[QUOTE="CSCStang, post: 8525911, member: 660529"] 4ths aren't simply build and play at all. You build, adjust, rebuild, adjust, etc. I haven't built a ton of them but the ones I've built and the research I've done on the subject in depth conclude that it takes a lot of work. Consensus is you start with 1/2 total cone area and adjust down from there. I've also seen quite a few builds using the 312s in a 2.5:1 ratio to keep the bass punchier as opposed to muddy. Drawback there is some loss in spl and possibly some bandwidth. You just have to build and test. As dbjunior stated it's a good idea to test resonant cabin frequency to match port tuning which will give you more output at peak. Sent from my SCH-I605 using Tapatalk [/QUOTE]
