Received the drivers yesterday. The Wavecor drivers are very well made and real sleepers IMO. The subwoofer is not in the photo as it's in my buddies shop where I'll build the enclosure. I bought the matching passive radiator for the ScanSpeak 30W/4558T and I'm thinking of using it with the sub in a 57 litre (2 cubic foot) box. Anyone used a passive rad. in their install and if so how did it work out?
