ALV Series Subwoofer Motor 110oz

ALV Series Subwoofer Motor 110oz

The ALV Series 110oz subwoofer motor has become a popular foundation for building high-performance 8″ subwoofers. Its strength-to-size ratio delivers excellent magnetic control without the excess mass of larger motors. Because of this balance, builders achieve strong output, clean excursion, and predictable behavior in compact enclosures. As a result, this motor has earned a strong reputation among designers focused on maximizing performance from smaller subwoofer platforms.

While it is most commonly used in 8″ applications, the ALV 110oz motor also works well in properly designed 10″ and select 12″ builds when paired with the correct voice coil, suspension, and enclosure. This flexibility allows builders to adapt the motor to different size drivers based on power goals and available space.

Because of this balance, the ALV 110oz motor performs exceptionally well in applications where space is limited but performance still matters. As a result, it sees widespread use in daily-driven systems, compact high-output builds, and custom OEM-style subwoofer projects. Depending on the selected suspension, enclosure, and coil configuration, builders can tune this motor toward sound quality, daily use, or higher-output applications without overdriving the suspension.

Optimized for 4-Layer Copper Voice Coils

The ALV Series 110oz motor pairs exceptionally well with 2″ diameter, 4-layer copper voice coils using a winding height of approximately 1.4″ to 1.75″. This range provides an ideal balance between control, power handling, and efficiency. The copper mass and winding height work in harmony with the motor’s magnetic structure, resulting in improved BL stability, stronger cone control, and reduced power compression under load.

Controlled Excursion and Reliable Performance

The ALV Series 110oz motor delivers stable flux across the working stroke, helping maintain smooth cone movement and predictable excursion. This stability reduces distortion and improves overall sound quality, especially in smaller subwoofer platforms that demand precise control. Additionally, the compact motor geometry allows designers to optimize suspension and enclosure tuning without unnecessary compromises. Therefore, the motor performs equally well in sealed and vented alignments, depending on the goals of the build.
