About: Hertz MPBX 250 S2 10" 500W RMS Shallow-Mount Subwoofer Enclosure Box 

MPBX 250 S2 ultra-shallow sealed enclosure is specifically optimized to deliver all the MPS 250 S2 subwoofer performances. The enclosure structure features incomparable robustness thanks to 15 mm (0.59 in.) wood thickness. Internal sound-absorbing material virtually increases the box's volume and reduces acoustic resonances. Panel-to-panel internal bracing with solid corners minimizes resonances and round corners ease the placement.  2S² (2 Sides/2 Sounds) design provides the ability to choose between Down-Firing mounting, through supplied feet with Hook-and-loop inserts, to increase the low-frequency extension, and Up-Firing installation to obtain more punch and definition. SSP (Sub Smart Plug) features both Plug-&-Play terminal block and traditional push terminals providing bulletproof connection and quick release.
