Description


The In Phase XTB-88A is a specialized active subwoofer system designed to deliver high-impact bass from a relatively compact boot-mounted enclosure. Unlike the under-seat USW12, the XTB-88A uses a dual 8-inch driver setup powered by a built-in Class AB amplifier, prioritizing sound quality and "thunderous" output over extreme slimness. 


Key Performance Features:

  • Dual 8-Inch Drivers: The twin-driver configuration allows it to move more air than a single-driver unit, resulting in deeper and more resonant bass that "packs a punch" for its size.

  • Class AB Amplification: Rated at 450W, the integrated Class AB amplifier is chosen for its superior sound clarity and dynamic range compared to standard Class D alternatives found in many entry-level active subs.

  • Quick-Release Connections: A standout feature for practicality; it uses quick-release wiring that allows you to easily remove the entire enclosure from the boot if you need extra luggage space.

  • Remote Bass Control: Like the USW12, it includes a wired remote, giving you real-time control over the bass levels from the driver's seat. 


Main Advantages:

  • Installation Versatility: It supports both RCA and high-level inputs, making it compatible with original factory-fitted stereos as well as aftermarket head units.

  • Design Profile: While more powerful than under-seat models, it remains compact—roughly the size of a small desktop computer case—ensuring it doesn't consume your entire boot space.

  • Build Reliability: Reviews of the XTB series generally praise the "proper definition and warmth" of the low end, though it is intended for those wanting "tight bass without shaking the neighbourhood".
