The ideal crossover for satellite speakers can vary depending on the setup and speaker characteristics. A crossover frequency range of 80Hz to 120Hz is often recommended for satellite speakers. This frequency range allows the speakers to handle mid to high frequencies while subwoofers handle lower frequencies. However, the ideal crossover frequency can also depend on speaker size, placement, room size, and acoustics. Therefore, experimentation may be necessary to find the optimal setting. Some subwoofers and receivers have automatic calibration systems that analyze room acoustics and speaker characteristics to determine the best crossover setting.
