IWTS-155 LCR THX Ultra2  

Top THX-certified performance, between 2 x 4" studs!

sm_IWTS-155_LCR_front.jpg“The IWTS-155 LCR solves the dilemma of getting the best sound possible when you have to retro-fit between 16"-on-center studs. A perfect solution!—Peter Tribeman, President, Atlantic Technology

THX  Ultra2 Performance that fits everywhere!

The IWTS-155 LCR  is a premium-performance in-wall speaker that addresses the need for no-compromise performance with the flexibility to mount either horizontally or vertically in standard 16"-on-center stud-framed walls.It is a perfect solution for retro-fit applications and its small footprint makes it particularly inconspicuous when installed.

The 155's MDF baffle continues Atlantic's use of non-resonant baffle material for in-wall speakers, resulting in far better acoustic performance than speakers that use 'ringy' plastic or resonance-prone aluminum baffles or enclosures.

As a final touch, the 155 has two easily-accessible controls on the front panel (Boundary Compensation and HF Level) to adjust for varying placement and room acoustics situations.

The required GFR-155 grille/frame assembly is packaged and sold separately, so the grilles can be installed and painted during the construction phase, and the speakers themselves can be installed later on.

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.thm_IWTS-155_LCR_rear.jpg

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 drop-off 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:thm_IWTS-155_LCR_front.jpg

- 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.
