Music pairing. After 200 hours of runtime on the speakers, I conducted a lengthy A/B between the SEs and the Nenuphars with exactly the same system chain (refer to my post above).
The SEs are clearly the better one-speaker solution, and were superior in a few areas....however, for my needs and my preferences I find the Nenuphar to be a much better fit.
The Nenuphar is a 'focused' solution but what it does well, it does exceptionally well and checks off on what I have been looking for with regards the Grandinote/Found-Music amplification chain. As you can tell from the post above, the SEs also shine with this amplification chain.
The question now is whether to keep the SEs or to upgrade to a different Full Range speaker to pair with the T+A PA 3100 HV integrated amp.
Based on listening to Ezra's @audioezra Ulfberth BEs driven by Bricasti M28s...it is one of the speakers at the top of my list. Based on feedback from Allen @aolprodj and Mike Kay of Audio Archon, Ezra's system kicked up to another level when he replaced his then front end with the Bricasti M12, also feeding the Bricasti M28s.
For those of you with experience with the Ulfberths and / or the Encores, or with something else Eric is most certainly working on, let me know your thoughts. Thanks.
|
@corelli Wish I was going. Should be a terrific show. I keep hearing great feedback about the new location. It will be interesting to get your take, as well as that of others, on whether the rooms present better than at the previous location.
I know Allen will be there. Mike Kay / Audio Archon should be in attendance. Teajay?
|
The pricing reflects the forward motion of Eric’s business model and his maturing product line / cost structure. In my opinion, this is normal and ultimately beneficial to those purchasing his speakers. Trickle down and reduced costs for fantastic sound performance...I’ll take that!
He is also smart to price and list his products in the basic finishes first. For example, this reflects a $1K discount on his SE model. 4.5K looks much more attractive (perceptually) than 5.5K, for the lovely automotive paint finishes.
|
Please understand, I'm also in the same position. I'll likely be listing my SEs and moving up the Tekton line or to another speaker brand, the Horning Hybrid Eufrodite Ellipses Mk3 being at the top of my list as an alternative.
I would have loved to have had the price remain steady at 6.5K but in this case, that's the way the apple has rolled.
The Double Impact BEs have taken the product position that the SEs formerly occupied.
@laaudionut Please delete the section of your post that addresses me inaccurately, since it clearly (due to grammar) implies I have 'your "finger" take' on this. Feel free to reword it to reflect your position [Not mine]. I'm fine with your position on this, so it's not about that. Thanks and all the best with your listings!!!
|
@laaudionut Thank You! Much Appreciated. |
FYI Tekton Design Moab is listed as up for review by Terry London at 6Moons. |
The Tekton Design Double Impacts will work in your room. Those who have the Impact Monitors / Pendragons are in a much better position to advise with respect to those two speakers and room size...however, I believe all will work fine with your room. |
@mac48025 +1 on your statement: The SE’s have motivated me to upgrade my system to get the most they have to offer. I would not be where I am system enjoyment wise without the DIs and SEs over the past two years. Thanks for your help and guidance along the way. +1 @gaal The more I fine tune my system...the better appreciation I have for the capabilities of the DIs. |
Not surprising or unexpected once the Double Impact BE was released. |
It’s listed in the Double Impact page as an upgrade option. |
Tekton Design / Eric Alexander has started posting YouTube Videos of his speakers, etc. Take a look/listen on the Tekton Design website. |
@timwelborn Which specific speaker, for the comparison of the BE vs standard tweeters? I have heard both versions of the Ulfberths. Should you be interested in differences between the standard and BE version of the Ulfberths, PM me. |
Hi Tim. This goes back 6 months, so things may have changed. I was very keen on upgrading my SE speaker tweeter array to a BE array, after hearing the Ulfberth BEs. At that time, Eric said it wasn’t possible (SE specific). You may want to check with him. Plus, he should be in the best position to describe the differences between the standard and BE tweeter array.
Let us know what you find out! |
@bstatmeister Congratulations on your successful audition!!! : )
@smodtactical I believe @audioezra ’s room is very close to the dimensions of your room and his Ulfberth BEs sounded wonderful (and continue to). And yes, they will "best" the DIs. |
@holley Thank you for your comprehensive, thorough and detailed comparison and impressions of both speakers. These comparisons are tough to do and time consuming, as are the write-ups. Thanks also for taking the time and effort and for sharing your findings!!! |
@jaytor The Double Impacts have a large (3D area) ’sweet spot’ for listening positions. The DI-SEs even more so than the DIs. A performance attribute I loved about the SEs.
I worked with the SEs more extensively (to get them ’dialed’ in) so the same may be true for the DI base versions.
So I disagree with the PF "findings’ on off-axis response you point out in your post.
This is an area and feature/benefit of the DIs/DI-SEs that is superior to my Cube Audio Nenuphars.
I cannot comment on the Moab as I have not heard them. All Ulfberths (3) that I have heard had a large ’sweet’ spot (in other folks’ systems and rooms). The double tweeter array may behave differently than the single array.
@teajay would be a great resource on this.
FWIW: My room is 19 ft (front wall) by 26 ft by 9ft. Very close in size to yours. And I also (at times) sat 12 feet from the speaker plane. |
@sathtom Do you own the McIntosh MA252 or are you considering it? |
@sathtom Thanks. I did a quick read up on the amp and it will work fine in terms of powering the DIs.
I, of course, do not know your preferences however (for my sensitivities) I would look to pair it with the DI-BE version or the SEs, which can be had used at reasonable prices. I say this because the MA252 / DI is more of a like-like pairing. The BE version or the SEs with the MA252 will likely be more balanced. Again, my opinion. |
+1 to @jcarcopo 's entire post above.
|
@graitscott The Double Impacts are great for low volume listening. How do the Double Impacts hold up at lower volumes? There is no substitute for an extended audition of speakers in your own room and with your gear. Tekton offers a trial period. It’s the ideal and best way to go forward with any speaker choice. Whichever speaker you choose, you will have to make some adjustments in the gear and cables, etc. to bring them to where you want them to be, for you. |
@adversam I used my Pass XA 30.8 amp to power both the DIs and the DI-SEs. It was a good match and pairing.
The XA 25 is an excellent choice.
The Van Alstine may also be a good choice, but I do not have direct experience with it.
All the best with your decisions and final choice. |
@adversam I did not use subwoofers. So just the XA 30.8 powering the DIs and the DI-SEs.
I also powered the DI-SEs with my 2A3 monoblocks and preferred them over my solid state amps, including the 30.8 and the T+A PA 3100 HV. However, more power and especially high current amplification like the T+A has it’s advantages and upsides.
Average SPLs at the listening position were typically in the high 70s / low 80s dB range, music dependant; with swings into the low to mid 90 dB range.
My room is on the large side [19 by 26] and the Tetktons were pulled out into the room.
|
@adversam Happy to help! The Preamp was the Pass XP 20. |
@morg111 Marc, it comes down to your reference(s) of sound quality and how your system comes together to achieve that. I looked through at least 60-70 percent of this 112 page DI thread. Felt like somewhere I’d find an answer to what amp preamp these DI speakers need. What I found was that the DI’s benefit having tubes either in the preamp or amp stage.
Is that now considered set in stone, they need so much warmth to sound their best that tubes must enter the picture??? I recommend following quality, whether tube or solid state amplification. +1 to @ozzy62 ’s post addressing the "warmth" issue you brought up: Tubes need not always be associated with “warmth”. Looking forward to learning what you choose. All the best in your search and choice. |
