It concentrates effortless functionality, advanced digital processing and powerful amplification within a beautifully portable high performance system, designed to draw a deceptively big stereo sound from all Bluetooth devices within seconds anywhere in the home.

Convenient and easy-to-connect

Employing superior audio architecture to get the most from higher quality Bluetooth aptX streams, the compact and curvaceous S150 will pair instantly with compatible devices to deliver CD-like sound quality, fuss-free and wherever it’s needed.  For added convenience, iOS devices may be charged via the USB input and analogue devices can connect through a 3.5mm stereo jack. Engineered with the precision shared by all Monitor Audio designs, the curvaceous S150 will exude quality in a choice of white or black finishes from shelf or table-top, or from a wall via one of our optional ¼” UNC mounting kits.

Design for Sound

The super-compact S150 is constructed from a high-tech mineral-filled polymer for excellent rigidity and damping to form the ideal acoustic environment for a cluster of four specialised drivers, comprising a proprietary gold dome C-CAM tweeter flanked on angled baffles by dual 3”-CAM metal cone bass drivers augmented by a rear-firing Auxiliary Bass Radiator (ABR).

The C-CAM drivers are powered directly by dedicated class-D amplifiers, generating forty watts in total, fed by a high resolution DAC and optimised by intelligent digital processing to ensure the ideal balance of detail, dynamics and dispersion within Bluetooth range.

Brimming with Monitor Audio’s flagship technologies, the beautifully specified, space-efficient Airstream S150 delivers an irresistible blend of style, performance and effortless convenience to music lovers seeking excellent design innovation with instant audio gratification.
