This paper reports details of an investigation conducted on back-end interactions inside a sealed, dual-loudspeaker enclosure. To wit, coupling of five system arrangements are assessed by electrical impedance and free-field onaxis pressure measurements. Measurements are presented with the intent to discuss comparisons and observations on the front mutual impedance and enclosure compliance coupling of the two drivers. Results are in good accordance with expressions of electrical impedance simulated from LTSpice analog circuits models.
