    Has anyone attempted to build an Ultimax 18 with passive radiators instead of ports?

    I currently have an Ultimax 18 in a 12 cubic foot box. It sure would be nice to cut the enclosure size in half, if possible, and get the same level of performance. Would that be possible with passive radiators?

    The biggest issue with doing this would be expense. You will probably need 2-3 passive radiators, I have no issues helping you out here, but just keep in mind that it might cost mroe in passive radiators than it did to buy one ultimax 18″. Is that something you can handle?
