    The larger 10" version of the Concrete Column Speaker offers enhanced performance in a similar DIY package.

    The kit, priced at £6.5.0, includes all necessary components except the concrete pipe, which can be purchased separately for about 12/6 from builders’ merchants.

    This model uses the Super 10/RS/DD driver for extended bass response.

    Specifications include:

    • Driver: Wharfedale Super 10/RS/DD
    • Frequency response: Down to 30 Hz
    • Power handling: 10 watts
    • Impedance: 15 ohms
    • Driver price: £11.13.3 (inc. tax)

    Like its smaller counterpart, this model allows for customization of the concrete pipe enclosure and features a loose weave acoustic material top for improved sound quality.

    Also available as an 8" version.
