I'm starting my first system with 4 of the rl-i8's and need a lil help on my box. it's not gonna be just one big box but 4 seperate ported boxes. each one will be about (acording to the program im using) 10" wide, 15" tall, and 9" deep. im having problems with the port though. the program said it should be 1/2" by 2" by 2" deep for a 35 hz. this sounds way small to me. is it? and does this idea seem good or is it too "over the top."
