System and method for adjusting the low-frequency response of a crossover that supplies signal to subwoofers in response to main-speaker low-frequency characteristics

Abstract

A system and method for adjusting a subwoofer sonic output in response to known main speaker characteristics in order to produce a desirable blending of sound from the combined subwoofer-main speaker output.

I claim:  
     
         1 . A system for adjusting the frequency response of subwoofer systems comprising: 
 a user interface configured to receive user-adjustable variables indicative of main speaker characteristics; and    a compensation circuit configured to produce a desired low-frequency signal from an input signal in response to the user-adjustable variables.    
     
     
         2 . The system of  claim 1 , wherein the main speaker characteristics comprise low-frequency characteristics of the main speaker.  
     
     
         3 . The system of  1 , wherein the user adjustable variables comprise a low-frequency cutoff frequency.  
     
     
         4 . The system of  1 , wherein the user adjustable variables comprise a low-frequency damping factor.  
     
     
         5 . The system of  1 , wherein the user adjustable variables comprise a speaker sensitivity factor.  
     
     
         6 . The system of  1 , wherein the user adjustable variables comprise an enclosure type.  
     
     
         7 . The system of  1 , wherein the user adjustable variables comprise a gain factor.  
     
     
         8 . A method for adjusting the frequency response of subwoofer systems, comprising the steps of: 
 inputting user adjustable settings indicative of main speaker characteristics; and    producing a desired low-frequency signal in response to the user adjustable settings.    
     
     
         9 . The method of  claim 8 , wherein main speaker characteristics comprise low-frequency characteristics of the main speaker.  
     
     
         10 . The method of  claim 8 , wherein the main speaker characteristics comprise a low-frequency cutoff frequency.  
     
     
         11 . The method of  claim 8 , wherein the main speaker characteristics comprise a low-frequency damping factor.  
     
     
         12 . The method of  claim 8 , wherein the main speaker characteristics comprise a speaker sensitivity factor.  
     
     
         13 . The method of  claim 8 , wherein the main speaker characteristics comprise an enclosure type.  
     
     
         14 . The method of  claim 8 , wherein the main speaker characteristics comprise a gain factor.  
     
     
         15 . A system for adjusting the frequency response of subwoofer systems, comprising: 
 means for inputting a plurality of user adjustable setting indicative of main-speaker characteristics;    means for receiving an input signal; and    means for producing a desired low-frequency signal from the input signal in response to the plurality of user adjustable setting.    
     
     
         16 . The system of  claim 15 , wherein the main speaker characteristics comprise low-frequency characteristics of the main speaker.  
     
     
         17 . The system of  claim 15 , wherein the means for producing the desired low-frequency signal further comprises means for setting a low-frequency cutoff-frequency of the main speaker.  
     
     
         18 . The system of  claim 15 , wherein the means for producing the desired low-frequency signal further comprises means for setting a low-frequency damping factor of the main speaker.  
     
     
         19 . The system of  claim 15 , wherein the means for producing the desired low-frequency signal further comprises means for setting a gain of the main speaker.
