What have other owners of Tekton Design Ulfberht Speakers discovered?

Now that I have lived with the Ulfberht's for close to a year I would like to share some assumptions about them with GON members, and see what conclusions that other Ulfberht's owners have come to based on their listening experiences. 

There is no doubt in my mind that the Ulfberht's are the most lifelike and musical speaker I have ever had in my reference system.  To think that a seven foot 21 driver speaker completely disappears in a totally accurate sound-stage,  (how large or small is based on the recording) like a small two way monitor is still a remarkable feat, indeed.  Many listeners to my home find it hard to believe how cohesive they are top to bottom and speak with "one voice".  Many large speakers can do "big" power music, but sound "big" on all music.  They can also blow out of proportion the size of individual players.  Not the Ulfberht's, they present any music in a natural manner, never exaggerating anything out of proportion.  Other special qualities of this speaker is it's overall "ease/effortlessness" regardless of volume levels, thunderous dynamics, its ability to pressurize the room with deep accurate bass frequencies and a sense of "aliveness" that you find in live music.

Some guidelines to optimism the Ulfberht's performance:

1) Get them at least four feet off the front wall and two/three feet off the side walls. My dear friend Ezra has his pair in a relatively small space, yet they sound beautiful.  Still, his pair is about five feet off the front wall and two feet off the side walls. 

2) I believe in most rooms a very slight toe-in gets you the the best center image, without narrowing the width of the sound-stage at all. The center tweeter should aim just on the outside of your head at your listening position.

3) Just like all Tekton Design speakers the Ulfberht's are a conduit, anything you put into them you will hear it.  Be prepared to use the finest source and amplification to tailor the sound of your system to your personal taste.

4) Even though the Ulfberht's are an easy speaker to drive, they love high current amplifiers to get the best out of them.  Right now, I have in for review a brand new model from Coda Technologies called the Number#8, beautiful looking with blue lighted meters, which has the current capability of 150 Amperes on a peak!  Without a doubt the Coda Number#8 is a superlative amplifier, you will get all the details when I write the review for hometheaterreview.com, and might be the best amplifier that has ever driven my pair of Ulberht's.  I have have tried six highly regarded amplifiers, they are all excellent in their own right and sounded great on the Ulberht's.  However, the synergy with the Ulf's is very special in many ways.

I am emptying a storage I had from a prior home from 11 years ago. This was before I was married, and I need to have these all at one time so the wife thinks they’re from the old house, and not something I just went out and purchased, along with al lot of other equipment. I get one shot at it, and need to have them all before I finish emptying the storage. Otherwise they would already be in use.

That is why I cancelled my order a while back. Poor communication and a delivery date that was unknown. Also he wanted the money up front.
Good luck.

@speedbump,

that is hilarious although I can relate. I bring stuff in regularly but use the power of 10 rule. It costs a tenth of what I really paid for it unless I got a muthu of a deal then I’ll brag about it. 
Good luck my man!

Tekton Ulfberht Speaker Review by Dick Stein

I hope some of you will find this useful.

Hi all, I am a long time audiophile who started my journey in high school with a hand built Heathkit Receiver and a Garrard Zero 100 turntable in addition I hand built set of AR15 speakers also courtesy of Heathkit. Life after marriage and two children slowed down my hobby but did not end it, once my oldest was off to college I started to re-explore what was available owning a BK Pre-amp, Aucrus power and pre-amps, and more recently several PS Audio components. The only stand alone DAC in my system was a Topping D90 DAC which I owned for a short time. For speakers I have had several versions of Thiel’s and a set from Dayton Audio and a few others over the years. Certainly not as wide a range of products as many of you but enough to have a feel for what is possible from a sonic perspective. For my current system please see the equipment list at the bottom of this review.

After a long nine month wait, I finally received our new custom Tekton Ulfberht speakers, so now it’s time to share my observations with those interested in this Tekton set. First a little background on where I came from, I have been living with a set of upgraded Tekton double impacts for the past three years and they have been a remarkable set of speakers in my system and a great value. The DI’s were also paired with a set of Tekton Enzo subs. This combination was dynamic with good deep bass and solid mid’s however, I always felt the top end to be a little lacking. My room is large, 24 x 30 feet with 12 foot ceilings. The Ulfberht’s were my logical next step, additionally I paired them with a set of Tekton 4-10 subs which were ordered at the same time as the Ulf’s. The Ulf’s also have the beryllium tweeter upgrade (centers only) and I had ten sheets (24” x27” each) of GR RESEARCH - NO REZ installed at build time by Tekton. The no-rez greatly reduced cabinet resonate by replacing most of the normal white batting in the Ulf’s with the no-rez.  The Ulf’s also have Herbie giant gliders replacing the standard spikes. I will list my full system front end and my room details below. 

Setup and sound…

After the initial unboxing of a speaker and before break-in I must say I was a bit surprised the Ulf’s didn’t blow me away, they did however show some hints of promise of what was to come. Out of the box they were a bit drawn in and didn’t excite me they way I had hoped. The Ulf’s needed quite a long break-in (a couple hundred hours) and placement was far more important than with the Di’s. The final resting place for the Ulf’s is about 7 and a half feet from the back wall with a 20 degree toe-in. The speakers are about 12 foot apart with a main listening chair about 11-12 feet back. The 4-10 subs sit outside and back from the Ulf’s (photo below). 

So how do they sound after break-in and proper placement? After much waiting and anticipation and hours finding proper placement; they have made me a happy man. The 77”, 225 pound monoliths have disappeared, vanished! The soundstage is wide and the imaging well detailed. The highs I was slightly lacking in the DI’s is now pristine and present. I will say one observation I noticed is the beryllium tweeters have a narrower focus than the silk DI tweeters. Not a problem when seated at the proper listening level however, when standing the highs are noticeably diminished. I find the vertical dispersion to be not as wide as with the DI’s. As large as the Ulf’s are they do not seem to radiate as evenly throughout the room as the DIs or some other speakers (Thiel 2.2’s) that I have on owned. It may be that the sweet spot is just so amazing that other positions just can’t compare. One other observation is that I need to play these Ulf’s about 20% louder to equal the volume of my DIs. This is not an issue since I am powering the Ulf’s with a recently purchased pair of Parasound JC1+ mono-blocks which are rated at 850 watts in 4 ohms.  The Parasound JC1+’s  have replaced a pairs of PS Audio M700 Class D mono amps which did paired well with the Tekton DI’s.

I will try to describe the tonal character as best I can as an amateur evaluator. First, these speaker will project what is feed them from up stream, equipment and source matter, recording quality will impact what you hear. Room treatment has been a large part of my journey in this room and the position of the panels can have and enormous impact on sound stage and imaging in this room. 
Some of my seventy’s rock music whether CD, LP or streaming just never got to the audio nirvana I was hoping for. However, put a quality track on the system and you will be rewarded by these speakers. The Ulf’s are neutral in general as is the rest of my system. The bass is tight and deep, there is mid-bass you can feel. These speakers provide layered micro detail in the mid’s and have highs that are not bright or harsh but provide satisfying leading edge clarity.  As with all Tekton speakers the Ulf’s are as dynamic as any speaker I have heard, concert level dynamics, as loud as you dare to push them. 

A couple of tracks that I believe really allow the Ulf’s to show what they are capable of are:

Some of you may ask do you really need two subs? Absolutely, while you would think that the two 12” woofers (4 total) offer all the bass you could ever want, that is not the case in my opinion. The bass from the Ulf’s while satisfying will not give you that live experience many will crave. I’m not talk bloated, thick heavy bass, no this combination offers deep, quick, tight bass that can’t help but make you smile. Your neighbors might disagree if they are close by, but lucky for me that is not the case. 

In conclusion, I believe the Ulfberht are one of the best sonic values available. If you have the room and a supportive wife, I am bless to have both you owe it to yourself to hear these amazing speakers for yourself, my listening room is available if you are ever in the Midwest (Ohio). Thanks for your interest in this review, enjoy the music and enjoy the journey.

Equipment and Room

About the Room: 24’ x 30’ with 12’ ceilings. The painted wall behind the system is the custom painted portrait wall we used in our business and was preserved to remind us of our roots (we owned portrait studio for 40 plus years)  During COVID we remolded the room gutting and removing the lighting system and added a 24” bulkhead round the ceiling, which includes 24 foot of 8” thick sound absorption batting built into the corners and the sides of the bulkhead. The room also serves as a home theater space with and retractable 150” screen and a separate AV equipment rack in a side closet. The two channel system has 3 - 20 amp dedicated circuits, with one additional dedicated circuit for the Marantz AV receiver.

Special note: Free tweak. I recently watched a YouTube video by Acoustic Fields and they spoke of stacking some of their foam absorption material between the speakers. So on a whim I moved two of my portable absorption panels that normal sit on the first reflection points to the outside left and right of the main speakers. I placed these 2 - 60” x 24” x 4” panels in the center between the speakers in front on my equipment rack (as pictured). The result “ mind blowing” I would have never guessed the difference in clarity and presence this would make. Better imaging and a more solid center image. Try it if you have the chance, you won’t be disappointed. I know this is not as attractive of a setup, it has and even less WIFE APPROVAL FACTOR but, easily moved when necessary

I have photos, however, I'm not sure how to add them to this post.
