Audio Advice Radius Series Bookshelf Speaker
Introduction
Congratulations and thank you for your purchase of the Radius Series
loudspeakers. We are confident they will provide years of enjoyment and
pleasure as only high-quality components have been used throughout.
Please follow this user manual carefully as it contains important information
about positioning and setup procedures. For further advanced information
please refer to our web site at:
www.monitoraudio.com
WARNING: The Radius 45 incorporates a thermal protection device, which helps to protect the drive unit and tweeter from permanent damage. If the speaker stops working after a long period of play, turn off the source for about 10 minutes, and retry.
Set Up and Positioning
Although position and suitability will have been considered prior to purchase
these loudspeakers, this section will guide optimum positioning and set up (an
illustration is provided on page 4 to assist with positioning). For
instructions on fitting the Radius 225 or Radius One to a wall, please refer
to page 5. The Radius One features fixings compatible with a Sanus Wall
Bracket.
NOTE: The Radius 45 and 90 can be fixed to a wall using our Universal
Speaker Mount sold separately. The Radius 200 is not designed to be wall-
mounted.
Self-adhesive rubber feet are provided to prevent movement due to vibration
when using the Radius Series loudspeakers on a table/ equipment stand. The
Radius 270 comes supplied with rubber feet fitted into the plinth for use on
hard floors. Further details on these can be found on page 10.
Radius One
The Radius One can be placed either just below or just above your TV/
projector screen. It can be wall-mounted with the supplied bracket (refer to
page 5), or alternatively using the Sanus VMA202 Soundbar Speaker Mount. refer
to www.sanus.com for further information.
Radius 200
The Radius 200 is the range’s first dedicated centre speaker and is designed
to be placed on a shelf or cabinet.
Positioning – Front Speakers
The centre channel should be the first speaker positioned in a home theatre
room, and such that the tweeter is directed towards the listener’s ear. The
centre channel’s job is to anchor dialogue and other on-screen sounds to the
screen. Typically, as much as 60% of a movie soundtrack comes through the
centre channel.
The centre channel can be placed either above or below the TV screen and as
close as possible. If positioned in a cabinet or sitting on top of the TV,
ensure that the front edge is aligned with the front edge of the TV or shelf.
Where possible, the height of the centre channels’ tweeter should be close to
the height of the front speakers’ tweeter — ideally, within about 600mm.
When placing Radius loudspeakers on the wall around a plasma/ LCD TV, the left
and right speakers need to be between 22 & 30° to the left and right of the
seating position, with the tweeters at approximate ear level.
Positioning – Surround Speakers
Ideally, the primary pair of surround speakers should be placed to the left
and right of the listening position — either in line with it or just behind it
(90 – 110°). If using a 6.1 or 7.1 channel system with more than two surround
speakers, or if side placement isn’t available in a 5.1 channel system,
consider placement behind the listening position, facing the front of the room
(135 – 150°).
Surround speakers should be placed high enough so that the drivers do not fire
directly at ear level when sitting down — one rule of thumb is to place them
at ear level while standing, to avoid overpowering the front speakers.
If the surrounds are mounted on brackets on the sidewalls, experiment with
aiming them.
Surround speaker placement ideal for home theatre, may not necessarily be so
for multichannel music listening, where a precisely focused rear soundstage is
best. If both types of listening are important, position them as a compromise
between the two.
Optimum Speaker Placement
Fixing the Radius 225/ Radius One to a Wall
Additional Points to Remember
- When using the wall fixing plate, the speaker will drop by 7.5mm due to the keyhole fixing.
- Templates are supplied with the products to aid fixing.
- The Radius 225 grille badge can be rotated, simply by applying some pressure with your thumb/ finger and turning.
- Please allow no more than 100mm (4 inches) of excess cable protruding from the wall. Any excess cable can be coiled inside of the terminal panel.
- Please see the template for suggested rubber foot placement.
Radius 270 Feet and Spikes
- If using spikes, first remove the rubber feet by simultaneously twisting and pulling them out, revealing the threaded inserts.
- Take the spikes and twist them in a clockwise direction into the plinths. Ensure they are fully inserted, stand the cabinet up and place it in its final location. To level, adjust the spikes accordingly, before finally tightening the knurled locking nut to hold the spikes in that position.
