Tekton Impact Monitors


Hi All,
I'm relatively new to Audiogon but have trolled the discussions for a few months. I have been listening to Spendor LS3/5As driven by a Quad 34/306 combination since the late 1980's and decided that it was finally time to upgrade my speakers. I love the Spendors but they are very limited in dynamics and scale. I auditioned the SVS Ultra Bookshelf speakers and while they brought some additional scale they simply didn't have the sweet midrange that I can't live without. I listened to some open baffle speakers (Emerald Physics) and loved them, but their size and need for space worried me, and I found them less satisfying at moderate and low volumes, where I do a fair bit of listening. I was fascinated by all the discussion regarding Tekton speakers and was considering getting a pair of Enzo 2.7s, but after a short discussion with Eric I followed his recommendation of the Impact Monitor with upgrade. They have the 7 tweeter array and a pair of 6.5" woofers and are rear-ported. I use a pair of SVS subs (the sealed variety). The Impact Monitors are simply amazing. The midrange is oh-so-sweet (very similar to my Spendors, but with more air) and the detail, even at low and moderate listening levels, is superb. The imaging is even better than my Spendors managed and the scale is huge and is much more music-appropriate. My system is really quite modest but now when I walk into my listening room (doubles as our living room - thankfully my wife appreciates Hi-Fi) I get the audio-show feeling of "being there". I have a Denon DP59L turntable with a DL110 HO moving coil cartridge running through an Emotiva XPS-1 phono preamp and the Tektons are absolutely incredible with classic rock on vinyl. I'm not sure how Eric managed it, but these speakers are superb, even with my 30 year old Quad electronics. I believe they are basically the top 24" of the Double Impacts, but are rear-ported rather than front ported. I can heartily recommend them and Eric and his team are great to work with. I'm not sure how many other Impact Monitors are out there since the pair I have are S/N 0005 and 0006!

REVIEW – TEKTON DESIGN IMPACT MONITOR

PRELIMINARIES

I’ve been reading a lot about Tekton Design’s Double Impact speakers. When a professional reviewer, Terry London, chimed-in a few months ago with his super positive review I started paying even more attention to what people were saying. I stalked the boards and asked a few questions mostly about listening distances and room sizes. I finally emailed Eric. He responded right away and when I called, Karma put Eric on the phone for a short conversation to confirm a few details. I decided on the upgraded Impact Monitors and since he had a pair in-stock Eric promised to ship the same day. I received the tracking number shortly after the call and had the speakers about 4 days later. They arrived well packed and without a scratch. The fit-and-finish of the standard cabinet is excellent. No complaints with communication, shipping speed or quality from me.

I spent considerable time figuring-out where to place the Impact Monitors in my room and what listening distance to use. My listening room is 25’ x 15’ x 10’. I ended-up with them 42” from the front wall and about 5' from the closest sidewall. My listening position is 8’ from the front baffles with the center tweeters at 43"which is ear height. They sit about 9' a part.

I ran them continuously for 5 days. The sound opened-up a little each day but I had a hell of a time getting the lower midrange and bass to sound right. No matter where I placed the speakers, or my REL subwoofer, the low-end sounded weird. It sounded thick/smeared and no way in the same league as the upper midrange and treble. I tried different speaker stands and spikes. I tried different cables. I added a Synergistic Research carbon XOT, which helped, but the sound in the low-end was simply screwed-up. I knew it wasn’t my sub because the problems occurred even with it turned-off. Finally, I remembered “the cheapest but most effective tweak”: tighten the mounting screws around the speaker cones! (Don’t over tighten them just make sure they are snug) Well, low and behold a screw on one of the 6.5” speaker cones was very loose and a couple of tweeter screws needed a few turns to completely secure them. With all the screws firmly in place the bottom octaves snapped in to focus - tight yet with plenty of texture and bloom.

I have a number of tube and solid-state amps that I tried with the Impact Monitors. I really enjoyed a 25 watt Class A amp with them but I ended-up preferring my 200 watt tube mono blocks. I readily admit the choice of amps is subjective so your mileage will obviously vary. Rest assured any quality amp will work well with the Impact Monitors. Even my flea-watt SET worked well. However, remember, in normal configuration, they are 4 ohms (8 ohms is optional) and are rated at 94db sensitivity.

My taste in music is mostly jazz, blue grass, country and rock. For instance, I listen to a lot of Gov’t Mule, Gregg Allman, Neil Young, Holly Cole, Shelby Lynne, Johnny Cash, Nickel Creek, Earl Scruggs, Led Zeppelin, Clark Terry, Oscar Peterson, Duke Ellington, Ella Fitzgerald, etc. If I listen to classical music, it’s usually solo piano, cello or violin.


LISTENING

Even during the set-up period I could tell these speakers are special. If I were to describe their sound in one word it would be: “natural”. The tone is spot-on and they present a very coherent dynamic sound – much like good horn speakers. They don’t sound laid-back, forward or any other term – they just sound right. There are no overdone highs or lows. When a vocalist sings an “s” it doesn’t sound like a “z”. Bass guitars don’t sound like one note blobs. Violins don’t sound like nails on a chalkboard. As he claims in his ads, Eric has “captured the harmonic spectra of the music being played”.

They image as well as anything I’ve had in my listening room. Each performer is properly placed in the soundstage but they aren’t etched in stone – just like live music. Depth, width and height of the soundstage are excellent.

The Impact Monitors “only” play down to 40Hz or so. Based on your listening preferences, or room requirements, that may be low enough. I would avoid pushing them into corners or towards the front wall to augment their bass. Instead, as mentioned above, a subwoofer when properly set-up is a very viable solution if you want more bass. I realize you could buy a pair of Double Impacts or move even higher up the Tekton food-chain but space constraints, cost or even aesthetics in your room my prevent that.

Finally, I need to mention my extensive use of Synergistic Research (SR) equipment. The SR stuff has always had a significant impact on the sound in my system and that was especially true with the Tekton speakers. I listened for a while with the SR Atmosphere/FEQ turned off and the soundstage suffered. Not that the soundstage was bad but it REALLY shines with the SR technology engaged. I highly recommend you try SR with Tekton’s new tweeter array.


SUMMARY

Tekton Design’s Impact Monitors do very little, if anything wrong and enter the realm of unbelievable value when you consider their price of $1,800 ($2,100 with upgraded parts) delivered!

sbayne,

Thank's for your very through summary of this Tekton monitor speakers.Sounds to me like you are really enjoying them and took your time to really optimize them into your system.

For those folks that are interested in this speaker I do believe the true sensitivity is 91db with 1 watt @ 1M.The rating of 94db is with a input of 2.83 volts.

Can you tell us which tweeters that your pair came with.

Kenny.
Thanks Kenny.  Thats right, Eric shows the specs on his website as:

  • 94dB 2.83V@1m sensitivity
  • 4 Ohm design for optimum performance (8 Ohm available please inquire)
  • 40Hz-30kHz frequency response
So the conversion would be 91db sensitivity with 1w@1m. The tweeters appear to be SB Acoustics SB26STCN-C000-4. Have you heard the tweeter array with the ring radiators? Is there any difference in sound that you can detect?  
sbayne,

I have the sb acoustics SB29RDNC-C0000-4 ring dome tweeters in my DI's and I haven't compared the 2 tweeters but I seriously doubt any big differences.

Even though neither tweeter is made from exotic materials,they are most definitely always in the sweet spot of very low excursion in this speaker design and I would also say that they sound "Natural" and never fatiguing to my ears like some designs can,and on the detail side of things I do not feel like I'm missing anything and only have gained a more Engaging sound overall.

You mentioned the band "Gov't Mule,I haven't listened to any of their music in awhile and I hope Tidal has them because I misplaced or lost my Cd's when we moved 3 yrs ago.I like them and think they are quite a unique sound.

Kenny.
Yeah, Govt Mule is a classic band founded by Warren Hanes and Allen Woody of the Allman Brothers. Lots of stories with this band.  Great musicians. (Tidal has them. Check out the Dose album!)
