PROBLEM TO BE SOLVED: To provide a polymer concrete composition for sound equipment with which a formed body having excellent packing properties and high vibration-proof performance, and exhibiting satisfactory sound effect can be produced. SOLUTION: The polymer concrete composition for sound equipment comprises: (A) a binder comprising a curable resin and a curing agent, and whose viscosity at 25°C is 100 to 700 mPa×s; (B) a particulate filler having a circularity of 0.80 to 1.0 and a mean particle diameter of 5 to 50μm; and (C) aggregate in which the weight fraction of the particles having a particle diameter of≤45μm is≤5%, by specific ratios, respectively.
