Db-99 MkII SPECIFICATIONS
SYSTEM TYPE: Three-way high- sensitivity speaker using a booster-stage solid- state amplified bass system, suitable for SET amps as well as larger tube and solid state amps of any power range. Sonic Emulation design enables the booster amp to take on the sonic characteristics of the driving amp, with no alteration of timbre. The high dynamic range enables both music and home theater sources to excel at realistic sound reproduction, with unbelievable slam, jump factor, and emotional connection to the music.
SENSITIVITY: 98 to 99 dB measured in room, using one watt at one meter.
IMPEDANCE: 8 ohms nominal; flat impedance curve ensures SET amplifier stability.
FREQUENCY RESPONSE: 21Hz to 25kHz +/- 3dB.
BASS SYSTEM: 10" Excel “Super-Duty” woofer with lightweight magnesium cone, 2" high-temp voice coil, vented magnet design, and Low Distortion Motor. Triple-chambered transmission line enclosure with venturi-shaped rear firing port, critically damped with acoustic foam and Dacron.
BOOSTER AMPLIFIER: 300-watt solid-state secondary-stage amplifier using Class A/B bias, Hi-Current power supply with large transformer and filter capacitors, Auto-turn on feature and Bass Volume Control knob. Enables bass-to-room matching.
MIDRANGE DRIVER: 7" cast frame driver employing exotic cone made from carbon, Kevlar, and cellulose acetate pulp using a ceramic binder. The extremely light-weight cone is very rigid and externally damped, ensuring very high transparency exceeding electrostatic or ribbon drivers. A large edge-wound ribbon voice coil allows very high power handling with very fast transient speed. A 2kg motor assembly delivers a sensitivity of 100dB and low distortion. This incredible driver is mounted in a terminated transmission line enclosure that is critically damped using thick felt, acoustic foam, and Gradient Density stuffing to absorb the backwave and cavity resonance.
TWEETER: A European 1” fabric dome tweeter is mounted in a 2" short wave-guide type horn and uses an ultra-light diaphragm and large Low Distortion Motor assembly for very high sensitivity. Ferro-fluid liquid cooling enables high power handling with ultra-smooth response at any volume level.
SUPER-TWEETER OPTION: Available as an accessory, a 3” aluminum foil ribbon super-tweeter extends the response to 100kHz (-6dB). Contained in the painted pyramid module are: crossover, volume control potentiometer, and umbilical cable for connection to the main speaker binding posts. Sonic improvements include more “air” around instruments and superior image focus; vertical height imaging and transient response improvements attain a level of realism not obtainable by any other design. Priced at $2,000 per pair, this unit can be used with any speaker.
AMBIENCE RETRIEVAL SYSTEM: A rear-firing 1” fabric dome Vifa/Scanspeak mid/tweeter generates the correct depth found in the recording and is fed by a specialized Ambience Derivation Circuit with control knob for adjustment of volume level and depth-of-field. The true depth of the concert hall is now attainable.
POWER REQUIREMENTS: As little as 8 watts may be used, with full dynamics! 200 watts maximum continuous power, with 500 watts peak.
DIMENSIONS: 43" High x 17" Deep x 8" Wide at top x 13" Wide at bottom.
WEIGHT: 115lbs, 130lbs packed in heavy-duty hex crate for shipping.
