I recently purchased a pair of Cornwalls and a pair of Heresys. Both are coded R so I think that both sets are of similar vintage. The top end of the Heresys is much more clear? The top end of the Cornwalls sounds distant and dull. The Cornwall horns are the same as the horns used in the Heresys. I pulled the back off of the speakers to find the Heresys to not have any stuffing, is this normal? The stuffing in the Cornwalls looks like paper and it also looks like mice have enjoyed themselves living in the comfort of the plywood boxes. The crossover capacitors are metal oil filled, they look original. Tips on speaker stuffing, capacitor selection, stands, anything to get my speakers performing the best that they can would be of valuable.
