Does your MacBook Pro Retina speakers buzz?

Question

I have the new MacBook Pro Retina, which I absolutely love.  The only issue so far is that the speakers buzz sometimes.  I've tried different equalizer settings, which helps somewhat.  Has anyone else experienced a buzzing or distortion in their audio output?  It almost sounds as though a speaker is blown.

Answer 1

This is what I think the problem with the MB Pro Retina speakers is...
Frequency Response is very good. The speakers sound great with distinct sounds across a wide range of frequencies. But it sounds horrible with low quality TV or movie recordings where a lot of mid range and low frequency sounds hit at the same time in a muddled mess. Volume Handling is simply horrible across the mid and lower frequencies. Many movies will buzz when there is a lot of speech, music and bass going on at the same time unless you lower the volume to 1~2 bars.
This is not a problem with the recording except that the MBP Retina speakers don't like them. Recordings and low quality compression DOES NOT BUZZ, period. They may be low definition, they may sound muddled, they may have cut offs from exceeding the allowed dyanmic range, but they do not buzz. If you play the same movie on external speakers they will not buzz. If I play the same movie on my Dell Adamo it does not buzz. Listening to the same section of the same source on my earphones produce zero buzzing.
I am not sure if the problem is with the speakers themselves of other elements within the MBP Retina vibrating in resonance. But it is definitely annoying. And it sounds like component speakers with improper or missing crossover components allowing frequencies the speakers cannot handle at decent volumes to contaminate the driver or attempting to use mid-bass speakers as sub-woofers -- they actually have the frequency response just grossly insufficient travel of the diaphrams and cannot handle any decent volume.
We may be able to figure out the problematic frequencies and do a narrow cut in volume on them if we have a graphic equalizer. Unfortunately, unlike Realtek and IDT drivers, the Cirrus Logic drivers do not offer an EQ. I am tempted to open the MBP Retina up and try to graft an adhoc crossover onto the four speakers in form of caps and inductors. Given the low wattage of the components the caps and inds will be pretty small. But haven't gotten around to it yet... and part of me don't want to rip the MBP apart.
