Jodra 'The Enchanter', model G cone speaker
Baker-Smith Co., Inc. and Jodra Mfg. Co. both produced the same line-up of speakers, so I am grouping the Enchanter and Frusto speakers here together. One company probably superseded the other.

Bristol Audiophone Senior horn speaker
Largest of the three horn speakers manufactured by Bristol, an impedance matching transformer is hidden in the metal base. Input resistance to this transformer is only 240 ohms. The driver has an armature driven diaphragm for better low frequency response than was typical for horn speakers. A knurled coupler can be unscrewed to remove the metal bell from the driver. The bell/driver assembly swivels on the base. The speaker measures 21-1/2 inches tall, bell diameter is 15-3/8 inches, and the color was advertised as 'dull gold bronze'.
