Audison has capitalised on the success of the APBX-10DS and now supplies a compact closed box with a 10-inch subwoofer equipped with a built-in amplifier of 400 watts RMS. The woofer is the same as the other subwoofers in the excellent series, but with ultra-low impedance coils. Together with the amplifier module with an impedance of 0.16 ohms, this forms the basis for the HE-LI technology (high efficiency low impedance). The result: a deep, tight bass without too much power consumption. The coffin is designed so that the speaker can be installed with the woofer (firing downwards) for a deep bass or with the woofer in front/upwards for a tight bass. Note: Due to the ultra-low impedance, never add another woofer with the built-in HE-Li amplifier. 400 watts RMS / 800 watts peak power, impedance 0.16 ohms, high level input + automatic RCA inputs. Dimensions: 46 x 33.8 x 15.8 cm including HRC-AP bass remote.
