Jimjenjr...My second loudspeaker (circa 1955) was a 12 inch Wharfdale full range. I put it in a folded horn corner enclosure that I built. The interesting thing about this driver was the wool flannel cloth surround. (Really low Fs). Foam came later. It was driven by a Dynakit preamp and power amp (tubes of course) and was just about SOTA.
Of course Wharfdale was also famous for sand-filled enclosures.
