[QUOTE="hispls, post: 8747547, member: 614752"] You must first calculate the volume of air that port area = to your passive cone area would be then multiply that by the mass of air that would be contained in that port.... or just trial and error. For high power/high excursion you probably want to be more like double the active cone area in passive cone area. Once tuned they theoretically behave just like a port except they're a lot of money and will require a lot of surface area on your box instead of large volume the a big port would eat up for you. Got a pair that someone DIY'd on a forum and I picked up cheap, never had an opportunity to do anything with them and they're up in the garage gathering dust. [/QUOTE]
