Apogee front cover removal

I recommend you have another person present to help you the first time you do this. I could manage Duetta Signatures on my own, but you do need to be careful as you will be completely exposing the ribbons. Make sure the other person is aware of how delicate they are.
Also have a piece of stiff cardboard roughly the same size as the speaker ready. This is for protecting the drive units when you have removed the cover.

Lie the speaker carefully on its side (get someone else to hold it for you) and remove the aluminium supporting legs, as one of them covers a screw holding the front on.

Get a thick book or a small strong box about 2in high to use as a support. Turn the speaker over onto it's back and slide the book or box under the top of the speaker, so it is supported by the book/box at the top and the speaker terminals near the bottom. This gives some clearance from the floor which helps as the front hooks over 2 metal pins in the top of back frame and it can be difficult to get back on if it's sitting flat on the floor. 

Remove the 2 screws in the base of the speaker, this is all that holds it on.

This is where the another person is very useful. Once you see how the cover attaches you can do it quite easily by yourself as the cover isn't that heavy, although I recommend two people for Diva covers due to their size.

Note 1: Make sure that both of you don't have anything in your pockets that can fall onto the speakers when you are removing the cover. Or any over enthusiastic pets that can run into the room!

Lift the front cover from the bottom edge, you will hear a tearing sound as you lift upwards, DON'T PANIC! The sound is due to small pieces of Velcro which hold the front in place. Have the other person holding the top edge of the front cover, make sure they know to keep their hands clear of the midrange/tweeter. (Saves any excessive swearing/violence/divorce proceedings etc)
Once you have lifted it about 6-8in, so the Velco is unhooked,  push the front gently towards the person at the top, they should then be able to lift it clear as this unhooks the top from the metal pins.

Put the cover to one side, you now should have a " naked" Apogee.

You may find that some of the Velcro tabs come away from the cover or the speaker itself. If you need to reattach any you can use some ordinary contact adhesive.

Interestingly you will probably find a date on the top wooden clamp which will tell you exactly how old the speaker is.

Note 2: The top and bottom clamps of the bass panel will be slightly loose, this is normal. They are left that way to give some freedom of movement to help prevent stress fractures in the panel.

If you want you could now reattach the support legs. This way you can work on the speaker in its normal upright position, this is easier and also safer. 
Get the other person to carefully hold the speaker upright on it's long side while you re-attach the support legs. When you have done this you can stand the speaker back up again, also you can easily temporarily replace the cover.
I found the Velcro held the front well enough on my Duetta Signatures to use them without needing to reinsert the screws in the base, some people have experienced buzzing/rattling when the fronts are not screwed down however.
