2 6inch aeros would be better.

This is the difference between actual response on top and win isd on the bottom. The reading on top came from an excel chart I made from readings taken at just over 60% volume playing test tones from 20-65hz with a 10-15sec average spl reading. The box is tuned at 31.4hz. Note how the peaks are drastically different.
