A12P bezel cover

[bqc]

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.

Are you saying I can't use my precision instruments Mark?

Ah yes, the "brummy screwdriver". That takes me back a while.

I received a pair of 12P's from Madisound Friday from the latest production, and the covers were not glued on. Did something change where the alignment sensitivity is no longer as much of a concern?

You have the option of using the cover of not. Mark recommends using the cover if possible. There is a sticky thread that discusses glueing the cover to the driver frame.

Thanks Bob, and I understand that is the case with other MA drivers but the second post in this thread is from Mark saying the cover on the 12P is bonded at the factory because it is required due to alignment sensitivity.

Mine didn't come bonded. Why not?

Could anyone actually post a picture about this bezel cover?
A pair of 12Ps are on the way and i don't want to mess anything up upon receiving them.
Thanks

Bump... still looking for an answer.
