Atlantic Technology - IW-155LCR-S - THX In-Wall Speaker (Single)

Atlantic Technology - IW-155LCR-S - THX In-Wall Speaker (Single) 

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 GFR-155 grille/frame assembly (required) is packaged and sold separately for maximum installation/scheduling flexibility


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.

  • 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
  • Backbox (IN-BOX-155) sold separately, required for THX-certified performance
  • Boundary Compensation and High Frequency sound-optimization controls
