Hertz - CBA 250 - 25cm subwoofer

CBA 250

250 (10) mm (in.) | 500 W | 0.4 Ohm | Active sealed subwoofer box

The CBA 250 active subwoofer box from Hertz with the 10-inch driver has a specially adapted high-performance amplification module that improves all the technologies of the passive box, such as the 2S² design (2 sides / 2 sounds), the Plug & Play connection block and ultra-compact size.
The SSP (Sub Smart Plug) connection block is equipped with a single Plug & Play connector to disconnect the box easily and safely.
The amplifier module with an output power of 250 W RMS was developed with He-Li technology (high efficiency / low impedance) which, thanks to the absence of the DC-DC voltage amplifier, achieves the impressive efficiency of 90%, which is very close to the theoretical limit of the D-class.
The Butterworth low-pass filter at 12 dB / oct. with variable cutoff frequency (50-200 Hz) can be bypassed when used with an external processor with pre-out output for the sub.
The adjustable bass boost control (0 ÷ 6 dB) at 45 Hz allows the user to emphasize the playback on the lower side of the spectrum and the phase control (0 - 180°) completes the equipment.
The high-level speaker input on the multi-pin connector facilitates integration with OEM audio systems, while the low-level input on the RCA is intended for connection to after-market sources.

• Butterworth low-pass filter at 12 dB/oct. with variable crossover frequency (50-200 Hz), subsonic filter, phase control (0 – 180°) and adjustable bass boost 0÷6 db @ 45Hz.
• Switchable filter to use the sub output of a processor.
• High-level audio input on multi-pin connector for maximum OEM integration and low-level audio input on RCA for aftermarket sources.
• ART (Automatic Remote Turn-On) switch-on function selectable from: Remote-in, Hi-Level, Audio signal.
• Ultra-low profile box (6.22 inches / 158 mm) in air suspension designed to fully exploit the power of the 10-inch driver.
• Downward-facing feet with Velcro inserts for a secure hold on the carpet and extremely easy Remove.
• Rounded corners allow easy placement in the trunk and act as reinforcement to reduce cabinet resonance.
• The exclusive design of the membrane, dust cap and basket geometry to achieve a large linear excursion (9 mm in one direction) and reduce the depth required for mounting to a minimum.
• Includes HRC AP remote control.
• A sturdy metal grille is included to fully protect the subwoofer driver.

High Efficiency - Low Impedance

• Integrated 500 W Peak/250 W RMS @ 0.4 Ω D-Class amplifier with He-Li technology (high efficiency / low impedance) without switching power supply for a near ideal performance.

2 Side 2 Sound

• Two sides, two sound designs offer the option to choose between down-firing positioning to increase low frequency extension and up-firing installation for more punch and definition.

Sub Smart Plug

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