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

If you need a new driver they make their own drivers. You need to buy one from Dali and go through a dealer most likely.

Thanks everyone, I'm in Bay Area, CA, hope to find a local dealer or repair shop.

Hmmm...blown woofers usually still make sound.  Check the connections and if the speaker has multiple binding posts make sure the jumpers are fastened correctly.  Good luck

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.
