Atlantic Technology IWTS-4 LCR
The Atlantic Technology IWTS-4 LCR is our lowest-priced in-wall speaker but it borrows much of its technology and simplicity of installation from its more costly brethren.
This speaker uses a 6 ½” GLH (Graphite-Loaded Homopolymer) woofer for solid bass down to 57 Hz and Atlantic’s renowned 1” soft-dome Low Resonance Tweeter (LRT™). Because of its low crossover point, this remarkable tweeter allows the IWTS-4 LCR to deliver much wider midrange dispersion than conventional in-wall speakers for greater placement flexibility, without the severe acoustic and mechanical drawbacks of the so-called “pivoting tweeter.”
Here’s why: The woofer in conventional in-wall speakers handles too much of the midrange and woofers send out the midrange like a flashlight beam—pretty much only straight ahead, with very little sound side-to-side or up-and-down. So even if these speakers have a pivoting tweeter, that doesn’t really help, since it’s the woofer, not the tweeter, that handles the directionally-critical midrange frequencies.
What’s needed is a speaker where the tweeter, not the woofer, handles more of the midrange, because unlike woofers, tweeters spread their sound out over a very wide area.
Because of this, Atlantic has engineered an extremely sophisticated, high-performance tweeter (the Low Resonance Tweeter, or LRT™) for the IWTS-4 LCR, and it can play most of the middle tones as well, thereby relieving the woofer of having to do what woofers can’t do. Our LRT tweeter spreads out the midrange sound over a much wider angle than the woofer, so the IWTS-4 covers the entire listening area beautifully in both the midrange and treble, even when it’s mounted high up on the wall. This tweeter technology was originally developed for our In-Wall Closed Box series (retailing for up to $1000 ea.), but is now available in the IWTS-4 LCR, at a fraction of the price. We know of no similarly-priced in-wall speaker that can match its performance.
