12. allations the orientation of the speaker is not crucial but we do recommend positioning the top of the speaker closest to the walls of the room and to mirror this with the alignment of any speakers that are on the other side ofthe room For critical listening in ceilings e g a 51 surround system ensure that the orientation of all speakers is the same relative to the main listening position and position the top of the speaker closer to the walls System Requirements From a system compatibility point of view your AIW350E and its accompanying APU protection unit can be treated like any conventional 6 8 Ohm loudspeaker Amina recommend you use a good quality amplifier so as to avoid driving them with high levels of distortion which at best will provide poor sound quality and at worse may permanently damage the loudspeaker Amina also recommend you connect the AIW350E to your amplifier with at least 16AWG OFC oxygen free cable 14AwG for long runs to avoid any chance of reduced efficiency and audio bandwidth For 21 51 and 71 systems always use the amplifier s crossover settings to divert frequencies below 100Hz to your subwoofer This will improve the dynamic range and power handling of the system APU2 and APU RS8 should still be used MPORTANT AIW350E speakers are highly revealing of any shortcomings in the source or amplifier Please be aware that some low powered and some higher powered zone ampli

32. to the above characteristics the radiating surface of the AlW350E is very stiff and undergoes very small amounts of movement in order to generate high sound pressure levels This means that the AlW350E is inherently fast making it a highly articulate loudspeaker Wall or Ceiling Placement The AIW350E is suitable for both wall and ceiling installations When the most uniform audio coverage in a room is required space the speakers evenly in the ceiling However if the room has a height greater than 6m 19 Amina suggests installing them in the walls at a height of around 1 8m 6 In dedicated listening rooms where AIW350E speakers are used in stereo or multi channel systems position them in the walls so that the centre point of the AIW350E is approximately 1 1 8m 3 5 6 from the floor This will give excellent results but don t worry if this is not possible to achieve in your room as the audio characteristics of the AIW350E make exact positioning according to stereo 5 1 7 conventions far less critical 26 Setup tips Speaker Orientation The AIW350E can be installed either in portrait or landscape orientations Typically the spacing between wall joists will dictate the portrait orientation and we have optimised the dispersion characteristics for this setup Therefore when installing into walls we suggest the portrait orientation for best sound quality For non critical listening in ceiling inst
