Replacing Wharfedale W60D woofers

[Sounds Right]

May have to replace a woofer for W60D speaker. Several on E-bay advertised as being for W60D’s. But some have square magnets, some have round magnets (like mine), some say they are 4ohm, some say 8 ohm. Some say ‘longer throw style—for early tube systems”…lots of variances in the woofers stated as being out of W60D’s…..and there is a set out of W60’s…that look just like the woofs in my W60D’s.
Educate me here….did they make several slightly different woofers for the W60D’s…depending on year of manufacture? Are W60 and W60D woofers the same? Do I need a particular W60D woofer? My speakers themselves say 4 -8 ohm on the L Pad Plate, and have ’67 written on the woofer cones. Is there a model or serial number somewhere that would more specifically identify my woofers?
If there is some cross capability among different W60-W60D woofers…..would some be considered superior to others?

I think the main difference between early and late W60... woofers are their efficiency. I have a pair of W60E (ca. 1971) and they require a lot of power to get them moving. I listened to a pair of early W60 (early 60's design) and they are much more efficient, which is to be expected since they were deigned for tube amps or early low wattage solid state.

I believe that the W60D was the first sealed cabinet "acoustic suspension" model of that series. Earlier ones were all ported.

I can't speak to round or square magnets, but the surround is the critical issue. Many early W60 woofers used a gauzy cloth surround. I think you will need the later ones, with a rubber surround, to maintain the seal in your cabinets.
