I'm looking for an inexpensive empty 410 cabinet for some Eden 10's. I can't locate any specs on the speakers. Through some light detective work on the Eden site, I found that the smallest 410 cab that Eden makes is about 6.15 cu.ft. inside and has a bottom slot port. The closest cab I've found is going to clock in at 5.32 cu.ft. and also has a bottom slot port. How much will be missing without that .83 cu.ft?
