    							Congratulations on choosing the Acoustic Energy AESPRIT
    300c, a powerful compact two-way loudspeaker which
    features metal diaphragm technology and is capable of
    outstanding performance. Please take a few moments to read
    this manual.  The advice it contains will enable you to get the
    very best performance out of your Acoustic Energy
    loudspeakers.
    The AESPRIT 300c utilises metal cone mid-bass drive unit technology,
    proven in the AE Reference series. The rigid anodised alloy cone ensures
    pure piston action and also acts as a heat sink for the bonded voice coil.
    These features provide exceptional clarity, transparency, dynamics and
    power handling.
    The tweeter - or treble driver - is a high-quality neodymium unit with a
    silk fabric dome integrating smoothly with the rest of the system.
    All drive units are fully magnetically shielded so that the speakers
    can be used in close proximity to a TV screen or monitor for AV
    applications.
    The Acoustic Energy AESPRIT 300c loudspeaker uses quality OFC
    internal wiring, which enhances detail and transparency. 
    The AESPRIT300c speakers are best heard with the tweeters at, or just
    below, ear height when the listener is seated. For serious listening the
    grilles are best removed.
    Rigid support is essential for the speaker to develop its full detail and
    dynamic performance. Rigid stands with spikes, cones or other methods
    of secure mounting are recommended. ‘Free-field’ stand mounting gives
    improved stereo separation and depth. If 
    AESPRIT300c speakers are
    shelf mounted the support must be firm; cones are still recommended
    beneath the cabinets.
    Closeness to room boundaries has a major impact on the low frequency
    performances. The speakers should be kept away from corners (which
    will produce booming). The speakers can be positioned fairly close to a
    back or side wall but should not be the same distance off the ground as
    from the rear or side wall.
    Experiment with the best position to achieve a full, yet clean bass
    response. Trust your judgement and ears.
    For best stereo imaging the speakers should be as far apart as they are
    from the listening position.
    Positioning Introduction 
    						
    							Bi-amping
    Bi-amping adds a second amplifier to the system. One power amplifier
    drives the treble section of both loudspeakers; a second drives the
    mid/bass sections. 
    Note that the shorting links must be
    removed. Failure to do so will result in damaging the
    amplifiers.
    As regards the loudspeakers, wiring for bi-amping is achieved in much
    the same way as bi-wiring. Treble amplifier
    positive (red) terminals should be connected
    via the ribbed cable to 
    the positive (red) HF terminal on the speaker.
    Similarly, treble amplifier negative is 
    connected to the negative (black) HF
    terminal on the speaker. Repeat this process
    with the mid/bass amplifier and LF terminal
    pair.
    After wiring up
    Lower the volume to the minimum,
    switch on the amplifier, select the
    signal source and then raise the 
    volume to the listening level required.

    RLMAIN
    Check that your amplifier is switched off before installing your 
    loudspeakers. Failure to do so may result in speaker or amplifier
    damage. The diagram illustrates one loudspeaker only.
    Conventional
    Normal passive wiring requires shorting links to be in place between the
    treble and mid/bass sections. The positive (ribbed) cable from the
    amplifier positive (or red) terminal should connect with the positive
    (red) terminal on the loudspeaker. Similarly the negative (smooth) cable
    should connect the amplifier negative terminal (black) to the negative
    terminal (black) on the loudspeaker.
    Bi-wiring
    Bi-wiring separates the bass and treble ground paths in the loudspeaker
    and offer sound quality advantages. An extra set of cables is required.
    Note that the shorting links are removed between the treble and
    mid/bass sections and should be stored for later use if conventional,
    passive driving is required.
    Two pairs of cables are connected to the amplifier terminals. One cable
    of each pair should connect to the treble section and one to the
    mid/bass section. The positive (ribbed) cables from the amplifier positive
    (or red) terminal should connect with the positive (red) terminals on the
    loudspeaker. Similarly the negative (smooth) cables in each pair should
    connect the amplifier negative terminal (black) to the negative terminals
    (black) on the loudspeaker.
