Concrete T L Speaker

 

When presented with the opportunity to compete in the PPC Imaginarium competition, designers Martin Bolton and Craig Tyndall joined forces to create the Concrete T L Speaker.

 

Their design, which has a shape reminiscent of an indigenous African trumpet, was made using a mesh of steel and rebar and a mixture of sand and cement to create the desired shape applied to a much smaller product using the same principles of thin shell organic forms. The speaker was then moulded using a non-aggregate mixture of cement and sand and a thin steal fibre to mitigate the formation of surface cracks due to shrinkage and allow for a gloss finish. The Kudu horn shaped speaker carries the sound outward and towards its audience. The acoustic properties afford it to be a superior medium for speaker construction due to its mass and dampening properties.

 

“We were inspired by the works of Heinz Isler and Felix Candala who are renowned for pushing the limits of thin shell concrete structures.” the duo said about their triumph transforming concrete from “an everyday construction material into a highly aesthetic, functional and superior audible product”.

 

Martin and Craig were announced as the overall winners at the PPC Imaginarium Awards last week in Cape Town. The awards were judged by a jury of leading industry talents including architects Mokena Makeka and Profesor Ora Joubert; industrial designers Adriaan Hugo and Katy Taplin of Dokter and Misses; fashion designers David Tlale and Tiaan Nagel; jewellers Verna Jooste and Cari-Mari Wilsenach; artists Dianne Victor, Kay Potts and Ledelle Moe; and filmmakers Wessel van Huysteen and Beathur Mgoza Baker. In the end, the Concrete T L Speaker won the judges over for its elegantly minimal reinterpretation of an African tradition into a contemporary design solution.

 

PPC Imaginarium director and architect Daniel van der Merwe commented: “The winning piece is not only an original approach to the functional dictates of a speaker design, but executes it in a uniquely sculptural way. This is a demonstration of the versatility of concrete as product design.”

 

The PPC Imaginarium exhibition will be open to the public from 06 – 28 March 2015 at Youngblood Foundation Gallery, Bree St, Cape Town.
