when i fold horns,i start at the mouth,choose a maximum depth,folding according to that,for midbass cutoffs normally 2folds are enough

Lately i prefer the S style,for woofer access. my 40hz corner horn,its folded more like the labhorn but expands in 1 dimension not 2.

for my jbl horn 3folds are more optimal,no space wasted
