The A12P came with cover that looks like it is already glued on? or do I need to glue it to secure it? How do you pop it off? it looks like it is on pretty tight

Hi Bqc (guys)
The Alpair 12P's front cover is bonded to the frame at the factory. DON'T remove this cover. The power train on this driver is particularly alignment sensitive, requiring cover and frame remaining together. In mechanical terms, the 12P is a "semi-free to air" design with the rear suspension doing the bulk of support/excursion - see Jpeg. So take your time when fitting this (and all Markaudio drivers for that matter) into your box: 1 - Make sure the mating surfaces are flat. 2 - Pilot drill the securing screw holes before fitting the driver. 3 - Carefully and evening tighten the securing screws. For those of you who are engineers, use a "star" sequential tightening pattern. 4 - DON't over-tighten the securing screws. Just a gentle nip-up is all that's needed. Power screw drivers aren't recommended. Use a good quality hand tool - see Jpeg. 5 - Use your eyes. Look low across the front baffle and front of frame. Check to see they are both level. Any distortion in the frame, ease the screw back a little until level. Thanks Mark. Last edited by markaudio; 26th October 2012 at 11:18 PM. Reason: additional info |
