About Us: Jonny Anderson

Jonny Anderson Natural Stone Speakers

Jonny began a stonemasonry apprenticeship in 1984 with the Cambridge based firm Rattee and Kett. In the 10yrs with them he worked on Kings College Chapel, Trinity Gate and Westminster Abbey. Moving to Gloucestershire in the 90s he became Freelance and began to develop his carving skills.
Favouring the Abstract, Jonny combined his passions for form and music by producing his first pair of stone speakers in 1998. Since building these prototypes Jonny has steadily refined the process and now handcrafts these uniquely shaped speakers after hollowing out solid blocks of stone. Each pair is tuned to give a flat response with great stereo imaging.

Training

Jonny Anderson Natural Stone Speakers

In 1998 Jonny teamed up with ROCKWORX to run a small stonecarving workshop at Glastonbury Festival and due to the initial success this has now developed into a much larger workshop with a solar powered sound system powering Anderson Speakers creating a lively and vibrant atmosphere for people to enjoy.

In 2008 Jonny was asked by Woodchester Mansion to run training courses for the Building Craft College students and Get Into courses for the Princes Trust. This has now extended to Bath College students and The Princes Foundation Building Craft Apprentices. He also Assesses for Banker Masonry and Heritage Stonework qualifications through the CITB.

Since 2010 Jonny has been heavily involved with training at Dumfries House for both The Princes Foundation and The Princes Trust.

What our Clients Say

These speakers not only provide high quality sound but look amazing and are a focal point in any room

Colin Kingsnorth

These beautiful bespoke stone speakers by Anderson recently caught our eye. We think the shapely speakers would look great in one of our high-end residential projects.

Matt Tillman, Tillman Domotics

Jonny’s speakers are a pleasure to have around as stand alone sculptures, even more of a pleasure when making their sweet music.

Jesse Carrington Trainspotters Ltd

If you are looking at this sight you are looking at pieces of art which work and look fantastic, I think the word is Masterpiece. Whilst at Glastonbury three years ago we came across Jonny the Stone,as he is known with a crowd of people all stone carving to music. I was intrigued by two things the stone carving and the sound which was emitting from two huge stone speakers, the sound reproduction was excellent.

FAQs

A choice of Limestone, Marble, Slate and Sandstone is available from which each unique pair of speakers can be made. The stone is sourced from a number of quarries both local and further afield and, whenever possible, reclamation yards .
Stone is an excellent material to use as a cabinet for the reproduction of sound not only because of its aesthetic natural beauty but because it is dense, heavy and therefore has a low resonance coefficient. This means that less resonance in the cabinet equals a clearer signal from the speakers.
A combination of ATC and SEAS drivers are used depending on the required configuration and size of speaker required. The electronic crossovers are then tailor made for each for each pair. The speakers are then sine wave tested and Port tuned to ensure high quality audio output.
