Adastra Speakers (Indoor)

Indoor speakers play background music and announcements in offices, shops, cafés and homes. This page holds Adastra speakers, including 100V line and 8 ohm models in ceiling, wall, column and pendant styles, bookshelf pairs, Bluetooth and active speaker sets, fire-rated models and packages that pair speakers with an amplifier. The BC6V-W (952.716UK) switches between 100V line tappings and 8 ohm operation with a rotary selector.

Choosing Adastra Speakers (Indoor)

Decide between a 100V line system and low impedance first, then the mounting, then whether a ready-made package suits.

Line voltage or low impedance

On a 100V line system, tappings set how much of the amplifier's power a speaker takes: the 952.168UK quick fit ceiling speaker is tapped at 1.5W, 3W and 6W, and the BC6V-W (952.716UK) has a rotary selector for 100V line tappings or 8 Ohms operation. Low impedance pairs such as the BC Series 100.907UK run at 8 Ohm from a stereo amplifier.

Ceiling speakers

KV-T series speakers such as the 952.280UK are ABS 2-way 100V ceiling speakers with a magnetic frameless grille and glass-aramid drivers. The 952.260UK low profile model fixes into suspended or false ceilings with dog-ear mounts, and its grille can be painted to match the decor. For washrooms and food preparation areas, the 952.138UK is a 3" metal ceiling speaker with a water-resistant coated paper cone.

Wall, column and pendant

BM-series wall speakers such as the 952.502UK offer 100V or 8 Ohm operation on an adjustable steel bracket for walls or ceilings. SC series columns such as the 952.240UK are slim extruded aluminium units for discreet indoor use. Where ceilings are high, PS series pendants such as the 952.426UK hang on a 4.5m cable with a hook.

Packages and active sets

The 300.010UK compact 100V package pairs 5.25" metal ceiling speakers with a UM series amplifier that has USB, Bluetooth and an FM tuner, and the 300.102UK Smart Pack streams over WiFi to two 6.5" slimline ceiling speakers. The 953.164UK Bluetooth ceiling set pairs an active speaker with a passive one, so no separate amplifier is needed.

Frequently asked questions

What are Adastra speakers?

Adastra speakers are loudspeakers for background music and announcements in shops, offices, cafés and homes. Some run on a 100V line system so many speakers can share one amplifier, while low impedance pairs connect to a stereo amplifier. Indoor styles include wall, column, pendant and bookshelf speakers, plus Bluetooth sets. The range here includes wall speakers, column speakers, pendant speakers and speaker packages.

What are Adastra 100V line speakers?

Adastra 100V line speakers have a built-in line transformer, so several can share one cable run from a 100V line amplifier. Tappings on the speaker set how much amplifier power it draws, so a quiet area can run softer than a busy one. Some models also switch to low impedance operation. The range here includes column, wall and pendant speakers.
