RHA T20 - Tuning Filters; Reference Filter; Bass Emphasis Filter; Treble Emphasis Filter

Tuning filters
A choice of three
interchangeable lters allows
for personalised ne-tuning of
the sound signature of the T20/
T20i. Each pair of tuning lters
has been carefully designed to
allow a degree of customisation
of the frequency response; this
means the sound signature can
be adjusted for styles of music
that place emphasis on different
parts of the audible spectrum:
Treble Emphasis (copper):
Accentuated higher frequencies
for a more lively and exciting
response in treble reproduction.
Highlights: Jazz, Acapella, Acoustic
Changing tuning
filters
To change lters, remove
the existing lter by turning
it anti-clockwise; line up the
replacement lter with the
opening of the driver housing
and screw in place with a
clockwise motion.
In order to protect the
handmade driver of the T20/
T20i, it is highly recommended
that both housings have tuning
lters inserted at all times.
Reference (silver):
Flat frequency response for
highly detailed and balanced
sound with high levels of
imaging and precise, rened
sound reproduction.
Highlights: All genres
Bass Emphasis (black):
Low end emphasis for more
impactful, direct bass response
while retaining a clear and
detailed sound prole.
Highlights: HipHop, Dubstep, Metal
