1. KS28 is a dual 18-inch subwoofer is a reference subwoofer design to expand the frequency response of large systems.

2. The KS28 features two high-offset, 18-inch direct radiation sensors mounted on the bass reflection tuning housing. The l-shaped vent reduces turbulence and improves low-frequency efficiency.

3. The working frequency of KS28 is 25 Hz. Offset capability transducers, combined with vents help deliver high sound pressure levels and low distortion.

4. KS28 can provide standard or cardiac directivity, by combining physical deployment and appropriate presets.

5.KS28 is the first to fully utilize the power supply of l-acoustic enclosure to amplify the controller. Ensure advan-ced crossover function, linearization and drive protection sensors. Its on-board library provides standard and cardiac presets, each with two low-pass filters to accommodate a-tested various coupling conditions and low frequency profile requirements.
