I picked cast baskets & dual binding posts on the M60's I just ordered not because it will just be stiffer, but the increased openness of the baskets could help with cooling/air flow even though I don't believe these drivers have a vented pole piece. And looks, lol, even if I won't see them per say. That would be an interesting look with slight adjustments to box volume and running them inverted. =p
