Klipsch PRO-650T-LS

With its matte brown enclosure designed to blend into gardens, the PRO-650T-LS brings Klipsch’s acoustic expertise to a weather-resistant format. The American manufacturer incorporates the same technologies found in its indoor speakers, including the Tractrix horn, while also providing power flexibility that makes it compatible with both residential installations and professional sound systems.

A Tractrix horn adapted to open spaces

The 25 mm aluminum dome tweeter is coupled to a Tractrix horn specifically redesigned for outdoor use. This waveguide geometry, featured on Klipsch products for decades, improves efficiency and reduces distortion in the treble. The version built into the PRO-650T-LS extends horizontal dispersion to 105°, making it possible to cover a wide area without creating “dead” zones where the sound would be reduced. Whether moving around a patio or a pool, the tonal balance remains stable.

Bass and midrange are handled by a 16.5 cm driver with an IMG (Injection Molded Graphite) cone. This composite material, rigid yet lightweight, limits cone deformation at high volume levels, preserving low-frequency definition. Frequency response reaches 100 Hz at -3 dB, and extends down to 77 Hz with a 10 dB attenuation. For enhanced bass in large areas, Klipsch offers compatible outdoor subwoofers, such as the PRO-12SW-LS.

The 90 dB sensitivity and 100 W peak power handling guarantee a comfortable sound level, even across large properties, without placing excessive demand on an amplifier.

Flexible power options between domestic use and distributed installations

The PRO-650T-LS operates in direct impedance (8 ohms) or via an integrated transformer for 70 V and 100 V lines. This dual mode allows it to cover two use cases: simple connection to a conventional hi-fi amplifier, or integration into a distributed system where several speakers share the same power line over long distances, a common solution in hospitality, restaurants, or commercial spaces.I now have all the necessary information.

Klipsch PRO-650T-LS: landscape speaker

With its matte brown enclosure designed to blend into gardens, the PRO-650T-LS brings Klipsch’s acoustic expertise to a weather-resistant format. The American manufacturer incorporates the same technologies found in its indoor speakers, including the Tractrix horn, while also providing power flexibility that makes it compatible with both residential installations and professional sound systems.

Flexible power options between domestic use and distributed installations

The PRO-650T-LS operates in direct impedance (8 ohms) or via an integrated transformer for 70 V and 100 V lines. This dual mode allows it to cover two use cases: simple connection to a conventional hi-fi amplifier, or integration into a distributed system where several speakers share the same power line over long distances, a common solution in hospitality, restaurants, or commercial spaces.

The transformer offers several selectable power taps without tools via a rotary switch located on the rear (6.25 W, 12.5 W, 25 W, or 50 W at 70 V; 12.5 W, 25 W, or 50 W at 100 V). A silicone cap protects this switch from water and dust. For low-impedance installation, an 8-ohm bypass position routes around the transformer and uses the speaker’s full 100 W peak power.

Construction built for changing weather conditions

The glass-fiber-reinforced ABS enclosure features a UV-resistant treatment that preserves the plastic’s color and strength against sunlight. The rustproof aluminum grille resists corrosion, while the whole unit achieves an IP45 rating: protection against water spray from all directions and against dust. The speaker withstands temperature variations, rain, wind, and snow.

At 3.18 kg, the PRO-650T-LS remains easy to handle during installation. Its dimensions (210 × 224 × 280 mm) allow it to be concealed at the base of a flower bed or along the edge of a path. The matte brown finish blends naturally into a plant-filled environment, and the paintable surface makes it possible to match the speaker to a wall, fence, or garden furniture.

Installation without tools

Klipsch offers two optional ground stakes, one 25 cm and the other 46 cm (PRO-18-GS), which are pushed into the ground and hold the speaker in an angled position. Mounting is done with tightening screws, without drilling. A wall mount (PRO-1-SM) is also available for paved patios or façades. Once the speaker is fixed, it can be aimed to direct sound toward the desired listening area.

The PRO-650T-LS belongs to Klipsch’s Professional Series Landscape range. It sits alongside the PRO-500T-LS, a more compact model equipped with a 13 cm driver and a 30 W transformer, designed for smaller spaces or installations requiring several closely spaced sound points.
