Atlantic Technology IW-155SR (Pair)

£1,400.00

High Performance In-wall Surround and Rear Effects speaker for large theater installations (Pair)

The IW-155 SR is a premium-performance in-wall surround speaker that delivers spacious, enveloping surround effects for top-grade home theater systems. Its ultra-thin bezel and magnetically attached grille 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.

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.

It features an innovative dual-concentric driver design capable of filling the listening area with three-dimensional lifelike theater sound, whether the system is based on non-directional ambient sound or object-based positional audio.

The IW-115 SR features dual 4.5” woofers with concentric 1” silk dome tweeters mounted in a non-resonant medium density fiberboard (MDF) baffle. Using MDF for the baffle instead of the thin, vibration-prone plastic used in ordinary in-wall speakers gives the 155 SR’s drivers a far more solid “acoustic footing” from which to launch their sound, resulting in cleaner output and greater resolution of low-level details.

The speaker features switchable dipole/bipole mode. Use dipole mode for diffuse-field surround sound, such as 5.1 Dolby True HD and 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.

The thin bezel grille is magnetically attached to the frame and can be easily removed or re-attached. The grille can be painted to match virtually any décor so the 155SR will blend into the room and become virtually invisible.

Feature List

  • Front panel mounted dipole/bipole switch
  • Non-resonant MDF baffle and gold plated connectors
  • Sonic performance is a perfect match with our other Atlantic In-walls
  • Ultra-thin bezel and magnetically attached grille for ultimate stealth

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 theater.

We 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.

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.
