Where do you think my DIYSG MBM's are tuned at?

Here is an REW measurement of my 4 DIYSG MBM's. Where do you think they are tuned at? I was thinking about 60hz. Should I get new ports and make them longer? What do you think these guys should play? About 40 to 80hz? I just glued the aeroports together with no tubing... Thanks for your time guys!

Which drivers and what are the dimensions for the box and port(s)? Can't know without the info.

Also, move the mic and retest- you'll probably see very different results.
