OSD Black TreVoce15EQ DSP is a dynamic powered subwoofer that offers up to 1500 Watts of power and includes a three-woofer design that dramatically enhances bass in home theaters, media rooms and high end listening spaces. A powerful sub with a small footprint, the OSD Black TreVoce15EQ DSP includes a 15” active graphite paper cone woofer and two 15” symmetrically mounted passive glass fiber woofers. The active subwoofer uses the sub’s internal amplifier to reproduce sound while the two passive woofers enhance the SPL, minimize distortion, and improves speed and accuracy. This refined 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, further reducing distortion and gaining SPL. The result is optimal performance, so you’ll experience movie and music soundtracks with thunderous, accurate, bass authority.

Native EQ and App-Controlled DSP Room Connection

The TreVoce15EQ DSP includes an array of controls to dial in just the right bass for what you’re streaming or playing, but what’s truly unique about this sub is the new native EQ and the iWoofer controlled DSP engine that allows the sub to extract the maximum bass extension possible for the full range of musical instruments and special effects whether you’re streaming action and adventure or listening to old vinyl LPs. From your seating position using the Android or Apple App you can make any adjustment needed to get the maximum performance out of your system. It’s also equipped with a rear mounted volume control, low pass crossover, and phase control.

Highly Efficient Design

The OSD Black TreVoce15EQ DSP powered subwoofer incorporates advanced digital amplifier technology that maximizes performance but, unlike other powered subs that run unnervingly hot, the TreVoce15EQ DSP is very efficient and generates very little heat. In standby mode, this powerful sub consumes less than 0.5 Watts, making it one of the most energy efficient subs on the market.

Style and Sonic Purity

The OSD Black TreVoce15EQ DSP includes gold-plated inputs for the highest quality sound transfer and maximum sonic purity. The reinforced enclosure is not a typical fake wood grain but a synthetic leather that blends easily into any décor.
