I'm going to upgrade to either a 4th or a 6th. I'm aware that a 4th is a ratio between a ported and sealed enclosure and a 6th is two ported enclosures into one that have different frequencies. But, what are the benefits and downfalls of both enclosures? And what are some good subwoofers for both of them? Plan on upgrading my amp later on but no guarantee so kind of flipped on whether to get high power rms subs now or get some like 1500rms and wire to half. All input appreciated!
