    Owners Manual
    Thank you for purchasing these Acoustic Energy Radiance
    Series loudspeakers.
    These high-performance loudspeakers utilise some of the
    fnest materials and most advanced technology available.
    They are voiced according to Acoustic Energy’s core values
    of musicality, timing, neutrality and, above all - realistic
    reproduction of the source material.
    More than any other Hi-Fi product, speakers are sensitive
    to installation so please take a little time to read this manual
    and follow, where practical, the guidelines it contains.
    Careful installation will help ensure that your Radiance
    speakers perform optimally. Should you have any questions
    not covered here please take a look at the support section on
    our website - www.acoustic-energy.co.uk
    Radiance Series loudspeakers should provide years of
    maintenance-free enjoyment and are guaranteed against
    defects in materials, manufacture and workmanship for three
    years from the date of purchase. For full details please refer
    to the Warranty section on page 5 of the manual.
    This manual covers all Radiance Series except Radiance Sub.
    The Radiance Series loudspeakers incorporate various
    advanced technologies, including -
    · Aluminium drive units
    · Ring-radiator tweeters
    · Curved, acoustically braced cabinets
    · DXT® lens
    Most interesting of these features (and a frst for Acoustic Energy)
    is the DXT® lens. This adjusts dispersion from the tweeters to
    match that of the mid/bass drivers.
    The lens improves two components of the sound -
    Firstly, integration between high and low frequencies is more
    natural and seamless than in conventional speakers. This is crucial
    for realistic reproduction of the midrange - the human voice in
    Secondly, the lens creates far better integration of sound into the
    room environment. This integrated sound is more expansive and
    “live” than you would usually hear from a conventional speaker,
    while remaining easy to listen to. Detail is abundant but always
    part of the musical whole. 
    Handling - Loudspeakers are relatively delicate, precision
    engineered products that can be damaged by inappropriate
    handling. Please take care when unpacking or moving them
    not to touch any of the drivers. Damage to a driver will at
    best degrade performance and at worst result in complete
    Set Up - Radiance one - Ideally the Radiance ones should be
    mounted on dedicated speaker stands tall enough to place
    the tweeter at, or slightly above ear level from a seated listening
    position. The use of wall mounting via brackets or shelf/cabinet
    placement are viable alternatives, though performance in these
    locations may be reduced from the optimum.
    Radiance two/three - As foorstanding speakers both models
    require placement clear of room boundaries and should be
    mounted on spiked feet (supplied) for best performance. If
    spikes are inappropriate for your foor covering, metal
    protection pads, coins for example, may be used between the
    spike and the foor.
    Radiance centre - For use in home theatre systems either
    directly above or below the screen. The centre can be stood
    on a furniture unit (using supplied rubber feet), integrated
    within a screen stand, mounted on a dedicated speaker stand
    or on a wall using appropriate bracket hardware.
    Each Radiance Series speaker has two pairs of binding-post
    terminals. These terminals can accept either stripped wire, spade
    connectors, or 4mm plugs. Each of these termination methods are
    potentially equally efective and the choice is likely to be infuenced
    by the type of speaker cable used. Your dealer, distributor or cable
    manufacturer will be able to ofer advice.
    The two pairs of binding posts are mechanically joined via gold-
    plated bridging links and can be single or bi-wired.
    Simply connect the speaker cable to the correct polarity terminal on
    the speaker (positive - red, negative - black). Either top or bottom
    terminals can be used. Ensure the speaker cable is attached to the
    amplifer in the correct polarity before use. (Note - you will have two
    unused terminals, one red, one black on the speaker when wired this
    way, this is correct when the bridging links are in place)
    To bi-wire you will need to unscrew the caps on the binding posts
    and remove the bridging links before connection. There are multiple
    ways to bi-wire/bi-amp a speaker, consult your Hi-Fi dealer for the
    best advice on how to do this with your particular system. They will
    also be able to advise on cable choice to best match your system. 
    Home Theatre Positioning
    Room layout has a large efect on home theatre systems
    due to the number of speakers involved. Below is a
    diagram of an optimal layout, this may be hard to achieve
    in a typical home so it is worth trying to stick to a few
    general points if possible -
    · Front left and right speakers should be equal distance
    from the centre speaker
    ·Try to place the front left and right speakers a reasonable
    distance apart (where possible) to create a good spread of
    · The height of the rear speakers is not as crucial as the
    fronts, they are mainly used for efects and atmosphere
    Typical optimum home theatre room layout
    Stereo Postitioning
    Speaker interaction within the room environment is one of the
    largest factors with regards to its performance, having even more
    infuence on sound quality than a change of source or amplifcation.
    In an average sized and furnished listening room (say 4m x 5m) you
    should aim for a few basic positional points of reference for speaker
    placement* -
    · Between 0.2 and 0.6 metres from the rear wall
    · Between 0.4 and 0.8 metres from side walls
    · Between 2.5 and 3.5 metres apart
    · Clear of corners
    · Maximum toe-in of 15° towards listening position
    *These are guidelines only - positioning should be tailored until you fnd a preferred sound in your room.
    Typical optimum stereo room layout 
    It is wise before listening to your speakers to make one fnal
    check of the cables and connections. If all appears well, begin
    listening at a relatively low level to confrm the system is
    operating as expected. Only increase the volume if you are
    happy that the sound at low levels is fundementally as
    expected. If you are not convinced all is functioning correctly,
    turn of the system and re-check all the cables and
    If you are concerned about any aspect or operation of the
    system consult your Acoustic Energy dealer or distributor for
    further advice.
    Radiance Series speakers may take a little time to “run-in”, and
    similarly the system will also take some time to reach normal
    operating temperatures. It is unwise therefore to make rapid
    judgements about the performance of the speakers. Your ears
    too will take some time to adjust to a new sound, so revisiting
    the system set-up, speaker positioning especially, is best left
    for a few days.
    Always try to begin listening with the speakers where you feel
    they will perform best, facing straight on while sat in your
    main listening position. From there adjust toe-in and foor
    placement to optimise the sound to your preference.
