Audiocenter - K-LA851B Subwoofer

The Audiocenter K-LA series is primarily used for fixed installation and touring performance systems. After many years' in-depth research, the Audiocenter R&D team has developed the unique PTVTM technology which combines phase and waveguide engineering together seamlessly. This connector, installed between the driver and horn, ensures uniformity and directional accuracy throughout the sound field. With the special horn design, the K-LA-DSP delivers an accurate sound array with extremely low distortion. The K-LA series uses Beyma 1.75" HF drivers with a horn coverage of (H°×V°)100°×20°. The K-LA26 uses Faital PRO 6.5" LF drivers, while the K-LA28 uses Beyma 8" LF drivers. The angle between the modules can be adjusted accurately to ensure Hi-Fi sound quality and a clear sound dynamic. The K-LA series can be either suspended (maximum of 12pcs) or stacked. To ensure that the K-LA series has perfect sound and excellent stability, even at maximum SPL, the range is built with a crossover inside, built-in DSP and Class D amplifiers with switch mode power supplies. Light-weight customized Faital / Beyma ferrite drivers with high SPL and low distortion
Ultra low distortion (H3 distortion average <0.5%)
Advanced cooling system, very low power compression
PWMTM and Class D amplifier circuit
Precisely adjustable angles between the different modules ensure Hi-Fi sound quality and an impressive sound dynamic, whether stacked or suspended.
