Description

The Adastra SC20V is a slimline column speaker made for indoor use, particularly where you want the audio present but the hardware kept discreet. The body is extruded aluminium with a white protective finish, fitted with a white metal grille and white plastic end caps, so it blends easily into most wall colours and interiors. It runs on a 100V line system, which makes it a practical choice for background music and paging across larger spaces like halls, foyers and retail areas.

Rated at 20W rms, the speaker carries a 100V line transformer with an integral rotary switch for tapping selection. That lets you set the power tap directly on the unit, so you can balance volume across a run of speakers on the same line without returning to the amplifier. The internal drivers give crisp, clear sound reproduction with a frequency response of 250Hz to 16kHz and a dispersion of 110 degrees, which keeps speech and music intelligible across a wide listening area.

Each speaker is supplied with mounting brackets, so you can fix it to a wall and adjust the angle to suit the room. The column format spreads sound over a broad horizontal area while keeping vertical spill down, which helps in rooms with hard surfaces. If you are building a 100V line setup, note that terms vary between regions: a 100V line system is sometimes called a constant voltage or high impedance system in US installations. The SC20V works within either description and is straightforward to wire in series with other 100V line speakers.
