A vintage Tannoy 12 inch Red Monitor Dual Concentric Loudspeaker Type LSU / HF / 12.L with Tannoy Cross-Over Unit Dual Concentric L.S. Type LSU / HF / 12 L 15 Ohm Impedance.I believe the speaker dates to around 1960 and I can confirm that I have had the speaker working. It was originally in an extremely large and heavy wooden casing and as you can see it has been dismantled for packing and posting. International Bidders please note this is a heavy item and postage includes courier delivery with tracking. Please feel free to ask any questions. Thanks for your interest, Amanda.
