I've got Dayton 18" HO that I've been using at my shop(4000sqft) that is currently sealed and was thinking I could gain a little more output from it if I go with a ported set up. Only problem is I've never really used winisd for anything other than sealed boxes. The box its currently in is about 5cuft but if needed I can always slap something else together... Listen to pretty much everything so I would like it to dig down to at least 25 hz.
Anyone mind modeling a set up for me??
