DIAGRAM 3
• The low frequency balance of a loudspeaker is heavily influenced by the room. If the balance is bass heavy/bass light, experiment with positioning
and apply room treatment before resulting to equalisation.
• If there is no solution but to apply external EQ, please consider:
– Cut is best! Boost EQ should be used in moderation as it will reduce loudspeaker amp headroom and available driver excursion.
– Taken to the extreme boost EQ could lead to damage of the loudspeaker.
– Nulls in the response due to room modes can’t be successfully equalised.
– EQ can’t deal with the variation in response at different room locations.
• The physical space EQ will be successful over is inversely proportional to frequency – ‘EQ space’ gets smaller as frequency increases – so this
leads to a practical limit of around 200Hz.
The install variant is constructed with a steel corner braced cabinet and fitted with 4 x M8 mounting points in the rear face. These are positioned
in standard 69.9mm x 127mm / 2

˝ x 5˝ rectangular pattern. These points are fitted with M8 x 30 Button Head fasteners which should be used when
fixing to your chosen mounting bracket. The pitch of the fixing points is illustrated in diagram 12. The fixings are compatible with (but not limited
to) the following widely available mounting brackets and adapter panels:
• Adaptive Technologies – MM-022-BT, MM-024-BT, MM-060, MM-018 , MM-3RDX-18.
• Konig &Meyer (K&M) – 24481 wall mount, 24496 ceiling mount, 24352 adapter panel 1.
– Ensure that all mounting hardware is rated for loads greater than 19 .3k g / 42 . 5l bs.
– Ensure that the wall or ceiling structure being fixed to can support the load of the speaker & bracket, including a safety margin.
– Mounting and/or suspension of any loudspeaker should be carried out by an experienced professional. Improperly installed loudspeakers can
result in damage, personal injury and/or liability to the installing contractor.
– The SCM25Ai Pro is fitted with a safety anchor point, in the form of a single M8 eyebolt situated at the top rear corner as illustrated in diagram 3.
In addition to the primary mounting fixings, this eyebolt MUST be tethered to an appropriate safety point in all installations, without exception.
