MPBX 300 S2 2 Ohm Sealed Enclosure
MPBX 300 S2 ultra-shallow sealed enclosure is specifically optimized to deliver all the MPS 300 S2 subwoofer performances.
Extreme dynamics, unlimited power handling, realistic sound stage
300 (12) mm (in.) | 1000 W | 2 Ohm
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.

FAQs
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
