The OSD Audio TreVoce 8 DSP Subwoofer is the perfect balance of power and finesse. This dynamic powered subwoofer is rated up to 300 Watts and includes an internal Digital Signal Processor (DSP) that modifies the audio signal digitally for tighter control on output accuracy. The unique audio architecture of the TreVoce 8 also includes a three-way woofer design with an 8” active graphite paper cone woofer and two 8” passive glass fiber cone radiators. The active subwoofer is self-contained and uses the sub’s amplifier to reproduce sound while the two passive radiators work in conjunction to produce tight and articulate bass. The result is enormously full Low-Frequency Effects (LFEs) that would only be possible with a larger, more expensive ported bass enclosure. This complex balance of components relieves your main speakers from having to produce low-frequency sound, allowing them to focus on mid-range and highs, so you’ll experience movie and music soundtracks with breath-taking authority.
