AB  - The Thiele-Small method for speaker design considers the linear loudspeaker model driven by voltage sources and operating in a small signal environment. Subsequent studies have been made to introduce into the model some nonlinear characteristics due to the operation with large signals. This paper presents a comparative analysis of the sound pressure level and cone displacement of loudspeaker systems as an infinite baffle, a closed box, a vented box and band-pass enclosure driven by voltage and current sources, under small and large signals. The nonlinearities of the voice-coil, force factor and compliance of the loudspeaker are taken into account.
