Both Gordon Holt and Doug Sax (both mentioned above) eventually discovered active ATC. ATC are the speakers they used daily until they passed away.
The tone of the Spendor S 3/5S is mainly the polypropylene cone - the plastic is quite flexible and they tend to roll off early. A polite upper mid range BBC dip is the characteristic tone - not as lively as other materials. Harbeth and Rogers and other plastic cone speakers tend to share this tonal character.
