He said don't pair the cylinder and the box... I'm surprised...
I really didn't know they were different... hmm
Did he post any specific reasons for this mike...?
not for this specific question, but his answers to my previous questions lead to this:
1) different output capability due to box having more volume
2) different tuning due to box having more volume
3) the box will have more output below 25hz
(this only applies to the ultra box and cylinder, the other models have very similar performances between cylinder and box)
though Ed said the PB12NSD is the best performing subwoofer out of all the NSD based drivers. (even the supposedly similar PCi 20-39) but he said the differences were slight
