Re: GB12's? Eminence?
I have 2 GB12's in my 4x12 slant avatar cab. I use the DSL 50 through this, and it has eminence V12's on the bottom. When i stand in front of both of these speakers I like the GB12's better. They seem more crunchy and clear, whereas the V12 is very bassy, which is why I went with them on the bottom. I personally think they sound great, not sure with a 5150 combo, but they sound great with my Marshall. Hope that helps.
