ESX HZ800A

The ESX HORIZON HZ800A is a compact active subwoofer that delivers powerful bass reinforcement in your vehicle without taking up much installation space. The system combines a 20 cm (8-inch) woofer with a built-in Class A/B amplifier and delivers an output power of 100 watts RMS or 200 watts peak.

Thanks to its slim design, the HZ800A is particularly well-suited for space-saving installation under or behind a vehicle seat. The rugged die-cast aluminum housing also aids in heat dissipation from the built-in amplifier.

For custom sound tuning, an adjustable low-pass filter, a bass boost, and a switchable phase inverter are available. The fixed subsonic filter protects against unwanted low frequencies. The included bass level remote control allows you to conveniently adjust the bass volume from the driver’s seat.

Thanks to its RCA and high-level inputs, the active subwoofer can be paired with both aftermarket radios and many factory-installed audio systems. An automatic power-on function makes it easy to integrate into existing car audio systems.
