The G.12 Loudspeaker is available with a Permanent Magnet G.12 P.M. or with a Field Coil G.12 D.C. at various prices and configurations as below.
G.12 P.M. (as illustrated) less Transformer £4 16 0 G.12 P.M. with Transformer £5 5 0 So widely has the phenomenal performance of the Rola G.12 become recognised that it is true to say that it is a speaker that sells the set.
Once you have heard the remarkable fidelity of this unit you will be content with no receiver that is not G.12 equipped. You will discover too, that the mere presence of a G.12 in a radio receiver affords proof of its quality, for it would pay no manufacturer to install this unit in a set that was not able to do full justice to such a reproducer. Ask your dealer to demonstrate a Rola G.12 and let your ear confirm our claims.
