Ok, well this is the way I am going. I'm getting this head HeadBehringer Ultrabass BX4500H Bass Amp Head. Now I want to know if these cabinets will work with the head and what will my output be for each. This has an *ohm impedance Behringer Ultrabass BA210 500W Bass Cabinet. Now I'm considering one of these which will be my best match. Fender BXR115B Bass 300-watt 8ohm. Carvin 115 JBL Bass Cabinet specs say 600 watts I'm not sure if that's accurate though. Because there is no true model # listedhttps://[Invalid or Expired Link Removed] that is listing. Then there is this one Acoustic B115NEO 1x15 Bass Cabinet listed at 400-watts also 8 ohms. What ones combined with the 2x10 will be best for me. I play Metal in a band with 2 guitar players. Both use Marshall 1/2 stacks. Take in to mind I am a beginner and only have used combos. I had another deal that fell through.
