Hi All,

I just came across this Rola speaker amongst my stuff.
It's 10" x 2-5/8"

Can anyone offer any info regarding it's age and where it may have been used originally?

Many thanks.

The speaker is a Rola type 10-3G (Fluxmaster Model G) and dates from the late 1950’s to the early 1970’s. They were typically used in tight spaces like compact TV receivers. (Note the model number indicates the dimensions in inches)

I have one of these mounted in a purpose built black plastic enclosure, for under dash car mounting.
May have been a Ferris car radio product.

I've seen them mounted in standard equipment rack panels as monitoring speakers in PMG/Telecom exchanges and radio relay stations.

I seem to recall seeing those oddly-shaped speakers in televisions ages ago, I'd regard it as a more extreme example of an elliptical speaker.

That ad gives the address of Rola as Caltex House, Kent St. As it happens, Kent St is rather long, any idea where Caltex House was?

I recall it well. My mother liked to use the public parking station on the lower levels whenever she brought us kids into the city.

I suspect Rola developed that speaker for Admiral. The Admiral 21" 110 degree models released in 1958 are the earliest examples I can recall.

They were also used as midrange driver in Philco electrostatic speakers (late fifties.)
