LINE ARRAY SPEAKER WITH FREQUENCY-DEPENDENT ELECTRICAL TAPERING OPTIMIZED FOR MIDRANGE AND HIGH FREQUENCY REPRODUCTION IN THE NEARFIELD

摘要

A speaker system is provided having a line array of drivers wired in parallel and treated with passive or active component systems that serve to electrically taper its effective radiating length with frequency so that it is long/tall at low frequencies and short at higher frequencies, with the effective length of the array determined so as to maintain a listener in the nearfield at typical home and studio listening distances while minimizing the destructive effects of path-length dependent high frequency comb filtering. In alternate embodiments, an array of drivers is provided and wired in series or series-parallel with passive components between the output of one driver and the input of the next. Schemes of active drive and combination schemes of active and passive drive are also contemplated.
