Direct comparison 3 12s will be louder than 2.just want what's gonna be loudest and sound the best.
Well they are the company that designs and makes the subs so it's hard for me to argue with them. You think they would purposely make their subs sound like @ss? Of course not. Not all subs need massive port area. Actually most subs don't need anywhere near what the people here seem to think. Certainly not 18 per cube. To be honest though the rest of the manual is even weirder.9.4 sq inches of port per cube? That sounds like the big CHUFF
Shame on RE for that.
