Atlantic Technology IW-155 LCR THX In-Wall Speaker

IW-155 LCR THX Ultra 2 Front LCR Bezel-less In-Wall Speaker

The IW-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 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 Atlantic's other THX-certified in-wall speaker, the IW-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. Because the IW-55-LCR is an Atlantic Technology M-T-M configuration (midrange - tweeter - midrange) it means that it can be flexibly placed without compromise along the front of any cinema - or used in higher end 2.1 stereo applications as well.

As with all thoroughly designed Atlantic in-wall's, 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.

Feature List:

  • Sonic performance is a perfect match with our other Atlantic THX in-walls
  • Easy horizontal mounting between standard 16"-on-center, 3 1/2"-deep wall construction
  • Ultra-thin bezel and magnetically attached grille for ultimate stealth
  • Backbox (IN-BOX-155) sold separately, required for THX-certified performance
  • Boundary Compensation and High Frequency sound-optimization controls

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

If you are looking for a more 'dedicated' application for the best reproduction, then you can also upgrade the fantastic IW-155-LCR further with the use of the optional IN-BOX-155. This back box provides the proper enclosure volume for optimum THX-certified woofer response, and minimizes acoustic bleed-through from one room to another.

This alongside it's sheer stunning performance acoustically, underlines the speaker’s THX certification, and is your assurance that the IW-155 LCR belongs in the very highest category of precision, high-performance audio devices.
