Two-Way Koaxial Speakers


  1. About
  2. Design Goals


This project is in the very early design stages. I'm currently looking around which speaker chassis to use...

Design Goals

  • Full range living room speaker for normal listening levels in flats (not exceedingly loud).
  • Koaxial speaker design for coherent sound reproduction. Likely candidates include the Thiel SCS range of speakers (currently too expensive for me if I cannot find an inexpensive used pair) and the Audison APX 6.5 coax chassis (Way cheaper and pretty promising from what I read).
  • Wide baffle (~50-60cm) with large rounded corners (r>5cm) for minimizing baffle step problems and more even off-axis frequency response.
  • Closed box design. In my experience easier to set up in a room than ported designs and the bass response is easily accounted for by some low shelf eq boost.
  • Actively crossed over and equalized (see above) with Pulseaudio Crossover Rack and multi-amped with modern class-D amps.
