Wireless DSP Control

The OSD Black TreVoce series subwoofers come equipped with Digital Sound Processing (DSP) which improves the sound quality by reducing noise, lowering distortion and increasing the dynamic range. You can also control the subwoofer's performance with the free iWoofer app on your smartphone. The app allows you to customize the bass response, control the phase and crossover, and adjust other important settings for an immersive movie and music listening experience. Enjoy effortless control of your subwoofer with the wireless DSP technology in the TreVoce series.

An Energy Efficiency Subwoofer

A subwoofer should blow you away without blowing up your electric bill. The TreVoce 12 powered subwoofer incorporates advanced digital amplifier technology that maximizes performance but, unlike other powered subs that run unnervingly hot, this sub is highly energy-efficient and generates very little heat. In standby mode, it consumes less than 0.5 Watts, making it one of the most energy-efficient subs on the market.

Dialed-in the Performance

The TreVoce 12 includes multiple controls to dial in just the right amount of bass, whether you’re streaming the latest superhero film or chilling out with some smooth jazz on vinyl. Equipped with a mounted volume control, low pass crossover, and phase control, this sub allows you to control how the bass resonates and tailor it to your taste. The TreVoce Series also automatically switches to a power-saving standby mode. Power will turn on when a signal is detected through the input jacks, saving even more energy.

Sonically Sound Inside and Out

Our TreVoce 12 DSP subwoofer 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 architectural settings.
