6 Coverage
Your F81 loudspeaker system has been designed to provide excellent performance without
resorting to complex positional or spacing requirements, but it’s worth spending a couple of
minutes reading through the following sections on horizontal and vertical coverage, placement
and mounting accessories to ensure you get the best performance possible at all times.
6.1 Vertical and horizontal responses
The horizontal and vertical response plots show the on-axis (upper trace) and off-axis (lower trace)
responses.
Your F81 has been
designed to work
well as a stand-
alone system
without off-axis
room colouration.
Its high frequency
response maintains
a useful off-axis
spectral balance.
