Acoustic Energy Loudspeaker AE300c User Manual

							Owner’s manual 
						

							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.

FOR FUTURE USE
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.
