[QUOTE="JLJunkieMX107, post: 8652114, member: 577425"] Designing a passive radiator setup is very similar to a ported design. Slapping a random passive radiator in the other speaker cutout is going to sound like doo-doo. There are actual calculations needed to determine what size passive radiator you need based on the driver, enclosure, and desired tuning. I've forgotten more than I remember on designing these but I want to say the displacement of the passive radiator needs to be at least 1.5 times that of the driver (I am sure you can find a write up on this online somewhere). If you want to get a good idea of how it may sound, just unhook one sub and run it with both installed.
