The SoundTube XT550 is a 2-way in-ground outdoor loudspeaker designed for background music, foreground audio, and paging in commercial and residential outdoor environments. Featuring a 5.25-inch polypropylene woofer, 1-inch aluminum dome tweeter, and SoundTube BroadBeam® technology, the XT550 provides 360° horizontal coverage for consistent sound distribution across outdoor listening areas.

Designed for permanent outdoor installations, the XT550 features a sealed, weather-resistant enclosure with UV-, scratch-, and chlorine-resistant components. Its landscape-friendly design is available in granite green or sandstone to blend into gardens, landscaped areas, patios, parks, hospitality properties, and other outdoor spaces.

The XT550 supports 25V, 70.7V, and 100V distributed audio systems and also provides a 4Ω direct/bypass option, giving system designers flexibility for both constant-voltage and low-impedance installations.

BroadBeam 360° Outdoor Coverage

SoundTube's BroadBeam waveguide technology provides 360° horizontal dispersion, allowing the XT550 to distribute sound around the loudspeaker rather than concentrating coverage in a single direction.

This omnidirectional coverage makes the XT550 well suited for outdoor areas where listeners may be positioned on multiple sides of the speaker.

5.25-Inch Two-Way Speaker Design

The XT550 combines a 5.25-inch polypropylene woofer with a 1-inch aluminum dome tweeter in a 2-way design.

The crossover operates at 3.0 kHz, while the port configuration allows the system's low-frequency performance to be adjusted for the installation.

With the port open:

• 49 Hz–22 kHz frequency response (-10 dB)
• 61 Hz–9.5 kHz frequency response (±3 dB)

With the port closed:

• 62 Hz–22 kHz frequency response (-10 dB)
• 101 Hz–12 kHz frequency response (±3 dB)

25V, 70.7V, 100V or 4Ω Operation

The XT550 can be used with commercial distributed audio systems or compatible low-impedance amplifiers.

Supported configurations include:

• 25V
• 70.7V
• 100V
• 4Ω direct

A weather-resistant tap selector provides convenient transformer configuration, while the bypass position allows direct 4Ω operation when required.

60W Continuous Power Handling

When operated in its low-impedance configuration, the XT550 is rated for:

• 60W maximum continuous RMS
• 120W maximum program power
• 4Ω nominal impedance

System sensitivity is rated at 83 dB at 1W/1m and 86 dB at 2.83V/1m.

Need a Larger Outdoor Speaker?

Need a larger in-ground speaker with higher power handling and extended low-frequency response? See the SoundTube XT850 8-Inch In-Ground Outdoor Speaker, featuring 100W continuous power handling and frequency response down to 38 Hz (-10 dB).

Why Choose the SoundTube XT550?

The SoundTube XT550 combines 360° BroadBeam coverage, 25V/70.7V/100V distributed audio compatibility, 4Ω direct operation, and weather-resistant construction in an in-ground loudspeaker designed specifically for outdoor audio systems.

Its 360° horizontal coverage can help distribute music and paging throughout landscaped areas while its low-profile enclosure is designed to integrate more naturally into outdoor surroundings than a conventional surface-mounted loudspeaker.
