BL SPL Enclosure design

[Bonez 0]

I'm looking for specs pertaining to a STRICTLY SPL setup using two BL 18's. What should the port be tuned to? How much airpsace do you recommend if I'm using a single chamber and acoustic coupling?

Can't tell you for sure. . .too many variables.

Have to build, test, modify (or rebuild), test, modify, test, etc. . .

Someone might have a good starting point for you if you post up what vehicle, what type of enclosure you have in mind (wall, box, bandpass, etc.), how much power you will have, what type of competition (bass race, outlaw SPL, legal SPL, etc.).
