umm, use search to find the thread, then copy & paste the URL.These speakers are Avant 4A. There is a thread on AK called Avant Loudspeakers...I would attach it but I haven't mastered that just yet..lol
Not Advent

So the brand is Advent and the model is 4a? I searched google and can't find pics like mine or yours.
Judging by the poor fitting woofers and ribbed cones, i'd wager that the woofers in the OP were replaced when the original foams rotted and the clueless took a leap.FWIW the only drivers that look the same between post #1 & #4 are the AD5060 mids. It looks like some similar but different drivers were used, if they are the same speakers (and the cabinets do look alike).
+1. Definitely the wrong woofers.Judging by the poor fitting woofers and ribbed cones, i'd wager that the woofers in the OP were replaced when the original foams rotted and the clueless took a leap.
But what set of woofers are the right woofers? Post 1, or post 4?Judging by the poor fitting woofers and ribbed cones, i'd wager that the woofers in the OP were replaced when the original foams rotted and the clueless took a leap.
The OP's woofers are definitely wrong. @Furburger's woofers could be correct, but based on the screw positions, they've been remounted. Hopefully he'll chime in if he knows.But what set of woofers are the right woofers? Post 1, or post 4?
My speculation would be screws that engage particle board, and whoever did the re-foam chose the course of screws that would tighten evenly by virtue of new/fresh material to engage(new screw holes).The OP's woofers are definitely wrong. @Furburger's woofers could be correct, but based on the screw positions, they've been remounted. Hopefully he'll chime in if he knows.
Sealed designs (as these appear to be) are a lot more accepting of a woofer swap than ported (assuming that the new woofer has similar sensitivity to the old one and it's designed for this sort of enclosure).Here are my screw holes from the OP. I can't tell if they're original or not.
