Adding a subwoofer to your speaker system expands the bandwidth of the bass range. However, if the subwooferâs reproduction bandwidth or sound output level is improperly adjusted, the overall performance may decrease, as shown in the graphs below. When the subwooferâs reproduction bandwidth is correct
Crossover frequency and output level â¢ Adjust the SL-107 output level and crossover frequency to suit your listening room and connected speakers. â¢ When the unit is connected to an ampliï¬er via the SPEAKER LEVEL INPUT terminals, setting the OUTPUT LEVEL knob near the center position will create a well-balanced sound level on most speakers. â¢ Be aware that you might set the subwoofer to a high output level because superbass-range sound is less audible than other sound ranges. To obtain well-balanced frequency characteristics, set the output level to a slightly lower level than seems optimal. (This will also prevent the input of signals that are too strong.) Note: Be careful not to allow the input of excessive power. Input levels that greatly exceed normal situations can damage the SL-107. Also note that switching operations at the ampliï¬er may generate excessive noise that may result in damage. When using switches at the ampliï¬er, ï¬rst lower the volume to prevent accidental damage.
When the subwooferâs output level is incorrect
Output level is too high
Output level is too low
The placement of the SL-107 can greatly affect the sound that is produced. In general, a good bass sound can be obtained by installing the subwoofer in a front corner, or at one-third the width of the wall, as shown.
