manual abstract
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 AEGIS EVOLUTION speakers utilise metal cone bass and mid-bass drive unit technology, proven in the AE Reference series. The ultra rigid ceramic layered alloy cones ensure 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 tweeters, or treble drivers, employ a high- quality silk dome unit, built on a metal chassis, 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 EVOLUTION loudspeakers use quality OFC internal wiring, which enhances detail and transparency, and may be bi –wired as desired. Positioning Experiment with the best placement in the room to achieve a full, yet clean bass response, a natural sounding mid range and a balanced spacious stereo image. Trust your judgement and ears. For best stereo imaging the speakers should be about as far apart as they are from the listening position. The speakers should be equally distant from the listener[s] and should not be too close to large items of furniture which may cause sound reflections. Ideally they should be about 1m from the side walls and about 0.7m from the wall behind. The spacing of the listening seat to the back wall may be quite critical for a smooth deep bass. Aegis Evo One The AEGIS EVO ONE is best heard with the tweeters at, or just above, ear height when the listener is seated. For serious listening the grilles are best removed when the greatest clarity results. Rigid support is essential for the speaker to develop its full detail and dynamic performance. Good quality metal stands fitted with spikes, cones or other methods of firm mounting are recommended. Stand mounting, placed as recommended gives best stereo separation and depth. If AEGIS EVO ONEs are shelf mounted, the support must be firm; cones, or felt pads are recommended beneath the cabinets to reduce vibration coupling to the support. Good quality wall brackets may be used, designed for speakers of this size and weight. If wall mounted keep 1.5m from the side walls and angle the speaker towards the listener area if possible; note that a corner position is the poorest sounding for any speaker even if it is the loudest. AE can supply damping plugs for the rear port to moderate the bass on request. Positioning Aegis Evo Three Please unpack your AEGIS EVO THREE carefully on a carpet or similar surface. 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 ensure that you have firmly screwed the plinth to the cabinet, failure to do this will degrade performance. There is a mass-loading compartment at the bottom of the cabinet. You may choose to fill it with washed, fully dried non salt contaminated sand, or suitable metal chips, via the hole at the back. A plastic bung is provided to seal the cabinet. Mass loading will significantly improve the performance of the speaker. If you decide not to mass-load the speakers, we still recommend fitting the plastic bung to avoid unwanted resonance. Be aware that the plastic bung has not been designed to be removable after insertion. You may wish to use a temporary removable plug until you have made your decision High tensile 8mm floor spikes and lock nuts are provided for use with the plinth. This guarantees 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 firmly tightened when the final adjustments to cabinet position and alignment have been made and there is no rocking. Closeness to room boundaries has a major impact on the low frequency performance. The speakers should be kept away from corners (which will produce bass booming) and they should be 0.6 m from the back walls, and a greater distance e.g. 1m from the side walls. Aegis Evo Centre Position the AEGIS EVO CENTRE either immediately above or below the television screen, whichever places the speaker nearest ear level when listening. Line the front of the speaker approximately in line with the plane of the screen. Fix the four self-adhesive foam-rubber feet to the base of the speaker to protect both the surface on which the speaker stands and the underside of the speaker. The feet also...
