Audison Prima APBX 8 AS2 - 8-inch Active Enclosed Subwoofer with 250 W RMS

The Audison Prima APBX 8 AS2 is an active 8-inch enclosed subwoofer that delivers powerful deep bass in a compact size. Its integrated He-Li Class D amplifier operates with Dynamic Bass Tracking (DBT) for precise, dynamic bass reproduction – even at high volumes. Thanks to variable filters and well-designed connections, you can easily integrate it into factory and aftermarket systems. The flat, robust enclosure fits easily into the trunk and remains flexible in its orientation.
