Choosing the right location for your Trunami subwoofer can sometimes be daunting. Not only are you limited by the
available wall space in the room, but because it mounts directly into the wall cavity your Trunami cannot easily be
moved after it has been installed.
The most efficient transmission of bass frequencies occurs when the subwoofer is located close to a wall or in a
corner. This is good news because it is hard to get much closer to a wall than flush with it. Unfortunately, depending
on the size or shape of the room, having the subwoofer flush with the wall can sometimes create “boomy” or over-
powering bass. Often this can be overcome by adjusting the frequency and phase settings at the amplifier.
Because the Trunami has a sealed enclosure it is possible to test for bass quality in your room by placing it against
the wall at the various possible mounting locations and listening to it. This will give you a good approximation of the
amount and sound of the bass you will get before you commit to a mounting location. For this to work the room must
already have sheetrock, and will give the best results if the room is complete, including all carpet, furniture and
window treatments.
For smoother bass response or even more total bass output in the listening area, it is possible to install more than
one Trunami in a room. When installing two Trunami’s in a room the recommended mounting configurations are:
• Locate one subwoofer in the front center wall of the room and the other in the rear center wall.
• Locate the subwoofers in opposite side walls of the room, facing each other.
• Locate both subwoofers in the same wall, with each subwoofer mounted at approximately the 1/3 and 2/3 positions
from the ends wall.
Prior to Installation:
The Trunami in-wall subwoofer is designed for new construction and retrofit installations. It is designed to be installed
in between two 2x4’s mounted on 16” centers. If 24” centers are used, add a 2x4 at the correct spacing to make a
16” center wall. The Trunami requires a stud bay opening 14.3” to 15.0” wide by at least 17.5” long. It is possible to
install the Trunami horizontally if the wall has been framed with the correct size opening.
Make sure that no high voltage electrical wire and/or plumbing exists in the wall cavity where the Trunami will be
installed. If so it will be necessary to have a licensed professional re-route the wiring or plumbing either above or
below where the Trunami will be installed. There is not enough room in a standard 2x4 wall cavity to run the plumbing
or wiring behind the Trunami. Also, make sure all plumbing and wiring located in the same wall (not just the same wall
stud bay) as the subwoofer are secured to prevent a buzz or rattle from vibration.
The Trunami subwoofer has an internally braced, sealed cabinet that will prevent MOST of the low bass frequencies
from entering adjacent rooms, but as with all good high-powered subwoofers there will be some sound transmitted
rearward through the wall.
