I just placed an order for a Powerhouse 4x10 (8 ohms) cab to use with my BB750. I want another cab to run things at 4 ohms and for a little more power (would like more than 280 watts, which is what the BB pumps at 8 ohms). I'm into playing stuff like Tool and Alter Bridge. I play a 5 string bass (MM Stingray 5). I can't decide between a 1x15 cab, 4x10, or 2x12. What would you recommend me that would suit my taste?
