“Entry-level” doesn’t apply
to its sound.
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.
