Speaker Builder: The Pyramids By Rudiger Geppinger

In this classic speaker from Speaker Builder, the author proposes a complete project of a speaker design with a pyramid-shaped cabinet. The fact that its nonparallel walls minimize standing-wave effects, and the slanted front improves the time adjustment of the dri­vers, added by the fact that the front is wide enough at the base to accommodate a larger woofer, and narrow at the top, where the tweeter is located, were the fundamental considerations. This article was originally published in Speaker Builder magazine, March 1998.

For this review, Ken Bird details his experience in building a set of speakers from Swans Speakers Kits, part of a new catalog created by HiVi Acoustics and Swan Speakers (HiVi's consumer brand), and that so far includes two kits: a two-way bookshelf design, the DIY 2.2A, and the slightly larger three-way design, the DIY 3.1A, the model sent to audioXpress. Both models incorporate HiVi drivers. This article was originally published in audioXpress, August 2019.
