Back when I 1st started playing bass a Fender Bassman or Ampeg fliptop was about all you needed. But then drummers and guitar players got louder and louder and like always the bass got burried. Along came the Kustom 200 with 4x15's. No problem. But then came the Marshall 100watt with 8x12's. good grief how do you keep up with that? Acoustic 360 with 2 cabs or SVT. "YEA BABY!". But things are different now. In a small club setting where all the sound is coming off the stage the biggest thing most people need would be a 2x10, 2x12 or at the most a 4x10 cab. In a large room situation or outside most places use PA support. When working with PA you are better off to keep your stage volume as low as possible and let the PA do the work. Again where do you need big cabinets and big power?
