K2 is a dual 12-inch three-way line array speaker

1.K2 is a full range component of WST line source, with variable curvature and adjustable horizontal directivity.

2.K2 speaker enclosure is based on 3-way active design. It includes 4 input parts: 2 LF and 1 MF, nominal impedance is 8 ohms, 1 HF. The rated impedance is 16 ohms. It has two 12 "speakers and four 6.5", all directly radiating speakers mounted in a bass reflex enclosure and two 3-inch diaphragms with a single DOSC-coupled compression driver waveguide and adjustable directional fins.

3. The sensor is implemented in a k-shaped configuration. The cabinet is made of processed first-class Baltic birch plywood combined with die-cast aluminum side panels to ensure maximum acoustic and mechanical integrity while minimizing weight. A four-point rigging system is integrated into the cabinet. The KHz enclosure operates in the rated frequency range of 35 Hz to 20 kHz. Its LF resources can be enhanced by a dedicated K1-sb expansion, and its bandwidth can be expanded to 25 Hz with the SB28 subwoofer.

4. On the horizontal plane, the directivity can be adjusted to 300 Hz, with two symmetric settings (70 ° or 110 °) and two asymmetric settings (90 ° is 35 ° / 55 ° or 55 ° / 35 °). The K2 rigging system allows the vertical assembly of shells with various angles between units (up to 10 °), forming a linear array with variable curvature. The combination of coplanar and DOSC waveguides in the high-frequency region ensures perfect acoustic coupling of the elements of the array. It meets the WST (Wavefront Sculpture Technology) standard, so that such an array can be limited to a true line source.

5. Any WST line source provides smooth tonal response and coverage, and there is no secondary split in the entire frequency range. K2 is driven by the D70 controller and quadruple amplified, with factory presets to ensure linearization, protection and optimization of the speaker system.

KS28 dual 18 inch subwoofer line array speaker

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.
