I think the hybrid is the addition of mid bass drivers to the Moab design, this may take it closer to the Ulberth. Definitely like to see some photos
How many Tekton owners went for the bi-wire or bi-amp option? My current speakers sound way better bi-wiring them, but Iâve had other speakers that sounded worse when bi-wired. Was wondering how much the Tekton speakers benefit from being bi-wired, if at all?
And people (not on PS Audio forums) laugh at my Sealed Box 901âs which are âtechnicallyâ point-source albeit with EQ.
Wow. You still run 901s? The lust-worthy speaker of my youth. And Iâll bet they sound fantastic.

Oh itâs been a labor of love and hate. The rabbit hole started in Aug. 2018 when I scored a pair of 1968 Sealed Box 901âs with their original Tulip Stands but no EQ in Tucson, AZ. These things stunk of Cigarette Smoke and had water damage that didnât penetrate into the Cabinet fortunately. I got rid of the grilles and sanded down beyond the water damaged areaâs thereby ruining the original veneer - had no choice. Being a fan of NHT in the 1990âs, I had Arizona Plastics make 1/8â Black Acrylic Panels and a local metal finishingâs place also in Tempe, AZ powder coat the Tulip Stands. I had a Marantz receiver with Audyssey at the time and tried to dial in an EQ that would bring some life to the highâs. I wasnât convinced at the time about going the MiniDSP or original Analog Bose EQ Box route and rebuilding the components within themâŚYETâŚthe story gets better and worse.
Like you, umiami91, I too lusted after a pair since I was a kid. With the Audyssey EQ the highs were lackluster and there was no Bass. I then proceeded to buy a pair of McIntosh MC50âs off of eBay and they made the mids and highâs come alive but their still was no Bass. I have a Subwoofer in my old setup which I had to re-incorporate into my setup because their was nothing below 100Hz ! I rebuilt the MC50âs which widened the soundstage while maintaining the focus of the L & R front speakers. I also rebuilt (overbuilt) an eBay Series 2 EQ at this time. The EQ is is the secret sauce but power (WPC) was my enemy. Those Macâs are good for driving a pair of Horn Speakers or efficient domed tweeterâd towers or Stand Mount Speakers. They were no good at Bass extension for the big bad 901âs and their power robbing EQ curves.
For what I paid for the MACâs plus the money Iâd sunk in parts to rebuild them (unnecessary, but I had the âbugâ after rebuilding the Bose EQ by this time). I could and should have bought a Stellar S300 - stupid me - live and learn.
Onwards to 2019 and my purchase of a PS Audio Stellar Stack. A huge leap in sound quality compared t the Marantz AVR but Iâd been struggling with a bit of GND loop hum and Iâd Star GNDâd the box as per Paul McGownan & Dan DâAgostino (yes I just threw names at this story - unfriend me laterâŚLOL). Didnât help so I lived with it. You only heard the hum during low level passages anyways (I knowâŚnot funnyâŚfix itâŚnever did).
Fast forward to November of 2019 and I bit the bullet and bought a MiniDSP with true Balanced Outputs. All my connection are XLR and the GND loop was still thereâŚUNTIL the MiniDSP came into my life. I dialed in a Bose Series 2 EQ output from Rain City Audio that was measured at the âFlatâ Setting of a box heâd repaired. BingoâŚbetter than the stock boxes and absolutely no hum. But now I have low level hiss that can can only be heard when you are near the Speakers. At my listening position, it barely noticeable. Will need to make improvements inside my Homebrew Power Supply (Big Torroidal with Full Wave Industrial Rectifier and a very efficient adjustable voltage regulator).
With my recent PS Audio trade-in of my trusty SGCD for a DirectStream Sr. DAC, I am almost within a hair of Audiophile Bliss. The next step is getting the I2S output of the MiniDSP talking to the DS Srâs I2S input therefore bypassing the MiniDSPâs cheapo 48kHz/24Bit DACâs.
Even though (for now) I am running the Analog XLR Out of the DS Sr. Into the MiniDSP dialed with the perfect (to my ears) curve. I am sadly applying a Cheese Grater to the wonderful DAC that Ted Smith and the Team at PS Audio have designed. It still sounds better than the SGCD. WTFâŚLOL.
Sometimes hear Birdâs chirping through my Speakers. When I power Cycle the MiniDSPâs Power Supply, the problems gone. One headache at a time. Thatâs what this hobby is all about.
Old Pic with the Analog EQ
At the Tucson, Arizona DIY Speakerbuilderâs Event - I got A LOT of praise and felt vindicated. The Bottle of Glenfiddich also made the room VERY popular for those who werenât driving that day 
Tucson Front L, C, & R - note that I am not using the corners of the rooms in both my Apartment Setup and in the Space I created at the Show. It removes a lot of the Stereo Everywhere effect while creating a dead center Phantom (in Stereo mode) image while maintaining the L & R imaging.

Not many ordered them biwire I think. Go for single wire and 4ohms. Eric has discussed this on his videos and saves you the trouble and cost of additional cables for no benefit with his speakers.

I have a pair of Double Impact SEâs and theyâre superb. Alot of people over spent on their speakers and it makes them feel better to bash Tekton. So the Double Impact SE could easily be called a $10k speaker ($6k factory direct and add markup).
So itâs not like theyâre cheap.
Eric does a good job explaining why there are no phasing issues and even if there is, no one has heard it yet.

Those are a hot rodded piece of history. Kind of like a '60âs 'Vette with a new supercharged LS under the hood. Iâll bet you know more about 901âs than most on the planet. They are cool.
The Tektonâs are the new 'Vette with the supercharged LS. New tech. and power. Nothing seems to polarize stereo hobbyists more than speakers.
What makes me smile is people who say it wonât or canât work without trying it in their house before judging.

I heard the Tekton Impacts alongside the Zu Audio Soul Supremeâs last Summer at our Clubâs Speakerfest here in Phoenix. Sean Casey also was there (very nice Guy). Two different approaches to Speaker design but the results were phenomenal. The Tektonâs filled the room with high quality audio while still sounding like a pair of $10k Focals but better IMHO. The Soul Supremeâs on the other hand were half the size and yet they too filled the room with lifelike sound without drawing attention to themselves. These are the sound signatures I strived for with my 901âs. Setting them up as âOmni Directionalâ away from side walls totally goes against their setup manuals but eliminates the one note Bass Boom that they are known for. With a Subwoofer set at a 60Hz LPF, they are clean down to 35Hz and roll off nicely above 15kHz (I can only hear up to 13kHz anyways). The MiniDSP eq doesnât have the sharp cliff dive of a filter above 15kHz like the original analog boxes, and I do hear an improvement (strange based on my earlier words) in the treble side of things. 9 midbass/midrange drivers should comb filter like crazy and sound like a wet fart. But those Bose Engineers were onto something 52 years ago. Itâs a shame that they only build Speakers now in Professional applications only.
Maybe theyâll hire me to consult on 901âs if they ever decide to bring them back. Unfortunately, when Dr. Bose passed away, so did the production of the 901 Series 6âs. I donât see a Vintage run like the L100âs, Klipschornâs, Harbethâs, etc. Shame.
Thanks for the compliments.
Agreed. The ZUâs are another really well thought of line of speakers. There is no way that I will ever be able to listen to more than a couple more sets in my home system in my lifetime but it is fun to think about and research.
I am in the process of gathering pieces for a âbigâ system in the basement but it will be some time before that comes to fruition.
Lately I have been looking at some âopen baffleâ array and line source speakers from GR Research. They are mostly sold as kits but I would probably pay them to finish, assemble, test, and ship complete as my cabinet making skills are zero. Both are explained in this video. He seems down to earth and very knowledgeable and a no BS kind of person. A lot like Eric in that respect.

The more I read through these posts the more it seems like some of the Tekton owners are trying to get people to agree with them about Tekton. If you love your Tekton speakers who cares if some people donât. If I buy a pair of $50K speakers and you feel your $10K speakers are better, Iâm not losing sleep over your purchase. People buy all kinds of gear for a ton of different reasons. There is no one product that works for everyone. Everyone can make a case of why Brand A is better than Brand B.
Just enjoy and listening to some music.
I donât think they are trying to get people to agree as much as to not to be haters

I hope thatâs not the room he reviewed them in. Can you hear the echo from just his voice when he talks?
The mike sounds like it is in an echo chamber for the music too
