摘要： A forward focused bipolar loudspeaker system includes a front-facing driver array and a rear facing driver array with substantially identical front-facing and rear-facing midrange or mid-bass drivers voiced and driven so that the measured SPL curves of each of the arrays, when measured individually, are tonally balanced. The front array and rear array have substantially identical on-axis and off axis frequency response and the rear array's output power (SPL) is reduced by, preferably, about 6 dB with respect to the output power produced by the front-facing array, while retaining a flat tonal balance for both the front and rear speakers, to produce a sound power ratio of about 2:1 as measured by comparing the front and back SPL levels of the speakers. This bipolar speaker system and method for voicing was discovered to provide greater clarity and improved localization while retaining the spacious envelopment of the bipolar sound field.

摘要： 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.
