Basically, rare as these speakers are, some left the Wharfedale factory incorrectly wired and using the wrong value for components. If any of you out there use these speakers or know anyone lucky enough to have a pair, please have them contact me and I will provide FOC the correct circuit and circuit values (for those with the 15 Ohm drive units) in order for you to both check and amend circuit values as appropriate.

Issues include L-pad switches incorrectly wired, HF circuit incorrectly wired, wrong values for HF capacitors, wrong LF inductors.

In all the years I've been doing this, I have never come across a more incompetently and badly wired up loudspeaker. Please note, this could well apply to other similar vintage loudspeakers so best check if in doubt.
