Polk Audio Monitor XT90 Dolby Atmos Height Speakers in Black (Pair) - 300148-01-00-005

Polk Audio 300148-01-00-005 Monitor XT90 Dolby Atmos Height Speakers in Black (Pair)

The Polk Audio 300148-01-00-005 Monitor XT90 home theater height module speakers bring Dolby Atmos and DTS:X overhead effects to a compatible surround sound system and are sold as a pair. Designed to reflect sound off the ceiling, these Monitor XT Series modules add vertical detail to movie and game soundtracks. Place them atop supported Monitor XT20, XT60 or XT70 speakers, on a shelf, or on the wall using built-in keyhole slots. External amplification comes from a compatible AV receiver offering at least seven channels and the required surround-format support.

Key Features

Dramatic 3D Sound

Raise your home theater to new heights with planes flying overhead, special effects and environmental ambience that expand the listening experience beyond ear-level speakers alone. The modules use ceiling reflections to introduce overhead information into the existing sound field, with Dolby Atmos, DTS:X and DTS Virtual:X compatibility for multidimensional movie and game audio.

Flexible Placement and Built-In Keyhole Slots

Build around your existing Monitor XT20, XT60 or XT70 speakers: these are the specifically supported models for speaker-top placement. A shelf provides another placement option, while integrated keyhole slots let you choose a wall-mounted installation instead. These choices let you plan the height-channel addition around your current speaker arrangement.

Receiver Compatibility and 30-100 Watts Per Channel

Before adding height channels, check both receiver processing and amplifier specifications. Use a compatible AV receiver with 4- or 8-ohm outputs, at least seven channels, and Dolby Atmos or DTS:X support. Recommended amplifier power is 30-100 watts per channel, and sensitivity is 89 dB at 2.83 V/1 m. Alternative vintage-receiver use is limited to units equipped with DSP and ambience-speaker outputs.

Braced MDF Cabinets and Precision-Fit Grilles

Internal bracing helps limit MDF cabinet resonance as the drivers reproduce soundtrack effects. Nickel-plated 5-way binding posts provide the connection to external amplification. Removable, precision-fit grilles let you display the drivers or keep them covered, while the Matte Black finish defines the cabinets' appearance in your home theater.

4 in Bi-Laminate Paper Woofers

Each module uses one 4 in bi-laminate paper woofer to reproduce its height-channel audio. Total frequency response is 94 Hz to 22,000 Hz; the separately specified -3 dB range is 164 Hz to 17 kHz. The pair supplements an existing home theater with overhead information rather than serving as a complete surround speaker system.
