OSD Black Trevoce Triple 12" Subwoofer 

OSD Black BK-TreVoce12 is a dynamic powered subwoofer that offers up to 800 Watts of power and a three-woofer design that dramatically enhances bass in home theaters, media rooms and high-end listening spaces. This robust stand-alone subwoofer has a unique configuration that includes a 12” active woofer and two 12” symmetric built passive woofers. The active subwoofer is self-contained and uses the sub’s amplifier to reproduce sound while the two passive symmetric-built woofers enhance the SPL, all contained within a small enclosure. This delicate balance of internal and external power relieves your main speakers from having to produce low frequency sound, allowing them to focus on mid-range and highs. The result is optimal performance, so you’ll experience movie and music soundtracks with prodigious, and tightly controlled, bass authority.
