ESB Harmony HR10US-A 10" Active Underseat Subwoofer & 5-Channel Amplifier

Transform your factory audio system with a single compact upgrade. The ESB Harmony HR10US-A combines a powerful 10-inch active underseat subwoofer with a built-in 5-channel amplifier, delivering stronger bass, increased speaker power, and enhanced sound quality from one discreet package.

Designed specifically for modern Android-based vehicle audio systems, the HR10US-A provides a simple Plug & Play solution that dramatically improves overall system performance without requiring bulky amplifiers or large subwoofer enclosures.

At its core is a high-performance 10-inch subwoofer powered by a dedicated 200W RMS amplifier channel, delivering deep, controlled bass that adds impact and realism to every genre of music. In addition, four separate amplifier channels provide 35W RMS per channel to power your front and rear speakers, creating a complete audio upgrade from a single compact chassis.

The built-in 4-band equaliser allows precise adjustment of Bass, Mid-Bass, Midrange and Treble frequencies, giving you far greater control over your vehicle's sound than most traditional underseat subwoofers.

Its slim aluminium enclosure is designed to fit neatly beneath most vehicle seats, preserving valuable cabin and cargo space while providing excellent heat dissipation and long-term reliability.
