Room Tuning & EQ Settings
MECHANICAL ADJUSTMENT OF THE BOUNDARY FREQUENCY
By using the supplied bass damping plugs in the bass reflex ports, you can alter the in-room
frequency response of your subwoofer particularly allowing you to tune the subwoofer
performance in small rooms or near boundaries and corners.
This gives you the flexibility to alter the sonic signature of your subwoofer and make it
work best within a variety of environments.
The picture below shows three basic settings:
•
PLUGS REMOVED
Removing the reflex port plugs will increase the
efficiency of the subwoofer so that the subwoofer produces higher
sound pressure levels in the 30-80Hz range, than with both ports
plugged. This is great if you have a larger listening room or a layout
that just seems to soak up the bass. In the correct setting with no
plugs in the ports, the subwoofer will provide a “quick”, “rich” and
“punchy” bass character.
•
ONE PLUG INSERTED
Plugging just one port and leaving the other
port open, will provide a middle ground response ideal for medium
sized rooms or to suit your taste.
•
PLUGS INSERTED
With both ports plugged, the air flow through
the vents is resisted thus changing the dynamics of the subwoofers
operation. It will tend to reduce the level of bass but can restore the
response to one having an ideal transient character or speed. This
is particularly relevant if you’re operating the subwoofer in a small
room or against a boundary (or even more so in a corner) as these
conditions can tend to artificially boost the response (boomy) and
deteriorate the transient details or speed.

EQ
This control allows you to adjust characteristics of the subwoofer
to match the main speakers in your system. EQ “equalization”
aims to provide tuning to get the best overall response and
seamless integration of your speakers and room.
SUB EQ
The subwoofer has a switch marked with “EQ”, this allows you
to choose between three different EQ “Characteristics” settings
allowing you to get the very most out of your subwoofer when
used for these very different applications.
•
MUSIC
mode gives an extended frequency response for the very
deepest octaves of bass. The energy produced at these very
lowest frequencies requires extraordinary levels of cone excursion and power, but when
setup correctly will give high-quality recordings a completely new dimension you may
have never before experienced.
•
MERLIN
mode has been exactly tailored to allow a seamless audio experience from
Merlin’s tight bass response deep down by approximately an additional 1.5 octaves. The
phase and magnitude response has been matched specifically so that you can combine
these two products as the perfect complement allowing you to cover the entire audio and
subsonic spectrum with no compromise.
Setup together you will experience performance usually only found in the very highest
quality active integrated loudspeaker systems, you will experience an extraordinary new
sense of dimensionality and atmosphere without compromising musically, transient
emotional content, detail or a sense of point source”. This is a Richter experience at its
best, you will be guaranteed to want to hear all those tracks over again with a renewed
enjoyment, excitement, and love that Richter is now famous for.
•
HOME THEATRE
mode optimizes the subwoofer’s performance to maximally cover
requirements for both deep but also the extremely dynamic bass requirements of the
very latest formats.
The picture below shows the effects of the different EQ settings.
(These curves illustrate the frequency response of an anechoic room, have in mind that the
frequency response will change depending on the room and placement of the subwoofer
and listing position, these graphs provide a relative representation.
E.g. A setup in a regular room with the Home Theatre mode could have a total frequency
response that extends much lower than represented in the graph below due to room gain.
