Musway MWF104SQ

The Musway MWF104SQ is an exceptionally slim 25-cm subwoofer designed for high-end car audio installations that require a combination of high sound quality and powerful low-frequency bass with minimal space requirements. With an installation depth of just 74 mm, the driver is ideal for compact enclosures, spare-tire wells, or custom-built side panel solutions.

Despite its compact height, the MWF104SQ features a powerful drive and a large maximum diaphragm stroke. The rigid polypropylene diaphragm is guided by a durable rubber surround, while the solid die-cast aluminum basket ensures stable mounting of the drive system. A 2.1-kg dual-magnet system and the 38.6-mm voice coil form the foundation for controlled and dynamic bass reproduction.

The subwoofer is equipped with a 4-ohm voice coil, making it easy to pair with a wide variety of mono or multichannel power amplifiers. The MWF104SQ is particularly well-suited for sound-quality-oriented systems: Musway recommends sealed enclosures with a volume of just 14 to 25 liters. Alternatively, a 20-liter bass-reflex enclosure is an option if a lower tuning frequency and deeper bass are desired.

The package includes a sturdy protective grille and an aluminum mounting ring, which not only protect the woofer but also allow it to be integrated into custom installations with a clean, sleek look.
