i prefer sealed boxes also. if you want missing frequencies but loud on lower ones then go ported but if you listen to a large variety of music then i would recommend sealed. if your not going to compete then i would sacrific loud for nicer sound. i have a car with sealed and one with ported. still prefer the sealed anyday for daily. i like metallica harvester of sorrow, pantera walk etc and like the drum to hit hard and jolt your eyes and make the steering wheel jump. i have tried ported many times and no matter what i always end up doing away with it because i have to limit my music selection which annoys me to no end. ported has its place and so does sealed. you want tight yet still get low go sealed. you want loud lows and a limited selection of music that gets loud then go ported, want to compete in spl go ported.
