[QUOTE="tinmanchris217, post: 6331284, member: 610505"] Grab yourself a software package to help you test your ideas. SPL boxes inevitably are a compromise between impedance to your amp, cabin gain, and box tuning... So it's hard to help you build an SPL box. Generally though, I've been told to start with a bigger than recommended IV and an easily tunable port. Slowly decrease the IV, until you start to see a drop in output. Then fiddle with the tuning, so that it gets max numbers. Generally this corresponds with your cabin's resonance +- 5 Hz. Take all this advice with a grain of salt though... I can build you an SPL box that's big or small to hit good numbers... it's all about finding a combination that causes the sub's resonance, port resonance, and cabin resonance... while keeping your impedance from hitting a peak. This is all in your box size/port tuning choice... and software is better than trial and error (to a point). [/QUOTE]
