SERIOUS DRIVERS

∮102.6 diameter voice coil.
Thats OVER 4.0″ but we say 4.0″ because of number rounding
Double-layer spider bonding.
Updated glue is used. This bonding can eliminate brittle cracking and reduces harmonic distortion.
112 g Membrane.
The WLA-218BX driver has a heavier membrane which can withstand more power without breaking.
31 mm voice coil cavity.
A larger internal cavity for the coil windings allows WLA-218BX to have lower response by 5 Hz.
6.2 ohm impedance.
The impedance peak is higher in the Reason-X driver at 35 Hz. This results in superior low end strength.

BIRCH PLYWOOD

WLA-218BX is constructed of 18 mm thick Baltic birch plywood.

Not only does this create a solid and durable cabinet, but it also contributes to the overall sound and character.

WLA-218BX is also covered in our most durable and hard wearing Rhino Rock paint finish. This ensures that it will always look as good as the day you unboxed it.

SOLID AS A ROCK

As with all Wharfedale Pro PA systems, years of expertise is behind a loudspeaker built to last, with thanks to our high standards of quality control.

The WLA-218BX is coated in the highest quality Rhino Rock paint finish – a chip resistant texture with a professional, discrete aesthetic whilst being prepared for the rigours of life on the road.

ROUTED LOGO

WLA-218BX features a routed Wharfedale Pro logo.

It is a logo to be proud of. A logo that lets your audience know that the sound of your even will be of the highest possible quality.

AMPS & DSP

A Versadrive DSP (such as SC-48 FIR) or a DP-N series amplifier with internal FIR filtering is highly recommended to get the most from the system. Phase, EQ and filtering should be applied and this way, the physics of the system can be truly optimised – delivering that sub-bass ……directly into the faces of the audience!

WHEELY PRACTICAL

For easy transportation, WLA-218BX is compatible with Wharfedale Pro optional caster wheels.

INVERTED STACK GRADIENT ARRAY (ISGA)

When deployed in an Inverted Stack Gradient Array (iSGA) configuration, WLA-218BX really moves some air !

A front grille speakON compatible connector means that the Gradient Array can easily be built with other subwoofers.

Working together, the phase will combine resulting in more directional low-end frequencies which focus on the audience, rather than backstage.

Delivery Exclusions

PLEASE NOTE:

Some products are exceptionally large, heavy or bulky and require specialist freight services. This typically includes items such as large PA speakers, dual 15″ speaker cabinets, dual 18″ subwoofers, flight cases and other oversized or very heavy equipment.

We work hard to keep our prices as competitive as possible and, in most cases, delivery is completely covered by our standard shipping rates. However, for certain oversized items being delivered to regional or outlying areas, the actual courier cost can be significantly higher than standard deliveries. This is also owing to factors completely outside of our control (petrol costs and rising costs of delivery by courier partners)

If this applies to your order, we will always contact you before dispatch to discuss the available options. These may include:

Proceeding with a small additional freight contribution.
Collecting the order from one of our suppliers or a nearby courier depot where available.
Cancelling the order for a full refund if a suitable solution cannot be reached.

Please be assured that we only request an additional freight contribution in exceptional circumstances where the courier cost is substantially higher than normal. Our goal is always to deliver your order at the advertised price whenever possible.

If you’re unsure whether an item may be affected, you’re welcome to contact us before placing your order and we’ll gladly provide a delivery estimate.

Thank you for your understanding and ongoing support!
