I was just curious if I could run two different 15's...I have an audiobahn Immortal 15 i've loved and have been using for quite awhile...I wanted to try an Alpine Type R 15"...Now I'm curious if I could run both my 15's in a ported box ? Are there any pro's and con's? as i'm sure there are, but what would be the worst outcome? Their both dual 2...Any help appreciated...Thx
