Composed of 2×10″ long-throw double-magnetic woofers, the HSP-210BA features a direct structure design to ensure superior sound reproduction and transient response. Used with HCL and HSP Series loudspeakers, it can effectively extend low-frequency performance. The reinforced box structure and optimized wind resistance design allow for exceptionally low resonant frequency. The built-in DSP processor (2-in/4-out) and dual-channel amplifier provide reliable power output for HCL-404 series and HSP series loudspeakers, enabling comprehensive sound reinforcement. Also, the DSP module can set various working modes with one key to switch, allowing for plug and play.
