Keystone-KST110 is an ultra-slim architectural subwoofer built to deliver powerful low-frequency performance where traditional subwoofers are too deep, too visible or too invasive. Based on Powersoft’s MM-Force technology, it combines compact depth, high output and vibrationless operation in a discreet integration format, including both on-wall and in-wall mounts. Its all-aluminum chassis is engineered for extreme durability, with optional marine-grade resistance for emanding environments. Standard finishes are black and white, with full RAL customization for seamless architectural integration. As an early adopter of MM-Force, K-array applies this breakthrough technology in its own unique way, creating a subwoofer made for discreet, premium and design-sensitive environments. Collapse text

Highlights

Stable by Design. Powerful by Nature.

Inspired by the architectural keystone that supports an entire structure, this innovative subwoofer is designed to become the foundation of discreet low-frequency reproduction. Keystone is the new subwoofer that solves vibration issues in architectural installations thanks to the new Powersoft MMForce® Technology.

MMForce® Technology

MMForce® is built around a moving-magnet architecture, inertially balanced motor design and a square-piston radiating surface to achieve exceptional low-frequency performance from an ultra-shallow enclosure. By maximizing usable radiating area while minimizing vibration transfer to the enclosure and mounting surface, the technology delivers powerful, accurate bass with unprecedented architectural integration flexibility.
