[QUOTE="Gauntlet, post: 190530, member: 545529"] Well, [URL="http://www.virtual-technologies.com"]http://www.virtual-technologies.com[/URL] does work. They are just ported boxes, nothing special at all. And you should never buy a pre-fab ported box, they should always be made specifically to your subs specs. And for the record, ported boxes will not make the bass more clear. The port will pull air out at the same time the woofer pushes air to reinforce the bass and give around 3 DB gain, but consequently SQ is lost. The port size acts as a high pass filter, to cut off lower frequencies, or the whatever frequencies you dont want to hear, all depending on what the box is tuned to. This is why they have to be built exactly to the subs specs. [URL="http://www.diysubwoofers.org/prt/"]http://www.diysubwoofers.org/prt/[/URL] [/QUOTE]
