About the product

AI-Sonic S2 amplifiers. Designed in Finland by AI-Group.

Excellent sound quality, versatile adjustment features and can be connected to any system to play any speakers. Ai-Sonic S2 amplifiers are really hard to beat.

The ambitious goal was to design and implement an amplifier collection that offers the best possible sound quality in its price range. The work started by designing a unique cooling profile.

Maximizing cooling and minimizing the physical size of the devices continued with circuit board design. The locations of the components on the circuit board are carefully selected in order to achieve the smallest possible physical size of the amplifier and efficient cooling of the components.

Twice as much copper has been used in the circuit board compared to a standard car amplifier circuit board.

Three years have been spent selecting and testing the components of the AI-Sonic S2 amplifiers. By testing and auditioning numerous different parts and combinations of parts, the parts that form the best possible whole in their price category have been found.

All parts of AI-Sonic amplifiers are slightly oversized in relation to the power of the amplifier. Double power sources are used in larger models.
Level remote control available as an accessory. (Note: Works only when LPF is on.) The level control also has power, clip and interference status indicators. RMS POWER (2ohm) 12v 1%THD 2x105W
