The BF181 is a high-performance subwoofer system, designed to deliver tight and accurate bass response with very low distortion.
It features a single 18” long-excursion woofer, with vented double-spider frame and 4” voice-coil, for a stable and prolonged high output.

The direct-radiating woofer is mounted in a vented chamber; exiting into the  X-Venting™ bass reflex port: This centrally located port takes more than 25% of the baffle surface and is designed to maximise the system’s breathing capacity, increasing overall output while minimising port-compression.

The double baffle board and the combination of complex internal panel lay-out with extensive bracing brings a rigid structure with a high enclosure stiffness from a relatively low-weight package. It is finished in Durotect™ scratch-resistant coating and is fitted with 2 handles for easy logistics (road-version).
