Details
IWTS-155 LCR
The IWTS-155 LCR is the perfect answer to the seemingly contradictory demands of no-compromise performance and the ability to fit horizontally between standard 16"-on-center studs. This system represents a combination of superlative audio performance, simple installation, and innovative features that are unmatched by virtually any other custom-installed system.
This THX-certified (pending) front-channel speaker forms the heart of a top-performance home theater system. It is a 2-way system with a two long-excursion 5 1/4” woofers, and the very latest version of Atlantic’s exclusive 1” Low Resonance Tweeter (LRT™).
Use the 155 as a center channel speaker with either of Atlantic's other THX-certified in-wall speakers, the IWCB-727 or the IWTS-30 LCR. Because of its ability to fit horizontally between standard stud spacing, the 155 makes a perfect center channel match for these speakers, with absolutely no dropoff in performance or output.
Alternately, you can use three 155's across the front LCR stage--either vertically, horizontally, or a V-H-V combination--for a virtually perfectly, seamless front theater sound.
Front Panel Controls :
- HF level—Adjusts tweeter’s output for varying room acoustics
- Boundary—Adjusts upper-bass/lower-mid response to correct for “boundary gain” when speaker is too close to corner
The optional IN-BOX-155 back box provides the proper enclosure volume for optimum THX-certified woofer response, and minimizes acoustic bleed-through from one room to another.
Separate GFR-155 grille/frame—Grille/frame assembly is sold separately from speaker portion, to maximize installation scheduling convenience.
This speaker’s THX certification is your assurance that the IWTS-155 LCR belongs in the very highest category of precision, high-performance audio devices..
