Thanks. I've got a Celestion G12-65 and an Eminence Lil' Texas. The G12-65 is massive, and would add to the weight, if it fits. The Lil' Texas has a neodymium magnet, that would both be lighter and louder. But stock speaker has worked better than I expected, chasing sounds from my SCXD. The more I play around with it, the more I like it.
