Re: AAAHHHH!!!! [15's in a roc?]



  I am always amazed that so mouch is made of high-power car stereos ...

  My good old speaker design books tell me the lower the bass, the
greater the wavelenght of that bass. The lowest frequency you can
reproduce without distortion is the longest dimension of the room where
you reproduce that sound. Given the dimensions of the Roc, that would be
around 160 Hz.

  There are other considerations too: speaker placement, quality of the
amplifier, body panel vibrations, all that made me spend my hi-fi
dollars in a home stereo instead.

  But I guess feeling all that gut wrenching bass rumbling all around is
the real satisfaction :-)
