The B&C Speakers 12HPL76 12" speaker features a cast aluminum basket that is designed to effectively dissipate heat during demanding use at full power, thereby reducing power compression. The driver's powerful neodymium magnet and 3" diameter inside-outside aluminum voice coil provide a good combination of efficiency and power handling. The 12HPL76 is recommended for compact two-way loudspeaker systems in which power is limited to 350 watts RMS or 700 watts continuous program. Also works well as a midrange driver in larger direct radiating or horn-loaded concert PA systems.
