    Soon to be year three for our OB Sigma’s. I look at other speakers and then remember I’d have to part with Sigmas and I rule the deal out. Bad recordings show glaringly but good ones make you realize there is no substitute for the Sigmas. Imaging, bass, mid range, are perfectly balanced. They are driven by Red Dragon monoblocks and an Onkyo P3000R preamp. My wife grew up in Japan and at first she thought the Sigmas were too small. She says they are perfect.

    I bought the Perfect SET with beryllium tweeter and full internal upgrades. After 3weeks the woofers loosened up, and WOW! Full range 30-30k hz I like it! Truly amazing full range speakers! I run them with 8w 300b monoblocks in a large 45m2 livingroom and could not be happyer!

    All good online comments on these speakers are true, and then some!!

    Excellent speakers. I had high expectations for the midrange given the tweeter array, and I must say it delivered. What surprised me was how nice the highs are. The bass is great too, but in my former living room it was a bit tricky to place the speakers because of the bass output (there was a concrete wall behind the speakers; this isn’t a knock on the Tektons). I was actually thinking of selling the speakers because I couldn’t get them to sound right. I’m so glad I didn’t, though! Once I got into a better listening room, the speakers changed dramatically — I guess the importance of room acoustics can’t be understated. And to be fair, no speakers sounded good in that living room.

    For equipment, I’ve tried Schiit Aegir monoblocks, an Adcom GFA-555 II, and a Parasound A23+. Overall, I liked the Parasound the most. The Schiit Aegirs sounded way too lean – not enough bass or midbass, and midrange felt a like it lost steam at high volumes. Interestingly enough, a single Aegir sounded much better than two Aegirs, which I suspect is due to the monoblocks not liking a 4 ohm load. If you’re one of the other Electron owners (like Jeff in the other review), I’d encourage you to experiment with one Aegir in stereo instead of two as monoblocks. Your mileage may vary, but for me it was quite a difference.

    As much as I like Schiit gear, I found the Parasound A23+ to be a better match – clearer mids and better bass while retaining some of the warmness of the Aegir. I do want to give the Schiit another listen in my new listening room, which may change my opinion of this combination. The Adcom was hooked up to see how much power these things can take, and they certainly can make the house shake.

    My father is a lifelong audiophile and when he heard these speakers, he said “these are the clearest speakers I’ve ever heard.” They’re fantastic, especially when you consider the low price you pay for the customer service, build quality, and customization options offered.

    I have been living with the 2-10 Pef set for a couple of months now. If your impatient… bottom line awesome. Story is, wife hit the roof when she found out I spent $2100 on speakers. I made the excuse that because of COVID19 we’re not going to vacation, eat out, movie etc why not enjoy being at home. She knew I was blowing smoke but it had a ring of truth to it. Mind you, my system is a Akai AM52 I bought at Costco 30+ years ago and a Dac I paid $90 on Amazon. Just to give an idea how good it sounds, my neighbor has a system $50,000+ McIntosh, Focal yad yad top shelf stuff. We were listening to it and I was grinning and shaking my head. He asks “what do you think?” I didn’t offer up an opinion, but simply ask him to come over and listen to mine. I turned on dire straits, money for nothing spiritual levels and he was slack jawed. The wife likes them too 😉

    I am a new owner of the OB Sigma. I have prior experience with open baffle speakers (through companies that specialize in them), and my early impression is that the Sigma OB offers exceptional performance at over half the price of those other brands. They seem to strike the perfect balance between the openness and clarity of an open baffle design and the dynamic punch of conventional box speakers. It pairs very well with my Doge 10 tube amplifier. It also has an unobtrusive, simple, and elegant design and the build quality is excellent. A hidden gem in the Tekton line up and a true bargain at this price point.

    Love my Electron SE’s! Fast, firm bass from the dual 8″ woofers that with the 5″ mid bass drivers, integrates beautifully with some of the most detailed and lifelike midrange reproduction I’ve heard from any speaker at this price point and beyond. Then there are the nice smooth, extended and detailed highs to put the icing on the cake. Then there are the dynamic punch and speed with a spacious wide and deep soundstage and excellent tonal color reproduction. I’ve had mine for about 6 months now and every time I sit down to listen I am mesmerized by the sound. In my room, which is 19’x13’x8′, they sound HUGE and absolutely lifelike. I simply could not be any happier with my choice. Wonderful speakers and a bargain at their price. I bought my first component system at the age of 14 in 1969, so I have owned more speakers and audio equipment over the years than I can remember. The Electron SE’s have been my most satisfying speaker purchase ever. I power them with both tubes(PrimaLuna EVO 100), as well as my AVA Vision SET 400 SS amp at times. I also pair them with Schiit Aegir power amps from time to time. All of these combinations sound wonderful. The Electron SE’s will give you what you feed them. I am a very happy owner!

    After having owned Vandersteen, Martin Logan and several other very nice sounding systems, I conceded to take a leap of faith with Eric’s products, finally electing the Moab with Be HF drivers. After more than a year of listening now, I’m convinced that, for me, I’ve found aural “shangri-la”. These and every other unit in Eric’s offering are the best value to be found. As for my Moab’s, I have auditioned competitor units costing ad much as 10-12 times their price and find them equal to if not superior to them in every way. A very smooth frequency response without any “hot spots” in any of the audio or video passages of the content I’ve listened to. I’m just as picky about balance and sound field integrity in both of those areas. I’d thought that I would need to add a sub for some of my video contents demands, however, my concerns were quickly put to rest as the Moab’s aptly handled them convincingly and with ease. Are there better sounding speakers out there? Yes, but at a cost that would rival buying a starter home in many places. Even with modest equipment they outperform a great number of contenders. That being said, music and sound are very personal. Everyone hears differently. But in the eyes of this beholder, he’s certainly found the hidden gem, a “pearl of great price” one might say. So, take the leap, you will not be disappointed. And, thank you Eric, for your vision, for your genious and for your love of music which I’m sure was a great part of what brought you to this point. Stay the course and… See the sound.

    Hi Eric,

    The Tekton MOABs are a majestic masterpiece both sonically and visually.

    They perfectly bracket my 85” Sony 85X950G 4K TV sitting on top of the Sonax B-003-RBT TV stand.

    The TV stand is 75” wide which exactly matches the width of the TV. The stand is 22” high while the height of the TV adds another 46” making the top of the TV 68” from the floor.

    The MOABs stand 71” tall on spikes. These slender columns act as perfect bookends for the giant TV.

    The proportions are just right. Aesthetically, the speakers, TV and Stand act like a monolithic facade 102” wide by 71” tall.

    They blend so well that it looks like a custom design.

    I am including two pictures of my entertainment system, one showing the MOABs with the grilles and one without.

    Now let’s talk about performance.

    Sonically, the MOABs are a knockout. The price/performance on these speakers flirt with the impossible. There are no other speakers on earth that can touch the performance of the MOABs at this price point. They put speakers costing 5 to 10 times more to shame.

    It was a magical experience the first time I heard the MOABs at RMAF 2019. It was the micro-dynamics of the mid-range that made them sound so special. Voices were rendered with incredible delicacy and detail. This was all the result of your patented speaker array.

    I was surprised to find that they sounded better than the Wilson Sashas with Watch Dog subwoofers playing in the opposite room. How is it possible for a pair of $4,500 speakers to outperform a Wilson Audio system costing $58K?

    Everyone who auditioned the two systems at the show came to the same conclusion.
    I listened to every other setup at RMAF and came to the conclusion that the MOABs are the best bargains in hi-end audio. This is as close to a perfect speaker one can find at this price point.

    I consider your patented design and passion for building high-performance speakers a gift to the audiophile community.

    Now I am one of the happy owners of a set of MOABs. They have exceeded all my expectations.

    The MOABs can be imposing while standing freely in the room. However, that can be easily remedied by placing them next to a giant TV as I have done. If the heights match, it makes them look like an extension of the TV.

    The MOABs do a good disappearing act since they image so well. You feel like being immersed in a wall of sound. If you dim the lights while watching a movie, you become oblivious of the MOABs. I am including a third picture showing how elegant the system looks with the lights turned off.

    Finally, let’s get into some technical details.

    I looked at the tweeters by shining a flashlight through the rear ports. I could see that the MOABs are using Wavecor TW030WA06 4ohm tweeters.

    These are high quality drivers used in expensive speakers. Each costs $87.

    https://www.parts-express.com/wavecor-tw030wa06-30mm-textile-dome-tweeter-with-rear-chamber-with-ferrofluid-4-ohm–298-1110

    There are 30 Wavecor drivers in the MOAB pair!

    The retail price on these tweeter alone is $87 x 30 = $2,610.

    Looks like the 12” woofers are from the Eminence Pro Audio line.

    https://www.eminence.com/pro-audio/professional-series/?size=12#speakers

    I am guessing the MOABs are using the Eminence model DELTA PRO 12-450A.

    https://www.parts-express.com/eminence-delta-pro-12-450a-12-professional-midbass-woofer-8-ohm–290-511

    They retail for $120 each. The MOAB pair is using 4 woofers.

    This brings the price of the 34 drivers in the system to $120 x 4 + $2,610 = $3,090.

    To get the complete bill of materials, one would need to add the cost of the crossovers, internal wiring, cabinet, binding post and finish. Then you would have to account for labor and cost of shipping.

    This simple math should suffice to make one realize why the value of the MOABs flirts with the impossible.

    Typically when one buys a $4,500 high-end speaker from a manufacturer supported by a network of distributers and dealers, the cost of the drivers seldom exceeds $900 or 20%.

    With the MOABs, the end user is getting $3,090 worth of drivers on a system that costs $4,500 delivered.

    It should come as no surprise why the MOABs sound so good using these expensive set of drivers. It is mathematically impossible for any other competitor to match this incredible value. Being an Internet Direct company, you have no overhead. You can pass the savings onto the end user.

    It is obvious that this is your passion. You sincerely desire to give your customers the best possible value.

    I hope more audiophiles get to know about your product through word of mouth. You have acquired a patent that can revolutionize speaker design.

    You are an extraordinary speaker designer and I wish you great success.

    Looking forward to experience what new surprises you may bring to RMAF 2020.

    Best regards,

    David Das

    What are these? They are the size of Encores at 62 inches. They have the drivers of Moabs, with upgraded Beryllium tweeters. They have the driver configuration like no other Tekton speakers. These Tektons were created because a customer (me) wanted speakers with the performance and price of the Moabs, and the size of Encores. Instead of sending me away, Eric Alexander built me custom Moabs. As you can see, they are in my choice of color, and they are beautiful. I once owned the Lore S, Enzo, Electron, Electron SE, and now my custom Moabs. I loved the sound of all of them, and they are now being enjoyed by others.

    I “broke in” my custom Moabs for the last 3 weeks, and the sound is amazing. They have much deeper bass than my Electron SE, and the transparency of Magnepans. I heard the Double Impacts, and my Moabs blow them away. The biggest difference, is they sound more live and the dynamics are at a different level than anything I ever heard. Live like sound is what everyone desires. The attack of instruments and vocals are absolutely stunning. It is what is missing in most speakers, which prevents the live like experience. I assume the standard Moabs sound the same as my custom version. I am honored that a world class speaker designer, built me custom speakers to fit my needs.

    I have waited two weeks after receiving my Impact Monitor speakers to write to you and express my feelings about your speaker. Before ordering, I did my homework and studied numerous reviews. Always with a cautious mind, thinking that the hype may be greater than the reality.

    ​Well, after two weeks, the smile on my face that immediately surfaces each time I listen to MUSIC as it plays on your speakers does not fade. Each day I become more enthusiastic, assured about my decision and believing that I have found a musical median that I will hold on for many years.

    I am truly impressed and satisfied. I can’t explain better other than to say, that when I listen to music and close my eyes, I can easily transcend to the source and even walk around the stage while the musicians play. Simply put, I am very happy with my choice. I never thought that I could ever experience this type of satisfaction. Thank you for the work you have done and the resulting product. Unfortunately, for me, another thought is, “what would the experience be like if I listened to one of your upgrade speakers?” For now, I will set this thought aside, appreciate what is in front of me and continue enjoying the music.

    My best regards,

    Camilo
