The SC203
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 active-passive desktop speaker set, 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 active 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
We reinvented our own version of the ribbon tweeter technology which our speakers are well known for.
Understanding the Air Motion Transformer
The Air Motion Transformer (AMT) is a unique driver technology, distinct from other audio drivers. It utilizes a lightweight, hand-folded diaphragm that is thinly coated with aluminum. The current of the music signal flows through these conductive strands.
The diaphragm is placed in a powerful magnetic field leading to movement in the folds caused by the Lorentz force. Due to the opposing direction of the current the walls of each single fold work against each other. The air between the folds is squeezed in and out at a ratio of 1:4, compared to the 1:1 ratio of a regular dome tweeter.
This results in higher resolution and dynamics in the tweeter section, along with a very low distortion level, allowing superior sound quality with enhanced detail and clarity.
The SMART-knob

Powering On/Off: Standby Mode
Press and hold the control three seconds in order to put the monitor in Standby mode. The volume will decrease gradually while the LED ring lights up once around the Volume control. Afterwards, the LED on the right end will remain dimly lit and the power consumption is reduced to 1 watt.
Volume
The volume can be adjusted by turning the knob. Depending on the LED mode selected, the volume will be displayed as a dim/ bright circle or as a dim/bright point.
Mute
To put the monitor in Mute Mode, turn the volume control counter clockwise until you reach the minimum level. When the LED on the left end lights up dimly the Mute Mode is activated.
Settings
Press the SMART-knob once to enter the Settings menu. Here you can set different filters as well as the LED ring’s behavior. The LED of the currently active function blinks. Click the different filters above to find out more about them!
High Filter
The High-Shelf Filter helps you adjust frequencies above 3kHz in 0.5dB increments. You may need it in the following situations:
Distance from Speakers: High frequencies weaken as you move further from the speakers. If you sit far from the speakers, boost the high frequencies. If you're close, like in a desktop setup (about 1 meter or 3 feet away), you might need to reduce the high frequencies.
Room Acoustics: In a room with few reflective surfaces ("dead room"), boosting high frequencies can create a more balanced sound. Conversely, in a room with many reflective surfaces, reducing the high frequencies is advisable.
Adjust the High Filter accordingly and achieve the best sound quality based on your listening position.

Mid Filter
The Mid Filter is a bell filter centered at 1kHz. It allows you to boost or cut the midrange by up to +/-3dB in 0.5dB increments. Here's what you should consider:
Frequency Balance: The midrange is crucial for balancing lower and higher mid frequencies. Use the Mid Filter to fine-tune the balance between the fundamental and harmonic frequencies in your music.
Room Acoustics: The acoustics of your room can affect how midrange frequencies are perceived. Sound energy from the monitors may reflect off surfaces like walls, floors, and ceilings, altering the sound. Adjust the Mid Filter to compensate for these reflections and achieve a balanced sound.
The Mid filter is available on SC2070, SC3070, SC4070, SC3010 and SC3012.

Desk Filter
The desk filter allows you to boost or cut you low-mid frequencies in 0.5dB increments:
Narrow-Band EQ: Depending on the model the filter is centered between 160 and 200Hz. When turned down, it reduces the low-mid boost often caused by reflections from mixers and similar surfaces. Decrease the filter gain to lessen this effect.
EQ at 80Hz: When turned up, it enhances the lower frequencies, giving more punch to the sound.

Low Filter
The Low-Shelf Filter allows you to boost or attenuate frequencies below 300Hz in 0.5dB steps. Here's when to use it:
Attenuating Low Frequencies: If your room's acoustics cause a boost in low frequencies (due to room modes or speakers being close to walls), you can reduce them with the Low-Shelf Filter.
Boosting Low Frequencies: If the low frequencies are too weak, you can enhance them to achieve a balanced frequency response.
Adjust the Low-Shelf Filter accordingly to address any issues in the low frequency range caused by your room's acoustics.
