Dedicated High-performance Amplification Module

Hertz CBA 250 active subwoofer box, with the 10-inch driver, features a dedicated high-performance amplification module that enhances all the passive box technologies, such as the 2S(2 Sides / 2 Sounds) design, the Plug & Play terminal block and ultra-compact size. The SSP (Sub Smart Plug) terminal block is provided with a single Plug & Play connector to be able to disconnect the box easily and safely.

Very Close to the Theoretical Limit of the D-class

The amplification module, with power outputs of 250W RMS, is developed with he-li technology (high efficiency / low impedance), which thanks to the absence of the DC-DC voltage booster reach the impressive 90% efficiency level, very close to the theoretical limit of the D-Class. The Butterworth low pass filter at 12dB/Oct.

Adjustable Bass-boost Control

with variable cut-off frequency (50-200 Hz) can be bypassed, when used with an external processor with pre-out output dedicated to the sub. The adjustable bass-boost control (0 6 dB) at 45 Hz allows the user to emphasize the response on the lower side of the spectrum and the Phase control (0 – 180) completes the equipment.

High-level Speaker-in Input

The high-level speaker-in input on the multi-pole connector eases the integration with OEM audio systems while the low-level input on RCA is dedicated to the connection with after-market sources.

High Efficiency Low Impedance

Integrated 500 W peak/250 W RMS @ 0.4 D-Class amplifier featuring he-li technology (high efficiency / low impedance) without switching power supply, for a performance next to ideal.

Sub Smart Plug

The SSP (Sub Smart Plug) terminal block is provided with a Plug&Play connector to be able to disconnect the box easily and safely.

2 Side 2 Sound

Two sides, two sound design provides the ability to select between Down-Firing positioning to increase the low-frequency extension and Up-Firing installation to obtain more punch and definition.
