Hi, Im a bass player. I want to build a 15 inch cab that is small and would be good for my Ampeg 1000W 7PRO amp. Is a ported reflex the best for this? I would love to find a cab that gives better performance than that. I would love to have two small cabs at 8 ohm to then use both to get full power at 4 ohm when run together in parallel.
