Due to the popularity, the performance and high bass response of these speakers we have added additional sizes to the line to provide more options for "HO" scalers and now options for "S" and "O" scalers. Furthermore, to answer the requests of many of our Quantum Aristo and Magnum "G/O" scale users we have added a High Performance FFR (Full Frequency Response) line of larger speakers to our inventory.
