Performance of enclosures for low-resonance high-compliance loudspeakers

This paper analyzes the low-frequency behavior of the vented loudspeaker enclosure and the pressure-tight closed box. Inherent interrelationships of the speaker-amplifier system Q, efficiency and response balance are discussed. A method is described for design of small enclosures with very low.resonance high-compliance loudspeakers. The author concludes that the vented enclosure can have greater acoustic output for a given amount of distortion, lower total harmonic, intermodulation, and transient distortion than a completely closed box of similar size.
