hron61 I never inferred that PWK didn't know what he was doing. My question was only in the configuration of the crossover's and if there was a difference between Heresy's with or without speaker grills. There is a sound quality difference without speaker grills.

When PWK engineered, the circuit boards / components, were there changes to the crossovers frequency with cloth grill covers? Somehow my Birch Plywood sound different than the Walnut series.

Not sure if it makes a difference but should each driver be fused, or should it be all in one? Looking like a 2.5 Amp quick blow fuse is correct, maybe.

Were there low numbers of the plywood versions built?

Any thoughts on which Heresy sound best, the plywood or finished? I have the opportunity to purchase the plywood version and I rarely see them.
