    As far as I know, ABL was mainly developed to lift the ‘presence’ of bass in the lower volumes.
    So I think that relatively seen, it does not boost bass in the higher volumes.

     

    Probably there are other forum members who know more about ABL. Please comment.

    Don’t worry about de-attaching the front panels and the glue strips holding them.
    Obviously, you will first have to remove all screws. After that, the glue strips will hold the speaker driver panel and the PSU/AMP panel in place. The glue strips function as gaskets.

    Nevertheless you can push a flat hand screw driver (actually & literally with a flat head), just underneath the panel, and push it up a bit. Do it slow, and as soon as it comes a Biot loose, move the flat head down a few centimeters, and so on.

    “In the meantime do you know if not using them will slow down the process (less heat) or as this nothing to do?”

    The heat inside the cabinet makes the foam deform. As Long as you do not use them, the process will of foam rot will not continue. Be aware though that the damage might already have been done. Some times, some of the copper tracks on the PSU PCB are eaten away. And sometimes that’s even hard to see with the eye. But this is easy to solve with some by-pass wires.

    Hi Matador,

    Foam rot is a serious thing as it can damage the pcb and electronics, causing malfunction, etc.

    I am not completely sure about which serial number has the improved foam, but I think 12xx xxxx might still have the old foam.

    My advise for proper action is not to apply self cut pieces of plastic. This will not help, because when foam rot is there, it is already damaging the pcb and components. The only way is removing the old foam and thoroughly cleaning the pcb and components.

    Thanks very much for this suggestion Christian. Very helpful to know!

    At the moment, I am quite sure I will be able to get the mid-tone driver alive and well again. So I will proceed to find the appropriate glue for attaching the dome back to the tape on the metal ring of the mid-tone driver.

    If you have an advice about the right type of glue, I am open to hear.
