Sidebar 1: Specifications

Description: 2.5-way, floorstanding loudspeaker with sealed enclosure. Drive units: two 7" (180mm) W × 8" (200mm) H electrostatic panels mounted one above the other; two 8" (225mm) alloy-cone woofers; 1" (25.4mm), silk-dome auxiliary "airLayer" tweeter. Crossover frequencies: 500Hz, woofers–electrostatic panels; 5kHz, 1.5-way electrostatic panels. Crossover slopes: first order, 6dB/octave; the airLayer tweeter rolls off with a critically damped, second-order slope below 2kHz, with no upper rolloff. Frequency response: 30Hz–20kHz ±3dB in-room. Nominal impedance: 6 ohms. Minimum impedance: 4 ohms. Sensitivity: 87dB/W/m. Recommended amplifier power: 40–400W into 8 ohms; 120W nominal for max steady state SPL; 240W for full headroom for transients. Peak SPL: 108dB (pair playing music at 13' (4m) in midsized room). Electrostatic power supply: 0.1–1.0W, depending on mains voltage; works from any mains worldwide without adjustment; built-in surge protection. Tone controls: ±3dB, woofers; 0dB to –6dB, electrostatic panels; 0dB to off, auxiliary tweeter. Supplied accessories: high-durometer (hard) rubber feet or carpet-piercing spikes.

I've been waiting for Stereophile to review the Janszen speakers! They have always intrigued me, not only from the excellent reviews and user reports, but due to their approach to using electrostatic panels in a sealed box design.

To that end, the only thing that disappointed me in the review is that I didn't see addressed what to me were the intriguing questions about such a design:

What does the Janszen design sound like relative to other electrostatics or box speakers?

Does it still have an electrostatic speaker character? Or more of a box speaker character? Or something in between?

Electrostatic speakers have a reputation for sounding particularly "quick" and vivid especially with transients, along with that famous open-window "boxless" sound.

For me (and I know many others) there is also a sort of signature to most regular electrostatic speakers where, as vivid and boxless as they sound, there is a lack of palpability, of air-moving density, that you get with a typical box speaker. It's a bit more ghostly-sounding vs flesh and blood. You hear more than feel the sound.

I've always wondered how much this has to do with the use of electrostatic panels per se, vs the fact they just have no box, and also operate as dipoles which can energize a room differently.

So I wonder if the Janszen approach of putting the panel "in a box" edges the sound more towards a box speaker (including that added density and presence), so you get a sort of melding of box speaker/electrostatic sound, or if it still sounds like an electrostatic dipole speaker, with all the usual characteristics one hears in electrostatics.

Any comment on these comparisons, Mr. Atkinson?

Cheers!

Good description. I haven't heard any electrostatics other than Martin Logan's, but that summed up pretty well my reaction to them. I guess I'm not used to that type of sound, but it seemed kind of "hollow" to me.

The "open" quality you describe is, in my experience, unique to electrostatics. As is the "ghosted" quality of small electrostatics (good description). The latter problem disappears when the electrostatic panels are quite large, especially compared to the size of the listening room. I have owned Quads, Beveridges, and KLH 9s (double pair), and only the 9s, when used in single pairs in a small room or doubled up in a larger room have overcome the "ghost" problem. The result can be a shocking degree of realism, at the expense of listening room real estate. Back in the '80s, the engineers at Ampex Corp. designed a giant pair of electrostats built into a wall at one end of a listening room. The realism of the sound totally overcame the poor acoustics of the bare room facing them.

Hi

Really? What a HUGE claim !

KMD claims their products "faithful to make ZERO energy loss" from electrical signal to audio signals.

Technically, how can any dynamic drivers like those made by KMD achieve "zero energy loss" in converting electrical energy to sound energy ??
This is physics, my friend.

KMD also claims their products were "The World's First Spealers that sounds like LIVE MUSIC. That's a huge claim !

I wonder how KMD defines its "Live Music" ?????

Listening with own ears is believing

They were using very cheap gear, cables and CD Player too !!
