Box Designer/Builder
The sa8s will normally have a peaked resonance in a standard ported design, unless compression is made larger, which in your case is unlikely. If you control the resonance using a tapered design, either normal or reverse, you should be able to control the peak from those drivers. They are sensitive to specific volume requirements. But if you like the peak resonance, which can also aid in the overall output, then by all means, nothing would be better than a simple reflex with aeroports as requested. It would be recommended to consider other design options as well, than everyone throwing out box volumes from mid air, and actually figuring a response goal ahead of time. If pro-rabbit agrees to let you have him design it, take him up on that rather than trying to gather estimated numbers from many different posts. You will likely get more of what you want that way.
