The Three Sad Bastards

Meet the team

Aris, John and Trevor have been involved in the design, build and test of the Keystone, Bedrock, Ochto and Cardia components from the initial concept stage. They continually provide feedback and suggestions on the current state and evolution of each project.

A brief history

The idea to design and build a loudspeaker was initially discussed in the Three Sad Bastards Podcast series where they irreverently considered what would be involved in designing and building a (good) loudspeaker.

Light-hearted conversation soon transformed into obsession as they started looking deeper into what would be involved.

As luck would have it, an opportunity (6 months gardening leave) provided the time and funding towards feeding the obsession, and after 6 months of full-time, dedicated research, learning, design and build, the Keystone, Bedrock, Ochto and Cardia became real.

Using CAD, CNC, and DSP we were able to iterate loudspeaker designs quickly, backed by measurements, theory and extensive listening sessions.

Along the way we designed and built a small 2-way (the Stellar Bookshelf) which is an outstanding value small speaker with amazing imaging and tight bass.

Listening setup at home of the Keystone prototype (outer) speakers, and the Ochto amplifier proof of concept (middle). Also shown is a small 2 way (inner) that is under development.

Where we are today

cexe audio was established to provide good quality, high value audiophile-grade loudspeakers for a reasonable cost.

Projects are underpinned by a modern, practical and science-based philosophy.

  • No analogue cross-overs
  • No exotic metal wiring
  • No tubes/valves
  • No exotic/expensive drivers
  • No low-cost/performance drivers
  • No hard to get components 

The design principles employed:

  • Digital / active cross-overs
  • Linear-phase FIR
  • Time alignment of drivers
  • Build process must be viable using easy to get materials and tools
  • Products should be able to be easily fixed if something goes wrong
  • Firmware or configuration easily upgrade

Finally each projects aims to provide a design that can be implemented as is, or as a foundation for a derivative project.

  • Designs that can be used to build the project
  • Detail to enable customisation or changes
