Atlantic Technology IW-155 SR THX In-Wall Surround Speaker
An absolute must if you want to guarantee lifelike three-dimensional surround performance!
The new Atlantic Technology IW-155 SR is a premium-performance in-wall surround speaker that delivers spacious, enveloping surround effects for top-grade home theater systems.
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.
The speaker features switchable dipole/bipole mode: Use the dipole for diffuse-field surround sound, such as Dolby Tru HD or bipole mode for precise object-based surround formats such as Dolby Atmos. Either mode will fill a large home listening area with lifelike, dramatic surround effects. We generally recommend setting the switch to dipole mode when you are running a standard set-up . This dipole mode puts the two driver arrays out of acoustic and electric phase with each other so in the near field, their outputs cancel, resulting in a very non-locallizable sound field. This is ideal for reproducing non-directional sound effects.
The IW-155 SR is a perfect surround speaker whether you are running a 5.1, 7.1 or 9.1 theater or an enhanced Dolby Atmos or DTS-X cinema system. When installing in a Dolby Atmos or DTS-X home theater, set the IW-155SR to Bipole mode (the speaker arrays in phase with each other) The positional audio in Dolby Atmos and other object based systems requires precise sound localization from the surround speaker. Bipole speakers deliver very definitive imaging and outperform Dipole speakers in these instances.
The front mounted switch makes it easy to change for personal preference as well. Its ultra-thin bezel and magnetically attached grille makes it particularly inconspicuous when installed.
