SC203 Stereo Loudspeaker System

When a small footprint – but a big sound! – is what you're looking for, the SC203 becomes one of those few examples where small also means powerful. 

When using woofers in small desktop speakers, some special considerations have to be taken into account. To meet the demands of a precise reproduction in the low frequency region, we've developed a 3" woofer coupled with a 1" voice coil capable of handling a longer linear excursion. With a 16 mm-height voice coil, a linear, back and forth, swing of ±5mm is easily achieved. However, this requires an appropriate multilayer paper membrane material that is capable of withstanding such rigorous use while maintaining consistency.

A passive radiator – which you could simply think of as a passive speaker that moves through the force of air – located at the backside of the SC203, reinforces the reproduction of low frequencies and allows the speaker response to go down as low as an impressive 62Hz (-3dB) with very low distortion.

Each SC203 setup is configured as a 2-way master-slave system, and features four power amplifiers. Each woofer and tweeter gets its own dedicated 30W PWM amplifier with separate filter section for precise control. And for optimal connectivity, the SC203 houses three inputs – analog RCA, digital optical and USB – which will allow you to conveniently connect a wide range of sources. Furthermore, a volume controlled subwoofer output lets you connect an additional subwoofer (TS107 und TS108) to the master speaker and create a powerful 2.1 system. A DIP switch located at the speaker's back panel allows you to select the SC203's to work as "satellites" from 80Hz and upwards, or as a full range units.
