The Turbosound TMS-LOW is a passive 18-inch subwoofer from the TMS Series, engineered for portable applications and built around Turbosound's Turbobass reflex-loaded low-frequency topology. Turbobass is a Turbosound signature — a tuned-port arrangement engineered to deliver extended low-frequency reach with high efficiency, giving rental and small-tour engineers more usable SPL per amplifier watt than a generic ported sub of comparable size.
The 18-inch driver is mounted in a touring-grade braced enclosure with recessed handles for crew transport and integrated mounting hardware so it can be stacked under matching TMS-HIGH mid-high cabinets to form a full-range portable system. The cabinet is passive and driven from a remote amplifier rack running Turbosound's recommended DSP preset for correctly tuned high-pass, low-pass and protection limiting against thermal and excursion abuse.
The TMS-LOW is the dedicated low-frequency partner for the TMS-HIGH and is intended to be deployed in pairs or larger arrays for medium-format portable rigs.
