$3,264.00
Wharfedale Pro WLA-218BA-BK is a dual 18-inch active subwoofer designed to deliver high-output low-frequency reinforcement for WLA-210A active line array systems. With 2000W continuous Class D amplification, DSP-based processing, 8 FIR presets, and rugged birch plywood construction, it provides deep bass impact for touring, production, and fixed installation applications.
The Wharfedale Pro WLA-218BA-BK is built to provide the low-frequency foundation for high-output WLA-210A system designs. Its bass-reflex enclosure uses two custom 18-inch Wharfedale Pro ferrite LF drivers with aluminum frames and 4-inch voice coils, producing deep, authoritative bass with strong headroom and controlled response.
Internal Class D amplification delivers 2000W continuous power and 4000W peak power, giving the subwoofer the output needed for demanding live sound, DJ, touring, venue, and installation applications. With a maximum SPL of 148dB at 1 meter in half space, the WLA-218BA-BK is designed for large-scale systems that require substantial low-frequency impact.
Onboard DSP provides 8 FIR presets, allowing fast access to tunings for different system configurations. Preset-dependent crossover operation supports integration with WLA-210A array elements, helping system designers and engineers achieve consistent bass performance across ground-stacked and mixed deployments.
The enclosure is constructed from birch plywood and finished in black Tough-Tone for durability in professional environments. A steel grille protects the drivers, while four handles help with transport, positioning, and production use where rugged handling is required.
