The Prima APBX 8 AS and APBX 10 AS active subwoofers, with 8 and 10-inch drivers respectively, feature a dedicated high performance amplification module which enhances all the Audison Prima passive box technologies, such as the 2S² (2 Sides / 2 Sounds) design, the Plug & Play terminal block and ultracompact size.
The amplification module, with power outputs of 400W RMS (APBX 10 AS) and 250W (APBX 8 AS) is developed with he-li technology (high efficiency / low impedance), which thanks to the absence of the DC-DC voltage booster reaches the impressive 90% efficiency level, very close to the theoretical limit of the D-Class.
The controls section is complete and provides an optimal regulation of the low frequency emission in the car cabin. The high-level speaker-in input on multi-pole connector eases the integration with OEM audio systems while the low-level input on RCA is dedicated to the connection with after market sources.
The SSP (Sub Smart Plug) terminal block is provided with a single Plug&Play connector to be able to disconnect the box easily and safely.
