HERTZ speakers go Salzburg

Mille PRO shallow subwoofers have been designed to achieve exceptional performance even when there is very little space available to install the subwoofer box. The subwoofers are optimized to work in ultracompact sealed boxes starting from only 14 Lt (0.49 Cf) for 10′ models (MPS 250) and 22,7 (0.8 Cf) for 12’models (MPS 300). Mille PRO Shallow subwoofers have a depth/performance ratio never achieved
before thanks to the impressive cone excursion capacity which is 20% higher than a traditional design.
500 W continuous power handling is an incredible result for such a compact subwoofer.
To accomplish this ambitious goal, the Hertz R&D has developed the proprietary AIR (Air Intercooling Revolution) technology, optimizing the fluid dynamics of the inner acoustic structure and the magnetic group to minimize the internal compression of air and maximize cooling capacit

Hertz Mille PRO ultra-shallow sealed enclosure
are specifically optimized to deliver all the Hertz MPS
subwoofer performances providing breathtaking low
frequency from a box that is only 160 mm (6.3 in.)
deep for MPBX 250 S2 and 175 mm (6.89) for MPBX
300 S2.

2S² (2 Sides/2 Sounds) design provides the ability to choose between up-firing install to obtain more punch and definition and down-firing mounting, through supplied feet with
Hook-and-loop inserts, to increase the low-frequency extension.

Thanks to SSP (Sub Smart Plug), MPBX feature both Plug-&-Play terminal block and traditional push terminals providing bulletproof connection and quick release.

Ultra-shallow MPS subwoofer driver featuring 500 W
continuous power handling. The panel-to-panel internal
bracing minimize resonances. The 15 mm (0,59 in.) wood
thickness provides an incomparable robustness.

500 W | 0.4 Ohm | Active sealed subwoofer box
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
