Roger Sanders doesn’t attend many audio shows these days. For an industry pioneer and company CEO, he’s remarkably low-key. But if you catch him in the right mood outside the door of his exhibit room and ask good questions, look out. He’ll talk your ears off.
That was the very pleasant — and fascinating — experience I enjoyed at the 2016 Rocky Mountain Audio Fest. I had just completed a lengthy demo of the Sanders Sound Systems Model 10e electrostatic hybrids with a company rep when I stepped out the door and ran into the founder holding court with another audiophile.
The sound of the Model 10e was still reverberating in my ears. The demo had included a wide variety of musical genres, including jazz, pop and rock, along with the usual drum-and-percussion-heavy, audio-show tracks.
Willie Nelson’s “Stardust,” in particular, was stunning, with the spliff-loving legend’s weathered voice sounding more textured and authentic than I’ve ever heard it. Stevie Ray Vaughan’s “Tin Pan Alley,” meanwhile, proved this hybrid electrostat had no stereotypical politeness. Double Trouble was in the house, and you needn’t bother knockin.’
As part of the demo, the Sanders rep turned the panels off, using the proprietary digital line stage/electronic crossover. Immediately, vocalists and everything from the midrange up dropped out. I don’t mean those frequencies were somewhat attenuated or faded to a whisper — I mean they completely disappeared, leaving only the pulsing bass and steady kick drum.
With the test, it was easy to see why Sanders’ design enjoys such clarity. Combined with the strong, fast output from the aluminum woofer and the hybrid’s uncommon dynamic punch and high-power handing capability, Sanders seems to have found a way to make electrostats do things few — if any — others can.
“Electrostatic panels are like a stretched drum head. They ring at lower frequencies. So, I set my crossover at 170 Hz to avoid a resonance at 86 Hz. Then I use a sharp 48 decibel-per-octave filter to roll off the bass fast, before it gets into the midrange,” he told me.
If Sanders stopped there, he’d probably have a pretty fine speaker. But, with the Model 10e, he’s gone beyond — far, far beyond. His website is filled with the kind of long, detailed white papers you might find in an engineering journal. Sanders has thought this stuff out, and he’s not afraid to stand against convention.

One of his iconoclast views concerns the sweet spot. Sanders sets up his demo rooms with a single line of chairs dead center on a line from the midpoint of the plane the speakers are in. That leads some to knock his choice of flat panels for his towers. But Sanders contends that curved panels (a concept he engineered himself, then abandoned) produce smearing and resonances. A flat panel is more accurate, he believes.
His obsession with this issue and high-end sound in general has led him to study every imaginable factor that goes into producing state-of-the-art fidelity. And when you listen to him expound on his theories, they all seem to make perfect sense. Partly, this could be due to his enthusiasm, which hasn’t waned since he started his audio experiments decades ago.
Other keys to the 10e sound include careful time alignment and extremely low distortion. In addition, Sanders would like to control the electronics side as well.
Each Model 10e ($17,000 a pair) comes with its own house-made Magtech stereo amplifier and the aforementioned preamp/processor, which also offers digital room correction and DSD equalization. Those functions are said to be user-friendly.
Another amp also is needed, since the system must be bi-amplified. The buyer can used an existing amp or buy another Magtech for $5,500. In the case of the latter, that would push the overall cost up to $22,500.
Looked at as a whole system, and considering the reference-level reproduction and handsome woodwork, you could make a strong case that the 10e is one of high-end audio’s true bargains.
“I’ve been told by many people in the industry that I should charge more,” he said. “Some potential customers have been put off because they thought they should be spending more — that doing so would somehow get them better sound. But I just want to offer the best product I can at the most affordable price possible.”
Listening to Sanders, I got the impression he really is being earnest about this. If you peeked into his garage, I doubt you’d see a Lamborghini in there.
Meanwhile, he spends his time selling his speakers and electronics direct from his Colorado office/factory (there’s a 30-day risk-free trial) and not particularly courting publicity for himself or his company. But why do that, anyway, when your products speak for themselves?
Sanders Sound Systems

I admit it: I’m an absolute sucker for electrostatic speakers. There’s just nothing like the presentation of a good electrostatic speaker in terms of speed, delicacy, transparency, and very low distortion. And the Sanders Sound System setup featuring their Model 10e ($17K, including the Sanders Magtech amplifier) sounded much better than merely “good;” in fact, it sounded excellent to my ears. The 10e features a 15”x42” electronic panel over a 10” aluminum transmission line-loaded woofer, adding up to an elegant 69” package that should suit a variety of rooms. Although the selections played while I was in the room were unfamiliar, there was no mistaking that ol’ electrostatic black magic: crystal clear and three dimensional as all get out.
In terms of beaming, well . . . there’s not much you can do about it engineering-wise, so you’re going to have to accept a small sweet spot. But Sanders, to their credit, didn’t try to obscure this characteristic and set up the room to really optimize the listening position of the system: three chairs that formed what’s commonly referred to as the “audiophile choo-choo.” It may have ultimately limited the total number of listeners who passed through, but those who sat in one of the three chairs were sure treated to some excellent sound. Bravo!
