L7's and CVR's both work sealed, but yes, much better in ported.
Sorry. Couldn't resist. 300 is a decent budget. Especially if you already have an amp. I'm not going to hug the nuts of any particular company but do some research on here and other places. Kicker is expensive for what you get and neither the L7 or the CVR's are designed for sealed. They do well in large ported. Don't make any hasty decisions....
