I find the best way to find the source of an object is to run this in the terminal:

find ~/code/pure-data/trunk -type f -print0 | xargs -0 grep '"biquad~"'

The class name needs to be declared using gensym("biquad~"), so if you search for the object name with double quotes around it, you'll find that gensym statement:

./pd/src/d_filter.c: sigbiquad_class = class_new(gensym("biquad~"), (t_newmethod)sigbiquad_new,

If you are not part of the solution, you are part of the problem.
