A speaker system for reproducing heavy low sounds comprises a tube body having a tubular straight portion and a pair of tubular arms, each of the arms extending substantially in parallel to each other in the forward direction to provide therebetween a wide space opening forward for accommodation, each arm further having sound radiation outlets formed in its forward end portion. A speaker driver is attached to the forward end of one of the arms and communicating with the sound radiation outlets, and a drone cone attached to the forward end of the other of the arms and communicating with the sound radiation outlets.
