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.
