I thought IIILZ was a cabinet designation not a driver model?

No, not quite as the designation IIILZ applied to both a cabinet and a driver, so your confusion is understandable.

The Tannoy IIILZ speaker (I believe the latest version was the Mk. II) was an infinite baffle forward facing design using a Monitor Gold IIILZ dual concentric unit. It measured 14" x 10.75" x 23.25"

The Monitor Gold IIILZ speaker chassis was a 12" dual concentric driver with a molded fibre cone and a plastic impregnated surround. The gap flux for the LF section was 10,000 Gauss and for the HF section was 15,000 Gauss. It had a handling capacity of 10 watts, voice coil impedance of 15Ohm and frequency response 23Hz - 20KHz.

When used in the IIILZ enclosure the response was 30Hz -20KHz. The crossover used had a crossover frequency of 1KHz.




Worden used the IILZ chassis (and crossover network) and fitted it to his own horn cabinets.

Frank Worden was an independant audio maverick/free-thinking designer, active during the '50s and '60s. Worden was probably most famous for his articulated pickup arm. http://soundup.ru/index.php?option=com_content&view=article&id=992:worden-articulated-1962-wood-tonearm&catid=20:tonearms&directory=1 This had dynamic balancing and was an early attempt, though not the first, for a pivoted arm to achieve zero tracking error across the record.

I think I saw Worden at one of the first audio shows I attended. From memory he looked a bit like the Professor in the Rupert books!

Worden loudspeakers were as far as I can vaguely recollect, manufactured in the fifties and sixties in the UK and I believe they used a variety of drivers from different manufacturers. The Worden IIILZ horn cabinet is not one I've seen before. Guessing at it's age, I'd suppose this to be the Tannoy Red version of the IIILZ with the round chassis flange.

As has been stated, the IIILZ designation applied to the cabinet system and the driver on it's own, I know because I bought several pairs (the Monitor Gold version) new in the seventies and can recall the IIILZ labels on the cabinets and the markings on the drivers.

I liked the IIILZ, but did not find them as good as the 12" Monitor Gold or the HPD295A.

I believe the IIILZ is a 10" driver.

I believe the IIILZ is a 10" driver.

Not according to my 1971 edition of the Hi-Fi Yearbook.

However surfing some Tannoy enthusiast websites, there are references to a 10" version. I suspect Tannoy were a little inconsistent in their nomenclature. :scratch:

I believe that the IIILZ was a 10" unit, but some versions had a big flange so that they could be fitted to an baffle that was cut for a 12" unit. Never owned IIILZ's so not absolutely sure.

Do have some HPD315's that I quite like.

The IIILZ was the 10" driver equivalent in the Tannoy Red and Gold driver line-up with the 12" next up the range. The quartic (Tannoy's own term)chassis of the later IIILZ was virtually the same as the one used on the following HPD295 8 and HPD295A. The earlier versions did have a wide circular chassis flange, but the same sized cone (approx 8" across the driven area, not including surround). The bass voice coil on the IIILZ was wider than that used on the 12" units for some reason.

I have just done a trawl of references to the Tannoy IIILZ and it definitely is a 10" design. Would seem the entry in the 1971 HiFi Yearbook stating the size as being 12" is incorrect.
