Adastra Ceiling Speakers

Adastra ceiling speakers fit flush into a ceiling for background music and announcements. This page holds single speakers, such as the 100V line KV-T, CC Series and Metal Quick Fit models and the 8 ohm CD and SL series, and complete Adastra packages that pair ceiling speakers with an amplifier: Smart Packs, Compact and Commercial 100V packages, add-on packages, WiFi multiroom systems and Bluetooth sets.

Choosing Adastra Ceiling Speakers

First decide between single speakers for an amplifier you already have and a package that brings its own amplifier, then match the line type and driver size to the room.

Line-transformer models

The KV-T Series, such as the 952.281UK (6.5", 30W), has three 100V volume tappings on a 4-core cable and an 8 ohm option that bypasses the transformer. The 952.178UK Metal Quick Fit is a black 135mm speaker with 1.5W, 3W and 6W tappings, and the 952.205UK fire dome speaker is EN54-24 certified, with four tappings from 0.75W to 6W and fire-resistant cable rated to 95°C.

Two-way and stereo models

The KV Series 125.105UK, 125.106UK and 125.108UK are two-way ABS speakers with glass-aramid drivers, a coaxial dome tweeter and a magnetic frameless grille, rated 40W, 60W and 80W. SL Series slimline speakers are supplied in pairs, such as the 3" 952.545UK and the 6.5" 952.548UK, and the 952.537UK plays left and right stereo channels from a single ceiling point.

Packages with an amplifier

The Smart Pack Small 300.106UK pairs a DM25 100V mixer amplifier with 4 flush-mounted speakers, and the Smart Pack Medium 300.107UK a DM40 with 8. Compact 100V packages such as the 300.011UK use UM series amplifiers with USB, Bluetooth and an FM tuner. Add-on packages such as the 300.077UK run extra mini speakers from a US series slave amplifier fed by the 100V line. Smart Pack Multiroom sets, such as the 300.103UK, stream over WiFi under the control of an Android or iOS app.

Frequently asked questions

How do Adastra Bluetooth ceiling speakers work?

Adastra Bluetooth ceiling speakers pair with a phone or tablet and play its music through speakers fitted flush in the ceiling. In an active and passive set, the active speaker holds the Bluetooth receiver and drives its passive partner. Larger systems use an amplifier with a built-in Bluetooth receiver instead. The range here includes Bluetooth speaker sets and amplifier packages.

What is an adjustable ceiling speaker?

An adjustable ceiling speaker has a tweeter that can be angled to point high frequencies towards the listening area. This helps when the speaker cannot sit directly above the listeners, for example off to one side of a seating area. Treble is more directional than bass, so aiming it can improve clarity. The range here includes two-way speakers with directional tweeters.

What is an Adastra sound system?

An Adastra sound system is a ceiling speaker package that pairs an amplifier with speakers matched to it, ready for background music and announcements. Smaller sets suit a single room, while 100V packages can run many speakers across shops, offices and cafés. Some packages stream over WiFi and are controlled from a phone app. The range here includes Bluetooth, commercial and multiroom packages.

When is an eight-inch Adastra ceiling speaker the right choice?

An eight-inch Adastra ceiling speaker suits higher ceilings, larger rooms and music that needs more bass. Its bigger driver can carry sound to listeners further away, so speakers can often be spaced more widely. Smaller drivers usually suit low ceilings and quieter areas such as offices. The range here includes eight-inch two-way models in several series.
