It's time for me to upgrade my cabinets. Dealing with local craigslist that has a cab and a friend that is selling one, I have two options. As for sound, I can use my ears and decide, I just need help with volume. I have an Ampeg SVT Classic head. P and Jazz basses. Option 1: SVT 810 cabinet. A newer model one, I think made in Vietnam. Option 2: Schroeder 1215L This model below an Orange OBC 410. I know people advise against mixing cabs, but the friend who's selling it is an electrical engineer, and has worked for him for years, I trust him. He also refinished the cabs so they look good together. The Ampeg might have more speaker area, but which rig should give me the loudest, mix cutting results? I'm competing with two Mesa Half Stacks and a loud drummer. I want more than I need as opposed to not having enough.
