Significance of the resilience of the Ground Zero Hydrogen GZHW 20XSPL

Power handling is a crucial criterion when choosing a subwoofer. The Hydrogen GZHW 20XSPL from Ground Zero offers an RMS power output of 700 watts and a maximum power handling of 1500 watts. Demand for powerful bass is easily met without overloading the subwoofer. Compared to other 8 subwoofers on the car hi-fi market, this is an impressive value. A higher power handling would potentially enable even higher levels, but could also result in less precision in the bass range. A lower power handling, on the other hand, would limit flexibility when used with loud music. For SPL applications and also in the professional car audio sector, this power handling offers both reliability and performance without compromise.

Impedance options for maximum flexibility in audio design

With impedances of 2x 1 ohm or 2x 2 ohm, the Ground Zero Hydrogen GZHW 20XSPL subwoofer offers maximum flexibility.
