INTRODUCTION
Loudspeakers used for guitar amplification do more than simply make the signal
louder. They dramatically shape the signal—significantly attenuating very low
and very high frequencies, while less dramatically affecting other frequencies.
Furthermore, the loudspeaker can interact with the amplifier that drives it, resulting
in a dynamic response.
Unfortunately, guitar loudspeakers can be highly directional and dependent on
positioning. Where the listener stands (or places a mic) in front of a guitar cabinet
can drastically affect the sound. Placing the cabinet too close to a wall, tilting or
raising it off the floor will also have a dramatic effect.
The loudspeakers themselves—especially those used for guitar amplification—can
have serious deficiencies in their response. These speakers are chosen primarily
for their ability to shape the sound at the extents of the response curve, as well
as for high sound output (sensitivity). Response smoothness is sacrificed, which is
generally required for
high-fidelity
sound.
IRs (impulse responses) of guitar speakers are digital samples of the loudspeaker’s
response and are therefore susceptible to these same deficiencies. To make
matters worse, they are usually sampled at specific point-positions rather than
averaged over an area or volume, which results in an inaccurate representation of
the apparent response.
