I have a Weber in my Deluxe Reverb, and it sounds great. There are a couple of knocks on Webers, that aren't really, but they always come up.
They take quite a while to break in, and have an odd brittle sound until they do. There are lots of ways to get them broken in, but the easiest is to play a lot. It will sound better with time.
There are a lot of options, enough to be really confusing. Take what ever speaker you want, get the specs and match them as closely as you can with the Weber ones. They allow you to specify just about everyting.
Doping is a treatment that can make or break a speakers sound. Read up on it at the site. I had a speaker without it, different brand, and it would ring like crazy. I put the current speaker I have in, and it was worlds apart for the better. They are other reasons I like the current speaker I have in there, but the doping is responsible for removing that problem.
On the whole, I really like their speakers. But you do have to put in a little effort to get the most out of them.
