Sir Streetsounds here, CBe-18 is a longthrow bass bin. Actually its a symmetrical tapped horn with a longer horn path for a longer throw having higher SPL and can reach down to 38hz in singles, I dont have issue with reagards to timings, I used J378 for my midtops also long throw. Kung wala ka speaker management use a long throw midtop.
This cab has a very good directivity with bass purely concentrated at the front.
Actually this is a revision of the standard cyclops designed by Stipe, I just asked him to extend the depth to 700mm and he re-designed and got better result.
