Systemline’s Airway in-ceiling speakers are AirPlay capable, but much like Russounds AirGo outdoor speaker they require an AirPort Express for AirPlay functionality.
The speakers (they come in a stereo pair) offer an unobtrusive design that tucks away into a ceiling or wall. The AirPort Express works with the speakers by feeding an optical cable from the AirPort Express into a supplied wall plate. Next, a CAT5 cable runs from the wall plate to the speakers. Power is supplied to the speakers from the wall plate.
Speaker control is via an iOS app.
For $948 (£599) you get two speakers, a pre-configured AirPort Express, wall plate, power supply, digital and CAT5 cables.
Release date unknown.
