AudioKinesis Jazz Module 2.0 (front half of Dream Maker LCS)

Edit 18 June 9:23 MDT: Seller is happy to ship your new speakers worldwide to any location with carrier service (earlier wrongly specified USA only). The stars have aligned for a once in a lifetime chance to bid on this rare eight month old AudioKinesis Jazz Module 2.0 by Duke Lejeune, meeting all AG criteria for mint condition, from a certified AK dealer, with full warranty as new. This pair has solid walnut front baffle with round-over corners (see image), a $1k/pair extra cost upgrade, hence the $6k/pair MSRP (the standard cost veneered baffle has square corners). JM 2.0 is refinement of Duke’s legendary original Jazz Module. JM 2.0 is also the front half of the ground breaking “Dream Maker LCS” employing Late Ceiling Splash reverberant field theories of Dr. Floyd Toole and Dr. Earl Geddes. Original JM was the front half of the original Dream Maker, which won TAS Golden Ear Award in 2008. Dealer/seller will deliver your new speakers to Duke who lives twenty-five minute drive north, who will crate and ship your new JM 2.0 to any point on the globe (buyer pays actual shipping/insurance cost). Original JM is a cult classic and one of the most highly desired loudspeakers. Both Original JM and JM 2.0 employ special input binding posts for a wide range of treble output adjustment (open posts = minimum, shorted posts = maximum, or resistors = in-between). The horn in this system acts as wave-guide to ideally match both driver radiation patterns in the crossover range. Years ago Duke LeJeune worked with Dr. Earl Geddes, wave guide patent holder and Distributed Subwoofer Array expert. JM 2.0 rear corners have large 45-degree angle. Compared to original JM, this 2.0 version employs more highly refined wave guide with increased radiation control and rear-firing compression driver in small round wave guide; both features improve spatial qualities. Also, JM 2.0 rear ports are strategically placed to emit mid-range from the mid bass, to further increase reverberant field output. Sale includes four plugs for air tight seal of the system’s four ports (two per speaker). Users minimize their room’s bass mode effects by running all four ports open, all sealed, or any combination thereof. But there’s more: this system has a special binding post pair for SS or tube “transfer function.” In a nutshell, it works! Short these posts for tubes, or open them to imbue SS amps with much of what makes tubes so desirable: increased image density and spatial effects, musical rightness, and general listening pleasure. If that’s not enough, this system can easily be driven by 30W tube amp, even less depending on application. Our 2013 Rocky Mountain Audio Fest Show demo was a smashing success with Atma-Sphere 30 watt OTL. JM 2.0 sensitivity is low 90 dB range, with flat 8 Ohm impedance above the bass range, 6 Ohm minimum, and easy phase angles. Conversely, high quality pro sound drivers allow up to 500W SS. Bass cutoff is in the high 30 Hz range while treble extends to a true 20kHz. Long term pride of ownership results from a wide array of user-defined adjustments for any listening room, spectral preference, or partnering components. There is absolutely no computer learning curve, no screen, no keyboard, and no hardware to re-boot, ever. All tuning adjustments are physical, electro-mechanical, and easily repeatable. JM 2.0 approaches the transparency of the world’s best electrostatic loudspeakers, has superb wide range dynamic punch, no “cupped hands” effect common to horns, and the industry’s widest range of user-defined adjustments. After eight months of continuous use seller detects absolutely no audible crossover artifact, where the world’s best controlled-directivity systems such as this have the edge over systems lacking such feature. Seller is full time music/audio professional with more hands on experience with this speaker than anyone else, and delighted to reply to any concern pre or post sale, generally available for twelve hours seven days per week, or off hours for overseas buyers.
