[QUOTE="mat3833, post: 8793861, member: 587645"] You have a pressure wave in front of the cone, and one behind the cone. Sealed enclosures trap the rear wave so you don't get cancelation, that is true. Depending on what the lowest frequency you want to play is, you don't actually even need an "enclosure". You can just use a baffle of a specific diameter, I don't recall the formulas to calculate this unfortunately, to prevent the pressure wave from canceling out in the band you want to play. That's called an "open baffle". Some midrange drivers use this type of design. Matt [/QUOTE]
