Low frequency equalization for loudspeaker system

Abstract

A method of optimizing the low frequency audio response emanating from a pair of low frequency transducers housed within a cabinet. The low frequency transducers are electrically connected to a power amplifier and source of audio content. The resonant frequency (Fs) and amplitude (Q) are characterized as to the high-pass pole of the low frequency transducers as they are mounted within the cabinet. An equalizer is placed between the amplifier and source of audio content for canceling the complex pole of the low frequency transducers and for establishing a new complex pole at a cut off frequency below which the sound generated by the low frequency transducers will diminish.

What is claimed is: 
     
         1 . A process for designing a speaker system, comprising:
 first optimizing a low frequency transducer with respect to motor strength, low mass, and high suspension stability;   after optimizing the transducer, selecting a speaker box size;   after selecting the speaker box size, choosing a lower frequency limit;   after selecting the speaker box size, installing the driver in the speaker box; and   measuring the Ftc, Qtc of the system.   
     
     
         2 . The process of  claim 1 , further comprising the steps of:
 installing an equalizer in the system; and   setting equalizer settings to optimize the low frequency transducer response.
