-Frequency response is from -4dB @ 13 Hz to well beyond 24,000 Hz.
-Efficiency is 87dB.
-Impedance is 7 Ohms, nominal. Minimum impedance is 5 Ohms.
-Tweeter: Two 1" cloth domes. Each tweeter has a large-diameter vent on its pole piece and a big aperiodic damping chamber that imitates an infinite baffle loading. The size of the pole piece across the driver surface area, increases linearity and power handling, while having exemplary frequency response. The tweeters are manufactured on a special production line under laboratory conditions.
-Mid-bass: Twelve 6" polypropylene, double-magnet driver, with a 3" voice coil diameter. Extremely rigid structural physics and the piston-like action of this driver produce exceptionally quick transients and a complete absence of coloration. These drivers are run full-range in four independently tuned transmission lines. Each transmission line contains three drivers in a pressure driven design, mounted front to back. The rear drivers reduce backpressure on the baffle-mounted drivers, simulating a free air resonance while simultaneously increasing linearity and power handling.
-Bass: Nine 12" woofers loaded in three parallel chambers. Each chamber consists of three woofers firing in a pressure driven configuration. The rear drivers reduce backpressure on the baffle-mounted drivers, simulating a free air resonance while simultaneously increasing linearity and power handling. The rear drivers are vented out the back of the enclosure through 4" ports.
-Enclosure: The extremely heavy enclosure becomes slightly wider as the speaker gets deeper on the bass enclosure and slightly narrower on the high frequency section. This minimizes parallel wall interactions, while increasing rigidity and stability.
-Internal wiring is manufactured by Transparent Audio.
-Single Cardas rhodium binding posts.
-The crossover for the tweeter is hard wired. We utilize Hovland MusiCaps and Vishay resistors.
-Damping material or stuffing is Acousta-Stuff, a nylon polyamide loose bulk fiber that is tri-lobal (instead of round) and multi-directionally crimped so that the strands interlock to form a very cohesive mass that does not require support and will not settle.
-The grills are made of an extremely transparent material that is stretched over a thin steel frame. They attach via magnets that are buried under the surface laminate, allowing the speakers to look as finished with the grills on as with them off.
-Black Italian granite is utilized.
-Special designed castors are permanently mounted to the base and are an integral pert of the design.
-The footprint is 15" wide on the baffle, 18" wide on the back panel. It is 36" deep, and 76" tall
-Net weight, per loudspeaker, is 790 pounds. |
