Congratulations on choosing the Acoustic Energy AEGIS
THREE — a powerful floorstanding three-way loud-
speaker 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 perfor-
mance out of your Acoustic Energy loudspeakers.
The AEGIS THREE utilises metal cone mid 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 LF unit incorporates a larger polypropylene cone with a
critical flare which gives efficiency and rigidity to ensure a con-
trolled yet fast bass response. It is housed within a vented
polymer chassis reducing stray magnetic flux to a minimum
and increasing power handling.
The tweeter — or treble driver — is a high-quality silk fabric
dome unit 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 AEGIS THREE loudspeaker uses high quality OFC internal
wiring which enhances detail and transparency. For exceptional
results use AESC-C3 speaker cable which is available from AE
dealers and distributors.
Please unpack your AEGIS THREEs 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 this
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 fre-
quency 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.
Experiment with the best position to achieve a full, yet clean
bass response. Trust your judgement and ears. For serious listen-
ing the grilles are best removed.
For best stereo imaging the speakers should be as far apart as
they are from the listening position.
