    							Congratulations on choosing the Acoustic Energy AESPRIT
    309, a powerful floorstanding three-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 309 utilises metal cone mid and 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 units are housed
    within vented polymer chassis reducing stray magnetic flux to a
    minimum and increasing 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 309 loudspeaker uses quality OFC internal
    wiring, which enhances detail and transparency. 
    Please unpack your AESPRIT309s carefully. Locate the plinths and
    fittings and, having carefully inverted the speaker, screw the plinth to the
    base of the cabinet using the screws and pilot holes provided. Please
    take extra care during this operation, as the cabinet is top-heavy when
    inverted. Please also ensure that you have tightly screwed the plinth to
    the cabinet. Failure to do so will affect performance.
    High tensile 8mm floor spikes and lock nuts are provided for use with
    the plinth. These guarantee optimum coupling to the floor particularly in
    rooms fitted with carpet. The spikes penetrate the carpet and couple the
    speaker firmly to the floor structure below. The spikes (with lock nut
    screwed down to the knurled part of the spike) should be fitted to the
    threaded insert in the underside of the plinth while the speaker is still
    inverted. The speaker is now ready for installation. Any final adjustment
    of spikes to eliminate cabinet wobble can now be made using a spirit
    level if required. The lock nuts should be tightened when the final
    adjustments to cabinet position and alignment have been made.
    Closeness to room boundaries has a major impact on the low frequency
    performance. The speakers should be kept away from corners (which
    will produce booming) and there should be at least a 300-400mm (12-
    16 inch) gap from any back or side walls.
    In the rear port of your AE309 you will find a foam bung. This has been
    supplied for tuning purposes to allow for differing room acoustics and
    positioning. Removal of this bung will give an increased bass output
    where required.
    Experiment with the best position to achieve a full, yet clean bass
    response. Trust your judgement and ears. For serious listening the grilles
    are best removed.
    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/mid section of both loudspeakers; a second drives the
    bass sections. 
    Note that the shorting links must be removed.
    Failure to do so will result in damaging the amplifers.
    As regards the loudspeakers, wiring for bi-amping is achieved in much
    the same way as bi-wiring. Treble/mid amplifier positive (red) terminals
    should be connected via the ribbed cable to
    the positive (red) HF terminal on the speaker.
    Similarly, treble/mid amplifier negative is
    connected to the negative (black) HF
    terminal on the speaker. Repeat this process
    with the 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/mid and 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/mid and
    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/mid section and one to the
    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.
