Abstract
An improved loudspeaker system includes an asymmetrical array of dissimilar drivers, namely a first driver and a second complementary driver configured in an array and driven in parallel so that the measured on-axis frequency response and the output power (SPL) is improved as compared to a symmetrical array (with similar or matched midrange or mid-bass drivers), while retaining a flat tonal balance. This speaker system and method for voicing was discovered to provide lower distortion, improved frequency response and greater clarity as compared to the prior art or traditional (e.g., MTM) loudspeaker configurations.
