[QUOTE="Alex JB, post: 5668898, member: 602795"] I've now gone through a decent ammopunt of my music colection witht heh sealed box and it's just not extending low enough. So I thought I's try the ported box again but this time I added egg crate foam behind the subs and some wadding to try to reduce the wavereflection from the oposite face to the subs and imitate a larger volume. It seems to work well, the large peak in the 40's has gone and the badd is much more of a rumble feel, less boomy. Checked my tuning and I definately calculate it to be 30 - 31Hz Tried 'bass I love you' track and it has no audible peaks through the bass range (36hz, 34hz, 33hz, 31hz, 17hz, and 7hz) that I can tell, other than the 17Hz being sloped off and 7Hz being air movement below audible range of course!.
