The kit, priced at £5.0.0, includes all necessary components except the concrete pipe, which can be purchased separately for about 12/6 from builders merchants. The recommended driver is the Super 8/RS/DD, a highly efficient full-range speaker featuring a ceramic ring magnet and roll surround.

    • Driver: Wharfedale Super 8/RS/DD
    • Frequency response: Down to 40 Hz
    • Power handling: 6 watts
    • Impedance: 15 ohms
    • Driver price: £7.0.0 (inc. tax)

    The concrete column can be customised with various finishes such as paint, wallpaper, or fabric, with the top fitted with loose weave acoustic material for optimal sound dispersion.
