IWTS-8e Sub

High Performance THX-Ultra bass--flush in 2 x 4" wall construction!

sm_IWTS-8e-Sub-SA-380.jpg“The system is authoritative, quick and superbly musical . . . incredibly deep bass.” — Darryl Wilkinson, Home Theater

THX Ultra-certified bone crushing bass--totally invisible
Great movie and music experiences build on a foundation of powerful, accurate bass. Achieving this kind of bass performance at home typically requires large, bulky, and obtrusive enclosures. In addition, the acoustic interaction between rooms and subwoofers degrades bass performance at the listening position. Now, with our in-wall subwoofer systems, you can get powerful, accurate, and authoritative deep bass from practically invisible THX Ultra® certified subwoofers that fit in standard 2 x 4 or 2 x 6 studded walls.

Requires separate SA-380 amplifier and In-BOX-8eSub

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.
