Austrian loudspeaker manufacturer Trenner & Friedl has a thing for coaxial drivers. They're used in at least three of the company's eight loudspeaker models, including the diminutive Sun bookshelf speaker and the large floorstanding Taliesin. In these models, T&F eschew more conventional stacked drivers for a putatively time-aligned, wide-frequency range coaxial design.

"The crying rain like a trumpet sang
And asked for no applause."—Bob Dylan, "Lay Down Your Weary Tune"

Between the strange, nattering voices, the radio emitted a sharp hissing sound. That's my first memory of human voices coming from a little box.
