Do these woofers look right on these Dunlavys IVA's?

Yep, look fine.  Fritz uses a current version of them.

The random, non factory look of them actually contributes to reducing resonance modes that occur in the cone itself.

ok guys thanks so much

Yes they look correct, I had a pair back in the late 90,s.

Dunlavy on the model  4s had 3 different versions. The big changes were changing the woofers from Morel to Seas to Scanspeak.  The Scanspeak required changes to the crossover and probably to the damping to maintain the Q that John preferred.  Along the way Dunlavy sent me 2 new sets of midranges that looked identical but sounded slightly better to my ear.

Correction..the woofers were Morel, Vifa and finally Scanspeak..Tom
