This came loaded as a replacement driver in my Trace 1153 1x15 cab. I thought it sounded great but I went on a mission to source an original or near original spec driver...which so far has been fruitless. Even a Trace branded Celestion I found that presumably should have been close to original didn't sound as good as this Beyma.
Since I'm not going to have an original driver in the cab, I have decided to go with an Eminence neo replacement so I have no use for this. US Speaker.com
currently lists this particular driver for $199.95 plus shipping and tax if applicable.
I don't know if anyone here would be interested but you could take this one of my hands for
$110 $100 $90 $75
or best reasonable offer
