Where to find OEM Dali Epicon woofer?

Call first and talk to Bill, then send your woofer to Millersound Speaker service for expert repair.  Search A'gon for excellent reviews.

Millersound Speaker Refoaming, Speaker Reconing and Repair Services

Listen, not calling Millersound is a really big mistake.  He lists Dali as a brand he services.

His only business is speaker repair.  If he takes it on, your speaker will sound and look as new, or he won’t repair it.

Again, do a search on Millersound here on A’gon.
