David has completed a build of Adam's DIY 3-Way HiVi Tower Speaker Project. Each three-way tower loudspeakers uses one HiVi F8 woofer, two HiVi F5 mid-woofers and a HiVi RT1C-A Planar Isodynamic Tweeter. The speaker is the same as the original build with the exception that a HiVi Research RT1C-A tweeter is used in place of the HiVi SD1.1A tweeter.
