So I got a call from the Guitarhangar on Friday -- turns out Eden had shipped a brand-new 15" speaker to replace the one I blew a couple weeks ago.
I picked it up on Saturday, took it home and installed it in the cabinet -- just like new. Broke it in for a few hours, playing through it and then running a line from a boombox at a moderate volume -- Eden recommends this, to seat the voice coil and work off any rough edges.
Used it last night and it sounded great.
Very impressed with the service -- I expected Eden to recone the blown speaker and send it back, which would have been within their rights under the warranty. Sending a new speaker was above and beyond and much appreciated.
Thanks to Rick at Guitarhangar for taking care of the return (and interceding with Eden) and to Eden for great service -- they obviously care about what they make and sell.
