Atlantic Technology IWTS-30 LCR Operating manual

The State of Our Art

The IWTS-30 LCR is our top-of-the-line in-wall theater speaker system, the best

we’ve ever made. Considering that Atlantic has been in the home theater speaker

business since 1989, that’s really saying something.

This system represents a combination of superlative audio performance, simple

installation, and innovative features that are unmatched by virtually any other

custom-installed system.

IWTS-30 LCR

This THX-certiﬁed front-channel speaker forms the heart of a no-compromise

home theater system. It is a 3-way system with a long-excursion 8” woofer, two

high-power 3 ½” midranges and Atlantic’s exclusive 1” Low Resonance Tweeter

(LRT™).

The midranges and tweeter are arrayed in a vertical M-T-M conﬁguration, in a

separate sealed enclosure, isolated from the woofer. The entire M-T-M assembly

rotates 90º, so that the tweeter-midrange array can be kept in the preferred

vertical orientation for optimum dispersion, even if you choose to mount the 30

LCR horizontally.

The M-T-M assembly can also be tilted up to 8º towards the listening area, so

no matter where the 30 LCR is mounted—above, below, or far to the sides of the

screen—its sound can always be directed precisely at the listeners for pinpoint

sonic imaging and localization.

The 3½” midrange driver is a proprietary Atlantic design that uses an over-sized

1” voice coil for outstanding power handling with virtually perfect driver control

for ultra-low distortion. Our 1” LRT tweeter has a damped rear chamber/heatsink

that allows the tweeter to cross over a full octave lower than an ordinary tweeter,

thus delivering much wider dispersion and more even sound coverage.

These advanced mid- and high-frequency drivers, combined with the rotatable-

tiltable M-T-M assembly, allow the IWTS-30 LCR to deliver an unprecedented

level of effortless, accurate sound, almost independent of where the speaker is

mounted.
