Abstract
This invention provides a speaker port with a flare having an inner wall that minimizes or reduces boundary layer separation. Fluids, such as air and sound waves, flow through the port at a higher velocity when boundary layer separation is minimized or reduced. The inner wall of the port is contoured so that the pressure gradient or change in pressure along the longitudinal axis of the port from its inlet duct to outlet duct is substantially constant.
