A subordinate sound chest is a hollow tube and is in different size sequentially such that the main sound case and all other subordinate sound chests can be housed within the largest subordinate sound chest to facilitate moving or storage. When in use the main sound case is disposed on top of a small subordinate sound chest which in turn is disposed on top of a larger subordinate sound chest to form a pagoda like sound case assembly, Thus to enhance low frequency resounding quality. The main sound case and each subordinate sound chest have an opening formed on the bottom wall, have a connection recess formed on the top of a side wall and have a protrudent flange formed outwardly at each side of the bottom wall.
