For subtle changes in the bass output you can move the product farther from walls or corners that may be emphasizing the low-end with reflected sound. However, if you want to drastically cut back the bass output, newer wave products have a Bass Reduction mode which can be enabled.
This feature was only added recently through software and may not be mentioned in the manual for earlier products (such as the Wave music system III and the original Wave SoundTouch Music System).
You can use the steps below to enable bass reduction mode:
If this feature does not appear, you may need to update the software for your product. The Wave SoundTouch system should be running version 9.x or newer. The Wave Music System III would need version 04.04.01 or newer.
The update would need to come in the form of a disc sent by your local Bose support group. You will need to contact them directly to obtain this. In the USA you can call 800-379-2073 - Hours are M-F 9am to 8pm EST; Saturday 9am-6pm; In other regions you can find contact details by visiting http://global.bose.com and selecting your country from the drop-down menu.
