choosinG a Location
The location of the subwoofer should be 
based on three considerations: sound 
coverage, ease of installation, and the 
ease of running cable to the installation 
location. The large 10” woofer cone will 
provide impressive bass performance for 
a large area when properly placed.
The subwoofer requires a hole with a 
width of approximately 14” (36 cm) and a 
length of approximately 30” (76 cm). The 
depth should be between 16 - 18” (40 – 
45 cm). Additionally, burial rated speaker 
cable must be run from your subwoofer amplier to the proposed subwoofer 
location. Make certain that there are no obstructions in the planned location 
or along the proposed wiring location before proceeding. Many states and 
municipalities have specic notication requirements before digging. Make sure 
to check with your local building authorities as required prior to digging.
Keep in mind when choosing a location that low frequency sounds will permeate 
the entire area which means that the subwoofer does not need to be “aimed” or 
pointed in any particular direction.
The subwoofer is made of heavy duty uPVC, designed for many years of 
rugged outdoor use and will withstand occasional hits from common handheld 
landscape tools, but can be damaged by lawn mowers or other motorized 
equipment. Placing the subwoofer where it is not likely to be struck by such 
equipment will help ensure years of listening enjoyment. This can be easily done 
by careful placement of landscaping features around the bass port tube. 
Also, please be aware that you can control the bass output by your placement 
location. This is called the boundary effect. You will get more bass response 
by mounting the GSS10 near a wall or other at surface. You can increase 
the bass output even more by mounting the GSS10 in a corner location. This 
kind of placement gives the speaker two boundaries, further reinforcing the 
bass sounds. Of course, mounting the subwoofer further away from any other 
boundaries will minimize this effect. Landscaping walls or other structures 
could be utilized for this purpose. A further consideration is that the closer 
the subwoofer is placed to the home, the more chance of unwanted vibration 
entering the home when the subwoofer is played at large volumes.
Choose the location carefully prior to digging any holes or running any wires.
Once the location has been chosen and the hole has been prepared, place the
