I recently bought a set of db6500's on ebay. I notice that the diameter of the outer rims on the woofers are 6 1/4". This may require some modification on my part to make them work now as they flop around in the 6 1/2" recess of my enclosure.
Is this normal? Is it like 2x4's not being 2" by 4" anymore? This is the first component set I've used so forgive my ignorance.
