Hi, show us some pictures if you want us to help you.The Als 40 came many differents woofers, some have Peerless top vent pole and bottom alnico. For the top if you can find imf 8/28 is the perfect replacement for the top one. Ask Falcon acoustics (Jerry) maybe he can help?

Hi, both are paper cone, my top one have a very big magnet like the kef SP1039.But your's original top woofer,maybe it's a peerless with different surround?
