I'm ready to pull the trigger. I WILL buy an extension cabinet to complement my Ashdown 2x10 cab. But, I'm still in doubt about what type of cab to get... another 2x10 or a 1x15?. 
I like bottom-end, so the best choice will be the 1x15, but i've heard that a 1x15 doesn't sound good by itself. It needs to be paired with a 2x10. In the other hand, with another 2x10, I can have a consistent rig for small and big gigs, but I won't get the low-end I want.
I'm talking out of my ass? I'm new to bass rig, so any help is appreciated.
