Configuring the X300A Wireless is accomplished via a ‘setup wizard’ (for OS and Windows), available for download from KEF.com. KEF says the X300A was designed with the ability to switch between desk, free space and desk/wall modes, to adjust the equalization for location (desk and stand modes are selected via a switch on the rear panel of the master speaker; wall mode is adjusted using a foam plug for the rear reflex port).
