So I have studied all of the Marty subs and they all seem great. I want more chest slam in my movies and music. So I am going to go with the Classic MBM 18" with the 18" SAF184.03. The reason I am doing this is because I can't figure out how to make my own box which you guys have told me countless times. I just want a flatpack and be done with it. Would this be my best option for more chest slam? Thank you guys for all your help!
