IVe only built two boxes for a pair of them, first one was 5.2ft @35hz= sh*t my pants at the output quality and loudness, not quite low enough though. Second box was trunkly constricted to 4ft@ 35hz and lost a ton of output and just dissapointed me, so I made it bigger by adding a spare tire well addition, which made it 4.7@33hz. They need at least 2.5ft. ED reccomends tuning to 32 although i think 33 would be low enough.

how did they perform in 4.7cubes?

got mine tuned to 21 and have to say I am impressed with how much output they have all the way up to 70hz (home theater). These things love some room to move no matter what though.
