Hertz CBA 250, automobilinis žemų dažnių garsiakalbis galia: 500 W, Sub Smart Plug, 2 Side 2 Sound technologijos | Nemokamas Pristatymas

"Hertz CBA 250" aktyvaus žemųjų dažnių garsiakalbio dėžė su 10 colių garsiakalbiu turi specialų didelio našumo stiprinimo modulį, kuris patobulina visas pasyvaus garsiakalbio dėžės technologijas.

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 2S²(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. 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. 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. 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.

• Butterworth low-pass filter at 12dB/Oct. with variable cutting frequency (50-200 Hz), Subsonic filter, phase control (0 – 180°), and adjustable bass-boost 0÷6 db @ 45Hz.
• Defeatable filter to use the sub dedicated output of a processor.
• High-level audio input on multi-pin connector for maximum OEM integration and low level on RCA for aftermarket sources.
• ART turn on function (Automatic Remote Turn-On) selectable among: Remote-in, Hi-level, Audio signal.
• Box with ultra-low profile (6.22 in. / 158 mm) in air suspension, designed to take full advantage of the performance of the 10 inch high-impedance driver.
• Down-firing leveling feet with Velcro inserts included for a secure grip with the carpet, ensuring extreme ease of removal.
• Rounded corners allow easy placement in the trunk and act as a reinforcement to reduce enclosure resonances.
• The exclusive design of the cone, dust-cap, and basket geometry to achieve a wide linear excursion (9 mm in one direction), keeping the depth required for the assembly to a minimum.
• HRC AP remote control included.
• A sturdy metal grille is included, for total protection of the subwoofer driver.
