Positioning the DOUBLE FOUR for Best Sound
Often, playing in different venues will cause your bass to sound different. This is partially due to the acoustics of the hall influencing the low frequency waves that are coming from your speaker. Bass waves are large and room dimensions heavily influence them when the walls reflect the sound waves, causing them to collide by adding together or canceling each other out. This causes some fundamental notes (the ones you feel more than hear) to ring out louder than others and some notes not to be heard at all.
Here is an indication of where fundamental bass frequencies are, showing open string’s approximate frequencies and acoustic wavelength:
B string E string A string D string G string C string
31Hz 36feet 41Hz 27feet 55Hz 20feet 73Hz 15feet 98Hz 11feet 130Hz 9 feet
This may give you some indication of the offending notes (frequencies) that may be booming or resonating louder or quieter than others. For example if your speakers are five feet from a wall, the open A string may sound weak. That could be because the path length of the reflected sound off the wall from your speaker is exactly corresponding to half a wavelength on the open A string causing at that particular note to cancel out.
Where you position the DOUBLE FOUR will ultimately affect your low frequency limit. For best results keep the DOUBLE FOUR on the floor. Placing it on objects off the floor will cause it to sound thin and lack bass punch. Placing the DOUBLE FOUR with the
back close to a wall will help reinforce the lower notes. Placing it in a room corner will

further enhance the low notes.
Room size makes a large difference in how deep the bass will sound. The further the distance to the listener the less the bass will be. This is due to the physics of acoustics not the unit itself.
