AA O103 SL – Active/Passive Speakers System

The AA O103 SL is a speaker system that is designed to be placed alongside the series of new Audio Alto open baffle speakers. The AA O103 SL subwoofers are 10-inch. The full range unit remains the same in size. The design of the AA O103 SL, embraces the features of the AA O105 and AA O105 SL series into an even smaller and more accessible system. The results are without compromise, only the maximum intensity of reproduction is slightly reduced, but enough for rooms up to 70 m2. With a choice of special 10-inch subwoofers and special sandwich construction, the weight of a single unit is 13 kg (active version) while maintaining rigidity. The system can be active or passive.

The weight of each unit is very low so the speaker system is flexible to setup, easy to position and adjust. Moderate weight also facilitates internet orders and reduces transportation cost.

Beauty of sound

AA O103 SL is a speaker system without a “box” so the sound is natural, pleasant and free of distortions caused by a normally closed enclosure with bass reflex solution. The system causes minimal sound reflections and resonance in the room because the dipole concept spreads the sound more optimally. The special full range unit with phase linear reproduction offers time coherent. This approach provides very detailed focused 3D reproduction. One big advantage with open baffle design is restriction on the spread of low frequencies outside the listening area. This reduces the volume of music played that neighbors could hear and would be annoying to them.

AA O103 SL includes four speaker units, two full range units and two sub-woofers. The drivers are 5-inch and 10-inch units. The system can be active (with integrated power amplifiers) or passive (external power amplifiers needed).

AA O103 SL is an active system with four power amplifiers providing total 2 x 250W RMS of power. The installed digital signal processor (DSP) offers sound optimization of the system in the room with its 9-pole parametric equalizer. The unit is accompanied by a software package with which we can graphically correct the reproduction response. User can preset three personal equalization (e.g. for quiet and loud listening). The system features XLR and RCA analog inputs, remote control for presets and volume and power on/off. Power on/off can be controlled also with audio input signal.

AA O103 SL P as a passive system provides Bi-Amping (Bi-wiring) and allows regulation of mid and high frequencies with three settings (-2dB, 0dB and + 2dB). The sub-woofers and the full range unit are passively filtered at 150 Hz.


The system appearance can be ordered in various finishes including various colors (matte or piano polished or different veneers, oiled or piano polished).

With its performance, the AA O103 SL is positioned to the very top of the range of all passive/active speaker systems, and with its capabilities and functionality, it will surprise even the most demanding listener.
