Duke LeJeuneAudioKinesis logoDuke LeJeune's background is primarily that of a hard-core hobbyist. He designed and built his first pair of speakers (a three-way transmission line design) in 1979. Over the next couple of decades he built over sixty different designs, and along the way published a couple of articles in Speaker Builder magazine.

In the late 1990's Duke discovered Sound Lab electrostatic speakers designed and built by Roger West. He was so impressed by them he bought the first pair of Millennium-1's ever made, and subsequently became a dealer for them. Looking for best equipment to match up with the speakers, he also became a dealer for several other companies for amplification, cables, and other gear. The business AudioKinesis was born, and other high-quality lines were added along the way.

The year 2005 found AudioKinesis in a major move from New Orleans to Preston, Idaho, and shortly thereafter the first AudioKinesis loudspeaker designs were launched. These drew on lessons learned directly from Roger West, Earl Geddes, and Wayne Parham, as well as studies of the writings of Floyd Toole and others.

AudioKinesis Zephrin 46 systemThe Zephrin 46 is uniquely designed to work with the room, rather than against it; and to work with the ear/brain system, rather than against it.

The idea behind its unusual configuration is this: We want to recreate as life-like a reverberant field as possible because that's a critical part of live music that few speakers get right. In order for the reverberant field to feel right, it must be spectrally correct, fairly well-energized, and relatively late-arriving (at least 10 milliseconds ballpark time delay before strong reverberant energy arrives is desirable).

AudioKinesis designer Duke LeJeune has been building award-winning controlled-pattern bipole speakers for years, but they had the same distance-from-the-wall requirements as dipoles. Inventor James Romeyn took a fresh look at this requirement and developed the Late Ceiling Splash configuration, which fires the rear driver array from the floor up at the ceiling.

So we have a very clean, controlled-pattern first arrival sound, followed over 10 milliseconds later by the onset of an unusually strong, diffuse, spectrally-correct reverberant field. The result is an improvement in not only spaciousness and sense of envelopment, but also timbre and even clarity.

Briefly we believe we've developed a speaker that forges into new territory as far as working with, rather than against, the room; and with, rather than against, the ear/brain system. Of course those aren't the only things we pay attention to, but they're what set the Zephrin 46 apart. That plus its elegant and memorable form-follow-function shape.

Type: Late Ceiling Splash (LCS) augmented two-way floorstander.

Driver complement: Four 6" woofers, one 1" compression driver, four 1" domes.

Bass loading: Bass reflex, two independent chambers, each with two pluggable ports.

Treble adjustment: High quality external resistors allow user-adjustable top-end "tilt".

Dimensions: 42" tall x 16" wide x 19" deep, 80 pounds.

System Impedance: 8 or 32 ohms, user-selectable, tube-friendly in either configuration

Efficiency: 92 dB/1 watt. Voltage sensitivity (relative to 2.83 volts input) is 92 dB in 8-ohm configuration, and 86 dB in 32-ohm configuration.

Power Handling: 400 watts RMS thermal.

Typical in-room bandwidth: Upper 30's to 20 kHz.

Price: $5500/pair + shipping.

Optional beryllium diaphragm compression drivers: $1000/pair.

Zephrin 46 is available in choice of oak, maple, or walmut wood veneers. Custom wood veneers, custom paint, and grilles are additional cost.

"The result is remarkably unremarkable. Unnaturally natural. Indescribable only in as much as there’s nothing to describe that’s not the thing being described."

"If the Zephrin was matched and tuned in my room as I would like, it might become a to-die-for project at the price level."

As music lovers, what are we looking for in a high-end audio speaker? The closest approach we can reasonably make to recreating the perception - the feeling - of being in the presence of live music. Timbre, inner detail, and dynamic impact are all a part of this. But perhaps the most elusive aspect is image density - that is, the perception that the sound-source images we hear in space have body and weight to them. This goes beyond the pinpoint imaging of a good mini-monitor, and beyond the rich sense of envelopment of a good omnidirectional system, though it includes aspects of both.

The key to recreating sound images that feel like the real thing is to set up a powerful, diffuse, spectrally correct, fairly late-arriving reverberant field. When done right, the ear-brain system interprets this reverberant energy as confirmation of the imaging cues in the first-arrival sound and we perceive those sound images as having realistic density.

The Dream Maker LCS system uses a high quality pair of main speakers to generate the desired first-arrival sound, and then a pair of separate, dedicated, highly directional upfiring array modules adds the extra spectrally-correct reverberant energy, with the required time delay coming from the long path this energy takes bouncing off the ceiling before reaching the listening position. The Late Ceiling Splash configuration is the invention of James Romeyn, and could be considered an advanced evolution of the controlled-pattern bipolar configuration first seen in the original award-winning AudioKinesis Dream Maker.

The separate LCS modules allow a great deal of placement flexibility, along with spreading out the physical location of the bass sources within the room, which improves the in-room bass smoothness.

Type: Four-piece Late Ceiling Splash (LCS) system.

Driver complement per side: One 10" studio-quality woofer; four 5" woofers; three 1" polymer-diaphragm compression drivers on low-coloration waveguides.

Bass loading: Bass reflex, each enclosure tunable via two pluggable ports.

Treble adjustment: High quality external resistors allow user-adjustable top-end "tilt".

Main module dimensions: 42" tall x 15" wide x 17" deep, 97 pounds.

LCS module dimensions: 13" tall x 14" wide x 20" deep, 45 pounds.

System Impedance: 8 or 32 ohms, user-selectable, tube-friendly in either configuration

Efficiency: 92 dB/1 watt. Voltage sensitivity (relative to 2.83 volts input) is 92 dB in 8-ohm configuration, and 86 dB in 32-ohm configuration.

Power Handling: 500 watts RMS thermal.

Typical in-room bandwidth: Mid 30's to 20 kHz.

Price: $8800/pair + shipping.

The main modules and LCS modules can be purchased separately, so the system can be acquired in stages. The main modules are $5900/pair, and the LCS modules $2900/pair, + shipping. Choice of wood veneers oak, maple, and walnut. Custom veneers and paint additional cost.
