+1 on bill at millersound being among the very best
he restored a set of woofers for my spendor sp1/2e’s - he said he was using a strong yet compliant german surround material and the speakers would play even nicer than the originals as a result
i obviously didn’t have the originals in new condition to compare anymore, but i really think the speakers sounded better, dug a little deeper into the details and nuances in the mids and bass when i reinstalled the rehabbed woofers
and all that at a very reasonable price... 🙇♂️🤗
