The active electronic circuit is a complete unit of modular construction, located at the rear of the loudspeaker cabinet where its terminals are exposed. A metal plate carries the input circuit board with the XLR and Cinch inputs, the mains socket, the automatic power-on circuit, the room adjustment controls and the stabilised voltage supply. The second level of circuit boards houses the active crossover unit and all the signal processing circuitry. The three output modules for the bass, mid-range and high-frequency ranges constitute the final level.

The TCI 1 Active loudspeaker incorporates yet another amplifier: a push-pull Class A valve-based output stage.

Zero-loss, active crossover units.

Optimum coupling between the output stages and the loudspeaker drive units, combined with outstanding damping factors, providing optimum control of the travel characteristics of the speaker units.

Frequency response linearisation, expanded bass range and perfectly regulated cone travel (motional feedback).

Compensated timing for each segment of the frequency band, optimum peak handling, perfectly timed reproduction.

No transfer losses induced by loudspeaker cables. Separate power amplifiers for bass, mid-range and high-frequency ranges for improved dynamic response.

Low distortion, extremely low total harmonic distortion (THD).

Option of active compensation to match the listening room and speaker positions.
