This is a foam port plug for the TuneTot. Occasionally, the combination of TuneTot’s proximity to a shelf or counter top and a rear wall can reinforce the TuneTot's port energy and cause undesirable reinforcement and nonlinearities in this portion of the bandwidth.Wilson Audio's engineers have provided a solution for these types of installations. TuneTot is shipped with two port plugs. These are located in TuneTot’s toolbox. If the bass sounds integrated with the rest of the tonal spectrum, features dynamic authority and transient speed in the mid bass, there is little need to experiment with the port plug. However, if the bass sounds bloated, “woolly” orslow, these are symptoms of an excess of boundary reinforcement. Use the process experiment in the owners manual to safely install the plug.
