LE10H foam glued on the front of cone

I bought a pair of 4313B with new foam on the LE10H woofers. But instead of being glued to the backside of the cone they are glued to the front. Is there any sonic difference ? I think that the spider is so stiff that the voicecoil is still correct in the gap.

Nice score on rare 4313B in our old Europe, sadly they managed thômiss the refoaming. I don't think you'll notice anything, hard driven I barely see my LE10H moving. Wait until you need refoaming in years and enjoy records ;)
