[QUOTE="Timber_MG, post: 243734, member: 18"] That'll never even remotely be enough port area for 2 15s With a slot port, I was suggesting a smaller diameter, shorter sonotube within the sonotube to act as a slot all the way round. Transmission line Sono subs use the smaller tube inside, but extend it almost to the other end for a ~4m folded transmission line. I might look at other options in that case to accommodate two woofers. Perhaps move them one way on the end-cap and make a semi half-moon port. The larger the smallest distance between walls in a port the better from an air-flow p.o.v. 500mm sono tube 380mm woofer gives you 120mm space which is a little tight tbh. [/QUOTE]
