I've read through quite a few threads here about refoaming these LE14a's. Didn't seem to find anything definitive as to whether the surround should go on the front or back of the cone. Seems like it works ok either way.
The new surrounds won't completely cover the area where the old foam is attached and it seems like it would be extremely unlikely that I could get all the old brown glue off without damaging the Aquaplas on the front of the cone. I've trimmed all the old Lansalloy back to a nice smooth edge at the cone edge, but haven't tried to remove it any further. It looks quite nice with the new foam test-positioned on the back.
The new foam weighs 5grams... the roll part of the old surround, which came off intact, weighs 3 grams... I'd guess the complete old surround would have weighed at least 6 to 7 grams. So, leaving the inner part of the old surround would add 1 or 2 grams to the cone weight.
I'm wondering if anyone has left the Lansalloy partially on the front of the cone and glued the new foam surround to the back?
