I have a bandpass box, I just bought 2 new subs because the old ones were blown. I though the new subs would fit the same circles as my old subs. Both sets are 12's but my new ones are a little to big. So I used a rasp and made the holes bigger. Now the 2 subs are about a centimeter away from touching. Is this okay? How much space is needed between them? (They have their own air space) They are just close to touching on the top of the box. Thank you
