Pre owned. In excellent condition. Free from evident signs of wear. Original packaging not included.

The Indiana Line Basso 840 is an active subwoofer designed to deliver deep, powerful, and controlled bass performance in both stereo systems and home theater configurations, combining relatively compact dimensions with remarkably impactful acoustic capabilities. Despite being the most compact model in the Basso range, it is capable of producing highly convincing low-frequency reproduction thanks to its 275 mm woofer and carefully optimized acoustic and electronic design. Indiana Line, the historic Italian brand founded in Turin in 1977, has built its reputation on the rational use of components and engineering solutions aimed at achieving performance levels far beyond what is typically expected within the same price category.

The Basso 840 features a bass reflex configuration with dual rear ports specifically designed to extend low-frequency response while minimizing unwanted turbulence and noise during operation. The reflex tuning is set particularly low, helping to control excessive driver excursion and ensuring cleaner, more controlled bass reproduction even during demanding passages. The woofer is downward-firing, a design solution that enhances low-frequency pressure and improves the distribution of deep bass throughout the listening environment.

The integrated Class AB amplifier delivers up to 125 Watts of maximum power, providing fast and dynamic response with an excellent balance between control, musicality, and driving capability. Frequency response extends from 24 Hz up to 180 Hz, allowing the subwoofer to integrate effectively with a wide range of floorstanding and bookshelf loudspeakers in both music and cinema applications. Its sonic character focuses on delivering full-bodied and deep bass without becoming overly intrusive, maintaining good articulation and precision even during intense low-frequency passages.

Particular attention has also been dedicated to flexibility and ease of integration. The control panel allows adjustment of crossover frequency, gain level, and phase, enabling the user to tailor the subwoofer’s performance according to the characteristics of the audio system and listening room. This level of customization makes it easier to achieve coherent bass integration in a variety of stereo and home theater setups.

From an aesthetic perspective, the Basso 840 features a clean and minimalist design finished in matte black vinyl, allowing it to blend easily into modern interiors without appearing visually intrusive. The solid cabinet construction is carefully engineered to minimize unwanted vibrations and resonances, contributing to cleaner and more controlled sound reproduction. Altogether, its technical and acoustic characteristics make this subwoofer a balanced and versatile solution for listeners seeking deep, dynamic, and well-integrated bass performance for both music listening and cinematic entertainment.
