ACT Entertainment announced it will present the PK Sound Ts15 intelligent subwoofer at the 2026 NAMM Show, where it will be demonstrated in Demo Room 18806. The Ts15 is the compact low-frequency component of PK Sound’s Trinity range, which the company describes as the industry’s first robotically controlled line source system series.

The Ts15 is designed to provide high-output, low-frequency performance in a low-profile enclosure. According to PK Sound, the subwoofer operates in a frequency range of 33 to 130 Hz and delivers peak sound pressure levels of 136.5 dB, positioning it for a wide range of live sound and installation applications.

PK Sound said the Ts15 was developed to help users cover multiple use cases with fewer individual products. The company said the subwoofer is intended to deliver strong low-frequency impact and tight transient response while maintaining a compact form factor for flexibility in deployment.

The enclosure features a front-loaded, long-excursion 15-inch transducer in a bass reflex design. A large vent is intended to support high SPL output while minimizing port distortion. Amplification and control are handled by PK Sound’s proprietary VE platform, a single field-replaceable module mounted on the rear of the cabinet. The module houses a 2,400-watt Class D amplifier, control electronics and power supply.

Onboard digital signal processing and AVB endpoints are included to support system setup and calibration. Signal routing is handled through Neutrik DR Series IP65-rated connectors, which are designed to provide stability in demanding environments.

The Ts15 supports network-based Auto-Array functionality through PK .dynamics software. According to the company, this allows each subwoofer to recognize its position within a system, simplifying deployment and supporting advanced configurations such as cardioid arrays and arc delays.

Integrated rigging hardware allows the Ts15 to be ground-stacked or flown as a single unit using an optional bracket set. An M20 pole mount is included, and an optional caster kit is available to support portability. The low-profile design is intended to help the subwoofer fit into a wide variety of spaces and pack efficiently for transport.

The PK Sound Ts15 is currently available to order through PK Sound’s global distribution network. ACT Entertainment serves as the exclusive distributor of PK Sound products in North America.
