HERTZ MPBX 250 S2

The Hertz MPBX 250 S2 is a high-quality, sealed 25-cm subwoofer designed for demanding car audio applications that require powerful low-frequency bass and a compact footprint. The exceptionally flat enclosure has been specifically tuned to the integrated MPS 250 S2 subwoofer and delivers precise, controlled bass reproduction with high dynamic range. Thanks to its versatile mounting options, the subwoofer can be oriented to radiate sound upward or downward, depending on the desired sound character. The sturdy MDF construction, featuring internal bracing and sound-absorbing material, reduces resonance and ensures clean, powerful bass. The integrated SSP (Sub Smart Plug) connector enables a secure and quick connection and makes installation and removal much easier.
