Wharfedale Pro WLA-118SUBA Active Subwoofer 18-inches SKU# WD-WLA-118SUBA

Whaferdale WLA-118SUBA is an 18″ active subwoofer from our WLA-1A System, built to deliver exceptional low-frequency power and precision through integrated Class-D amplification and advanced DSP control.

At its core lies a custom Beyma 18″ driver with a 4.0″ Duo voice coil, engineered to produce deep, controlled bass with outstanding definition and efficiency. Internal DSP makes it effortless to deploy within any WLA-1A array system.

Handling 2200 W continuous (up to 4400 W peak) and delivering a maximum SPL of 136 dB @ 1 m, WLA-118SUBA delivers tight, impactful low-end performance. Designed for flexibility, it can be flown, pole-mounted or ground-stacked alongside WLA-1A full-range elements, forming a powerful and versatile foundation for professional touring or installation setups.

Around the back of WLA-112A and WLA-115A are all the connections and control interfaces needed for a tidy system. Select between 8 DSP presets with FIR filters and control the system remotely with the RS485 network facility.

The 12″ and 15″ elements use coaxial drivers from Beyma – which are manufactured in Europe. This coaxial design gives consistent coverage on both Horizontal and Vertical planes – while competitive traditional two-way line arrays do not have consistent coverage in one axis at least by design. WLA-112A and WLA-115A coaxial design gives consistent coverage and is unique.

EVO-Fold reduces the usual phase issues that traditional 2-way line arrays have due to them having the drive units physically some distance apart in the array. One specially-designed coaxial mid-high frequency driver is loaded to a unique EVO-Fold horn. The EVO-Fold horn combines a unique folded and manifold design. The most advanced FEM technology has been used to create this.

The high-mid energy exits produce a uniphasic sound in the widest range of frequencies. And visually, the detail of the EVO-Fold waveguide is a work of art.

The 21″ subwoofer driver is manufactured by Beyma in Europe. Extreme features… for extreme (and controllable) sub sound pressure levels. Combine the 21″ and the 18″ subs to get extended infrabass from the 21″ and an extreme punch from the 18″. A combination to be experienced!

When interconnecting WLA series active line array elements, quality, certified power cabling should be used. Wharfedale Pro distributors also can supply Neutrik powercon cables as an accessory for sale.

These certified AC interconnecting cables use genuine Neutrik NAC3FCA and NAC3FCB connectors for the ultimate in reliability and safety. 2 meters in length allows for system configuration flexibility while keeping excess cabling to a minimum. A tidy solution for any Wharfedale Pro Active Line Array.

WLA-1A introduces a new Hybrid concept giving variable angles of 0, 5, 10 and 15 degrees.

Easily adjusted using the integral rigging brackets.
