View Full Version : Thoughts on box design 4cf 30hz

almost 4 cubes tuned to 30.5hz to fit an XFL 15" with 64.2 inches squared of port area


With Front baffle removed


My concern is the air pocket up the top there ontop of the port, should that be a concern or should it be fine?

Another problem is the sub and port will be facing inwards towards the cabin in a hatchback. They will be right behind the back seats. I know rear firing helps with loudness but should I really lose that much?

The whole point of this design is to hide the system so I've made it the same height as the back seats, the angle in the back is to suit the hatchback shape.
