Its discreet, customisable appearance with magnetically attached white or black front grille makes it the perfect addition to the SI SERIES toolbox. A specially developed, multi-stiffened steel back can guarantees complete freedom from resonance. A front-operated 100/70 V transformer with bypass option and detailed equalisation via DSP ensure the highest possible sound quality.
Subwoofer models such as the SI SERIES S210 V or FINEO FO S112 (F) are available to support the bass range.
