closer together in order to achieve better mid bass coupling between the main speakers. If it sounds too “fat” turn the low pass filter down or adjust the gain. At this point it is suggested to use the low pass filter control until you get to the refinement stage.
Low bass
If you find that there isn’t enough deep bass, your first remedy is the gain control on the woofer amplifier. This has several limitations. First, turned up too high, you may get 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 bottom of end of your main speakers. This would make your system sound “boomy” in the mid bass regions.
A good rule of thumb is to first set the gain control of the subwoofer for proper mid bass rather than low bass. The theory is, if the mid bass is correct, then the low bass should be very close to correct. If the mid bass is proper and the low bass is still not right, you should move your G928 towards a corner for more wall loading. Do this in small increments (a couple of inches at a time). It is easy, and yet unproductive to go too far!
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.
It should be noted that when you originally set up your main loudspeakers, you most likely made placement decisions based on the quality of imaging and proper bass levels. So now, let your new 928 subwoofers take care of the bass, and you can position your main speakers for best imaging and tonal balance.
Fine tuning an audio or video system is an art that will take time and patience. It can be one of the more rewarding learning experiences you will have in the pursuit of music or video and their enjoyment.
One of the best pieces of advice we can offer is that you take advantage of the ear’s ability to identify similarities in sound. This ability is useful in fine tuning your system because if every recording you listen to (or every video you watch) has a similarity of sound (too much or too little of a certain frequency for instance) then you can be fairly certain that you have yet to perfect your setup.
