to experiment with increasing or decreasing the low pass filter control. This control will raise or lower the frequency cutoff point of the woofer.
If you find that the sound is “thin” or lacking in mid bass, and that turning the gain control up to “thicken” the sound creates too much low bass, this is a good indication that you may want to turn the low pass filter up to a higher frequency instead. This will extend the response of the S2/12t into the upper bass regions without affecting the low bass level.
Next, check the S2/12t using more than just a voice. Select some music that you know to have good deep bass, a symphonic piece of music if you can, or use a natural bass instrument for your guide. Try to make it sound real. You may have to return to the vocal track from time to time to make sure you have not gone too far in one direction.
If, at this point, the overall sound seems to be lacking in mid bass, turn the low pass filter to a higher position or, alternately, position the main speakers closer together in order to achieve better mid bass coupling between the main speakers. If the overall sound is too “fat” turn the low pass filter down or adjust the gain. At this point we suggest you use only the low pass filter control until you get to the refinement stage.
Low bass
If you find that there isn’t enough deep bass in the overall sound of the system, your first remedy is the gain control on the S2/12t amplifier. This has several limitations. First, turned up too high, it may result in some distortion on very low frequencies.
Secondly, you may make the mid bass produced by the top of the woofer out of proportion with the mid bass produced by the
A good rule of thumb is to first adjust the gain control of the subwoofer for proper mid bass response rather than low bass. The theory is that if the mid bass response is correct, then the low bass response should be very close to correct.
A good balance between proper low bass extension and a deep and spacious soundstage needs to be established to optimize your new speaker’s performance.
