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.
