ACT Entertainment will present the PK Sound Ts15 compact intelligent subwoofer at the 2026 NAMM Show in Anaheim, California. The Ts15 will be demonstrated in Demo Room 18806.
The Ts15 is the compact low-frequency offering in PK Sound’s Trinity range, which the company describes as the industry’s first series of robotically controlled line source systems. ACT Entertainment said the subwoofer is designed to deliver high-output, low-frequency performance in a low-profile enclosure, with an operating range of 33–130 Hz and peak sound pressure levels of 136.5 dB.
According to ACT Entertainment, the Ts15 was developed to support a wide range of applications with fewer system components. The design combines a compact form factor with high output and tight transient response to support both mobile and installed sound systems.
The Ts15 features a front-loaded, long-excursion 15-inch transducer in a bass reflex design for clean, punchy output. A large vent supports high SPL performance with minimal port distortion. PK Sound’s proprietary VE platform, a single field-replaceable module located on the rear of the cabinet, contains the 2,400-watt Class D amplifier, control electronics and power supply.
Onboard DSP and AVB endpoints are included to simplify setup and system calibration. Connectivity is provided through Neutrik DR Series IP65-rated connectors. The subwoofer also supports PK Sound’s network-based Auto-array functionality via PK .dynamics software, allowing each unit to identify its position within a system and support configurations such as cardioid arrays and arc delays.
Integrated rigging hardware enables ground stacking or single-unit flown configurations using an optional bracket set. An M20 pole mount thread is located on the top of the enclosure, and an optional caster kit is available to support portability.
The Ts15’s low-profile enclosure is designed to fit a wide range of spaces while simplifying transport and deployment for mobile and installed applications. The subwoofer is available through PK Sound’s global distribution network, with ACT Entertainment serving as the exclusive distributor in North America.
