Speaking about the SPH-DA100, does anybody know what the bass boost frequency is set at? The manual simply says that it's set at a frequency that should help overcome road noise. That is a very arbitrary statement! 

 

Does anybody here know any details? I'll contact Pioneer and post here if I get an answer. I may have to test it myself with test tones, time permitting...

 

 

This is what Pioneer said:

 

"Thank you for contacting Pioneer Electronics (USA) Inc.

Sorry, I do not know what frequencies the Bass Boost will effect, other than the low frequencies. 

I have ask our engineers to see if they can explain further."

 

I asked them to please ask an engineer or given me a another contact person who may know. That was a week and a half ago. The answer probably isn't coming.
