ported box size for 2 Boston g2 15"s

[jstaguy24 10+ year member]

I have 2 Boston g2 15's. Right now they are in a prefab box. 2 cu each sub. it sounds pretty good and gets loud. seems a bit boomy at certain frequencies though. seems like certain lower frequencies are twice as loud as others. I am wanting to build a ported box, probably tuned pretty low. more into sql then spl. anyone have any info of what would be a good size and tuning frequency? it's in a suburban so space isn't much of a problem. i'm thinking around 8 cubic feet at 28 hz or so? anyone familiar with these subs?

I put 2 in 7 cubic feet tuned to 32 and it was very nice. Ran about 400 watts to each and they were golden.

just put together one box today. wanted to see if one sub would be adequate. it's about 4.75 cubic feet, tuned at 27 hz. it sounds so much better then the 2 sealed. almost as loud as well. now I'm debating staying with 1- 15. which will mean selling the g2's so I can get a 2 ohm load to my amp.
