I'm working on plans for a pair of 112 cabinets using Dayton PA310-8 12" drivers. They suggest a cabinet tuning frequency (F3) of 73 Hz. Reading other discussions on TB, I'm guessing that's too high for a bass rig. But I'm too ignorant about the nuances of this design parameter. I don't want to build cabinets that will kill drivers. I do want to get close to optimizing for a bass guitar. Advice will be appreciated. Thanks.
