Audioguru1,
Take a look at photos of the Wharfedales and the Quads. They are definately not the same speaker. They may have similarities, and who knows, they may be built in the same factory, but they are not the same. The driver flanges are not shaped the same, so I suspect they are different drivers. Also, the Quads have twin ports on the rear and the Wharfedales have a single port on the front.
