Re: El 604
I'm sorry your speaker stopped working. No need to replace the whole tube, we do have replacement woofers. The correct replacement woofer for the EL604 is a WF641.5. The cost is $47.95 plus shipping. Please contact Customer Service at (800) 843-8823 if you would lilke to place an order. If you have any more questions, please don't hesitate to contact us.
