    Small problem. How do I get into my Goodman Magnum K2s?

    Obviously I can from the front via the drivers but no room to work that way.

    The rear is locked down with glue and stuff. Should I just go for it with a Stanley knife and lever the rear off with force? I'd rather do this neatly. After all the speakers are super valuable. Got them for 20 I think.

    Based on some personal feedback and helpful tuition from Lawrence he says I should not open the rear but instead do all necessary work via the driver holes. So that is what I will do, firstly remove/desolder all the drivers and then the wadding. Need to find some time.

    Watch this space.

    Some progress

    Removed old crossovers and wired up speaker drivers for direct input.
