Should double the port area.

Why's that?

You were asking if this would be the most effecient box for your subs. More port=more effeciency. 99% of people will tell you when they added more port, they gained on the meter. That is within reason though. You will have to make the port longer, but will be well worth it. Plus with the port area on this design you will be well over 30/m/sec port velocity between 30-45hz which will cause whistling.

Dont get me wrong it is a very good design for your subs and will have a very good response and gaining response from 31 hz all the way to 215 hz which gives it an overall flat response and an f3 of 29 hz, but by doubling your port area you will get more efficiency throughout the bandwidth seeing as this is not a "peaky" box. Oh and the only problem i seen was the port should be 20 inches long to be tuned to 34 hz not 16in long. That would give you a tuning of 38 and f3 of 33.
