When you need more low-frequency output and punch than a full-range speaker can deliver on its own, pair it with Truesonic 2 series subwoofers.

The frequency range and crossovers of the Truesonic TS212S, TS215S, and TS218S have been tuned to provide smooth, low-end sound production in the 35Hz-100Hz range (42Hz-100Hz for the TS212S). The extended, powerful bass response will dramatically enhance the overall impact of the music you’re playing.

They also offer XLR+1/4” stereo inputs, balanced XLR outputs, and are housed in compact, internally-braced plywood cabinets with durable metal recessed-handles for easy transport. When you’re ready to extend the frequency range of your live performance reinforcement, Truesonic subwoofers are the effective, economical, and professional choice.

These are class-leading subwoofers and worthy of the Truesonic 2 name.

The Truesonic TS212S, TS215S, and TS218S offer a massive 12”, 15”, or 18” low-frequency driver, respectively. They’re each rated at a whopping 1250 watts and feature a 3” voice coil, which means you’ll always have plenty of low-end volume when you need it most.
