I had one in a 2.2ft^3 vented enclosure tuned to 30hz, powered by a bridged NiNe.2 and I loved it. It sounded great for rap and rock music and had the ability to get very loud. The only thing I would watch out for is make sure you have a subsonic filter if you go vented. It seems that a few people have had problems with the cone coming unglued from the spider (my theory - overextention).
