The Quartorigo Opus Sub is the ultimate expression of the Opus series philosophy in the lowest frequencies. Opus Sub is designed as an extremely precise tool intended to perfectly complement a reference loudspeaker system. Its role is not to dominate, but to create an absolutely solid, deep and natural foundation for the music, upon which the entire system can build without any compromises.

At the heart of the subwoofer is a 10" driver with a paper cone in a silver finish, visually and technically matching the other components of the Opus series. Paper remains the number one choice in this category thanks to its low weight, natural internal damping and ability to convey bass information with exceptional clarity and structure. The result is a precisely defined fundamental with clearly readable rhythm and dynamics. The voice coil measures 75 mm in diameter and is engineered for high thermal and mechanical stress. The nominal power of 250 W RMS is, in line with Quartorigo’s philosophy, stated as a realistic and long-term sustainable value, not a marketing maximum. The subwoofer’s construction, however, allows seamless cooperation with amplifiers up to 800 W RMS, providing huge power reserves, composure, control and dynamic certainty even in the most demanding passages.

The driver basket is machined from a single massive block of material. This approach ensures absolute structural rigidity and zero assembly tolerances, eliminating any unwanted mechanical play. The result is perfectly precise cone guidance and complete stability even at extreme excursions, without performance degradation or change in sound character. The use of a neodymium magnet is unusual for a subwoofer, but at Quartorigo it becomes one of the key design elements. Neodymium offers an extremely strong magnetic field in minimal dimensions, enabling high sensitivity of 92 dB, fast response and exceptional cone control. At the same time it significantly reduces space requirements, allowing the Opus Sub to be integrated into compact enclosures and demanding automotive installations without performance compromises. Precision-machined cooling channels are placed between the magnet system and the spider, strategically designed to maximize airflow. This solution greatly improves thermal management of the voice coil, reduces compression under long-term load and preserves consistent acoustic properties even at high volumes. The subwoofer therefore operates with complete composure and control even in situations where conventional designs reach their limits.

Like the other components of the Opus series, the subwoofer is equipped with characteristic connection terminals inspired by the shape of a metronome. These connectors are CNC-machined from solid brass and finished with gold plating. This is not merely a design detail, but a functional element ensuring perfect electrical contact and long-term connection stability. Every detail here serves both technical and aesthetic purposes. The Quartorigo Opus Sub is optimized for a sealed enclosure of approximately 17 l, which enables exceptionally fast response, precise control and perfect integration with the rest of the system. The result is bass that doesn’t sound detached, but becomes a natural part of the musical scene – deep, authoritative and at the same time incredibly readable.

Opus Sub is not a subwoofer for everyone. It is intended for listeners who seek absolute quality, technical perfection and emotional depth without compromises. In the context of the global high-end market it ranks among the most advanced and exclusive subwoofers of today – a true masterpiece for music lovers.
