Had to replace my speakers for the Stallion and they are not easy to find !!! The Sony web site said they are not available anymore ?? I did find them at PacificStereo for $130 with free shipping. Model # is MS-MP1620B. You can find the 1610B for about half price, but it is not the same !!! On the plastic body there is a molded 5"x2 5/8" space so you can't just pick something that looks close to fitting.
