Well I could scan the text from the old Gilbert Briggs book but as it's
you Keith I won't bother

Has anyone reprinted this recently? I think I have an old copy at work, but
am not sure as I haven't checked recently.

All the Wharfedale drive units, (like the Goodmans Axiom 301s and Audiom
61s that I like so much) were made in a number of variations.

Yes, I think this is correct. There are probably models that look similar,
or have similar/identical names, but may differ in details.

I have a circa-1964 Warfedale leaflet on the "concrete column speaker" that
lists:

Super 8/RS/DD
resonance 55 c/s, Pole dia 1 inch, flux density 14,500 Oersteds, Weight
4.5 lbs.

Similar vintage Warfedale gatefold leaflet leaflet lists:
Super 8/RS/DD
Impedance 10/15 Ohms, Pole 1 inch dia, Freq range 40 - 20kHz, Aluminum
voice coil, Roll surround and double diaphragm, Weight 4.5 lbs.


If anyone is interested, I've put more details on a webpage at
http://www.st-and.demon.co.uk/temp/super8.html
This shows a pair of (large!) gif images of scans from a
Warfedale pamphlet which is also circa 1964.

Units made at other times may well have differed from the above, though.

Don't forget that the Super 8 was mentioned in Gilbert Briggs 1952 book
'Sound Reproduction' so the design was around for a long time!

Yes. :-)

Slainte,

Jim
