All you would need is a pair of 4" x 10" ports and you'd end up with a tune just under 20hz after accounting for some bracing. 300 watts is to much power, you would be better with a 200 watt amp
If you just want a simple, smaller sealed sub, you should go with an amp that has boost, like this Yung SD300-6
. The box has to be 3ft3 or less in size to handle 300 watts without exceeding xmax. 21"x21"x16" would get you 3.2ft3, allowing bracing and the woofer to drop the volume.
This is a comparison of the ported (green) vs sealed (blue).
could you run #'s for the Dayton PA460-8

i found that at around 169l (~6cu.ft.) tuned to 40Hz it was real flat with a nice steep rolloff around 35Hz(-3db). but i need validation and proper port size if using the flared Dayton ports from post #1, or, proper slot port size (i like look of the round flares better, but either will work for me). no onboard amp for mine.
i am building diy subs for what i call tailgating at the park.
