Piano at end of hall

for the love of music

Violin of musical notes

Do you look forward all day to being dazzled by an aria or piano concerto? Irresistibly bobbing your head to fine jazz riffs? Jumping around to music that rocks? Exploring new titles on your high rez streaming service?

Whatever fires your rocket, you might worry that a pair of loudspeakers that make any genre come to life with impeccable nuance, force, and clarity would be boring. You know, no tweaking or imagination required to hear the real thing. But the real thing is absolutely not boring, because no matter what you play on JansZen loudspeakers, you feel plugged in. You feel connected.

It's the absolute immediacy of electrostatic sound delivery that does it. Unlike conventional loudspeakers, where music is delivered through heavy, complex drivers, it just just flows though a JansZen's electrostatic simplicity like an open window, exactly as it was recorded. Immediate. Effortless. Intoxicating.

Thanks to an elegant operating principle and superior physics, electrostatics are the only devices capable of recreating the true essence of live music.

You've probably noticed that electrostatics aren't common, and that's because they're hard to implement, despite being simple in principle. In addition, they've got to meet modern standards of performance and reliability, while also well suiting home environments. It's a tall order, but JansZen, being the company that invented and brought to market the first practical electrostatics in the 1950's, has a leg up on all that.

We all we know musical instruments make sound by vibrating the air in a wonderfully wide range of ways. But loudspeakers are stuck imitating musical instruments by vibrating diaphragms, and a convincing imitation is only possible when the diaphragm is so light that it essentially disappears.

The only loudspeakers with vanishingly light diaphragms are electrostatics, and the only way to vibrate such a light diaphragm is with electrostatic force.

In an electrostatic, a polymer diaphragm thinner than 1/10th of a human hair vibrates uniformly and linearly, solving the basic coherence and distortion issues.

On top of that, electrostatic diaphragms are the only ones lighter than the air they vibrate against. Wispy, virtual air barriers make sound, rather than complex, vibrating mechanisms.

You can read more here about what makes lightness matter, and here about how conventional loudspeakers distort the sound. The TECHNOLOGY menu above also has further information.

JansZen loudspeaker review excerpts

In JansZens, electrostatics cover the midrange and treble, which is where the magic is. To that essential magic, we add the satisfaction of deep, clean, impactful bass with seamlessly integrated, fast, low distortion woofers.

At this point, you're probably wondering, if electrostatics are so great and cones are so bad, why do we use cones for the bass? Well, first of all, making deep bass and palpable impacts is not a delicate operation. At least in our case, woofers must execute a tricky combination of grunt work and nuance, and getting it right depends on which woofers and how they're used.

The first thing that's required is for the woofers to act as solid pistons, with no chance of deviating from uniform motion. Nowadays, the best woofers can do that, as long as they're not asked to make sound above the bass frequencies, where they'd break up, nor pushed beyond their linear excursion limits. where noticeable distortion would set in. Since our crossovers are at a very low 500 Hz (just above middle A), our woofers are as free of breakup coloration and distortion as our high purity electrostatics.

To attain our famously undetectable hand-off between the two types of driver, we do employ a few tricks, as well as use the best woofers for this sensitive job. We also have ways of getting get deep bass from our compact, sealed enclosures, that is, without employing transient-wrecking ports.

Between the low distortion, the lack of coloration, the seamless integration, and our careful attention to crossover design, the woofers give no clue that the entire loudspeaker isn't electrostatic.

JansZen Valentina revealing drivers

Good looking, easy to place, and musically transportive

Last but not least, the attractive cabinets suit a wide range of decor, so arbiters of household furnishings tend to welcome them into the home. They're also easy to place, partly because they don't emit the space-demanding back wave that dipolar electrostatics do.

Controlled dispersion minimizes the amount of sound that would otherwise be bouncing around the room, and this reveals an enveloping sense of the original spaces where the recordings were made. This sense of space provides a convincing you-are-there experience, transporting you to the original performance.

The minimal room interaction also reduces the need to prioritize living space considerations over acoustics. Room treatments and furniture arrangement are thus relatively unimportant, although of course they do matter for optimum performance, as with any speakers.

If you're a woman, you may be glad to know that a critical range of frequencies, where conventional speakers tend to sound harsh, is instead as smooth as silk. This is because that range (1 kHz – 3kHz) is on the electrostatics, which are incapable of making peaky sound.

With JansZen hybrid electrostatic loudspeakers, you get the best of big electrostatic performance, without the usual drawbacks, plus the deep bass and concussive dynamics of a traditional loudspeaker, all in a deceptively compact, space-saving design. Audiophiles will especially appreciate the deep, wide soundstage and the realistically sized instruments floating above the speakers.

The advent of JansZen hybrid electrostatics means there's basically no reason left on Earth for anyone to live with the drawbacks of conventional loudspeakers or accommodate the space requirements of full range electrostatics.

As many satisfied music lovers have discovered, a pair of JansZens can fulfill your quest for musical authenticity and consistent enjoyment, and still satisfy the general preferences of the rest of your household.

Electrostatic nuance and clarity plus bass and punch

Controlled dispersion; no back wave -- like being there

Passive and active versions

Pair of JansZen Carmelita stand mount electrostatic hybrid loudspeakers on stands

Stand-mounts, too

Our stand mount loudspeaker is called the Carmelita, starting at $4850/pair.

Both the Valentina floor-stander and the Carmelita stand-mount are available in passive or active versions. Both models are compact at only about 40" [1m] tall. Both have the sonic hallmarks of much larger speakers.

The actives feature a high grade, on-board DAC and five independent inputs -- two analog and three digital. The analog inputs are sensitive enough not to need a preamp. The inputs automatically self-activate, based on which one has a signal, A remote control comes standard for volume and other functions.

Imagine eliminating your amplifier, preamplifier, DAC, and speaker cables, all at once, and getting not only more convenience, but also exquisitely clear and natural electrostatic sound.

There's a new special option available on the Valentina, called Sound Everywhere (SE). You get real-time, remote control selection between directive vs. omidirectional sound dispersion. In the sweet spot, the difference is between a you-are-there vs. a they-are-here experience. In omnidirectional mode, the sound is uniform throughout the room, so you still get great sound when you're not in a listening seat.
