I had RE SX 18's in 14cu ft @ 32 hz, and they got LOW.

I would shoot for around 6cu ft per sub tuned to 32-34hz, with a nice fat *** port.

yep, 12ft^3 after displacements and about 150in^2 of port should do well.

you told me "those go well in about 5 cubes i believe" ....I appreciate the help but it was a pretty vague answer...just looking for more input and ideas
