Can anyone explain what effect the size of the enclosure has for a subwoofer ? As a bit of a newbie to subs, I'm wondering whether "size really does matter". Can compact subs such as an MJ Acoustic Reference 100 or REL Quake sound as good as a sub with a larger enclosure that uses the same size of driver ? Do sealed enclosures allow smaller sizes than enclosures with a port ? I can understand why a larger driver would make a difference, as it can move more air, but why would a larger enclosure make a difference ? Thanks!
