Do any 4312A owners out there know how to remove the crossover network? I want to replace some caps, but I'm having a hard time getting the crossover out. I've even tried using a mirror to see way up in the corner, but to no avail. I can't find any screws or other fasteners up there.

Thanks in advance!

If I remember correctly, you have to remove the foilcal on the front of the speaker. There are screws located underneath the foilcal.

I was afraid someone was going to say that. I can't see how I can remove it without doing irreparable damage, though.

Any other options? Anyone?

I'd use something highly flammable to remove it Sparky...

Use a heat gun, or a blowdryer will work, to soften up the adhesive...then carefully work a thin, wide blade putty knife under the label to lift it up. Just go slow and easy so as not to damage the label. Another way is loosen the adhesive with a penetrant like WD-40 or an orange-based remover and work it off, then clean off the penetrant with rubbing alcohol and use a spray glue (3M Super 90) to reattach.

Hope this helps....good luck.

Thanks for the advice, everyone. I'll probably try the blowdryer method and keep my fingers crossed!
