System includes: (1) IWTS-8eSUB THX Ultra Dual 8" Woofer Assembly, (1) SA-380 THX Ultra Mono Subwoofer Amplifer, and (1) IN-BOX-8e-SUB Wood Enclosure.
IWTS-8e Subwoofer Assembly
Each braced MDF enclosure accommodates a dual 8-inch long-throw woofer assembly, providing roughly the same cone area as a single 12-inch woofer, but with better control and lower distortion. These unique drivers sport a stiff and well-damped Coated Composite Molded Graphite cone, with an unusually strong cone-reinforcing concave dust cap. The vented eight-pound motor and 1.5-inch vented multi-layer voice coil are more typical of those found on a 15-inch driver. Additionally, the baffle is treated with Atlantic's exclusive Resonance Damping Treatment (RDT) to reduce unwanted baffle resonance for clear, articulate bass.
SA-380 monoblock amplifier
The SA-380 is capable of delivering 380 rock-solid RMS watts for the reproduction of exciting, authoritative theater bass. Its linear power discrete Class G circuitry delivers 380 watts RMS and 550 watts short-term peak power. The design uses audiophile-grade components, including a high-current custom-wound low-hum toroidal transformer. Class G design means the power supply is in dual mode in operation, one for long-term operation, and one for short-term very high power peaks.
Servo-control circuitry - This circuit monitors the woofers' performance. If the servo control detects driver distortion it immediately corrects it, resulting in very high output levels at unusually low distortion levels. A 2-position phase switch and THX-reference click-stop on the level control make operation easy and effective.
IN-BOX-8e sub enclosures
Each Atlantic Technology Sub 8e in-wall enclosure is 81 inches tall, 14-1/2-inches wide and 3-1/2 inches deep, with a 17-13/16 x 9-3/8 inch cut-out dimension for the woofer module. Designed for installation before the sheet rock goes on, only a discrete grille is visible at knee-level in the room. While the grill extends 1-1/2 inches into the room to accommodate the high excursion of the woofers, its smoothly radiused compound curves make it very inconspicuous.
