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. It is the perfect solution for professional desktops with a limited amount of physical space, for discerning home and gaming users, and for mobile studios during travel.

To further extend its flexibility, each speaker is provided with the FlexiPad, a rubberized pad that allows you to decouple the speaker from its base and angle it precisely at 0°, 7,5° or 15°.

Accessories include our SC203 Mounting Adapter, which enables you to mount your speaker directly on any microphone or speaker stand that features a 3/8" thread. Combining it with our threaded wall mount adapter it is possible to place your speaker directly on a wall. By placing the FlexiPad between the speaker and the mounting adapter you are further decoupling unwanted resonances, and can even better arrange orientation for upright positioning.

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.

After numerous careful tests, coated paper turned out to be the very best solution in order to meet this demand for low resonance, stability and transmission linearity. From then on, the entire construction design met all the necessary requirements that such small woofers usually entail, including having a chassis basket permeable to air in order to minimize distortions. The large driver magnet works as a powerful "engine" so as to keep the woofer stable, even in border areas.

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.

The extra compact Air Motion Transformer

The simple goal of bringing the sound quality, low distortion and high resolution of our now famous Air Motion Transformer tweeter to a much smaller format speaker took us on a many-month journey to find the perfect solution for the SC203. In the end, a new tweeter was born: the new µA.M.T.

This high resolution µA.M.T. delivers an astonishing high frequency resolution combined with extraordinary precision and clarity. The folded membrane of this high resolution µA.M.T. is only 400mm² in surface area, about less than half as our RS1 tweeter (which is used, for example, in the SC204 speaker). An integrated waveguide helps create an optimal dispersion pattern over a wide frequency range. No fighting over your sweet spot with this tweeter!

To complete the system, we've used strong neodymium magnets, coupled with a magnetic holder and membrane holder optimized for very low distortion values at the specified SPL. As usual with EVE Audio, no cutbacks were made to save money at the expense of a high quality tuned system.

Non-detachable loudspeaker grilles protect both, woofer and µA.M.T. tweeter against damage.

The Air Motion Transformer

Our tweeters base on the ribbon tweeter technology. We reinvented our own version of the A.M.T. which our speakers are well known for.
