Phase Plugs
We 5 sizes of bullet-shaped phase plugs for popular full-range speakers. Many loudspeakers are improved by removing the dustcap and replacing with phase plugs. Also of use to recover drivers from dustcap damage.

Flat-paks & Bespoke Speaker Enclosures

We have a number of standard flat-pak speaker kits. Frugel-Horn Mk3 are our most popular.

Bespoke builds of finished loudpeakers can also be ordered. These are usually restricted to our designs.

Fine art builds of solid wood are available on a limited basis. A solid western red cedar flat-pak of the µFonkenSET is a fallout from this work.

Vintage HiFi

This business got its start with recycling vintage drivers & other vintage hifi. We no longer do this on a regular basis, but we still have a lot of inventory. Much of this is now available for free for those who would like to get into the hobby & have no budget, andcan drop by the mountain.

An associate,
Barry Plewes, has a stock of of vintage electronics, speakers, sources, and other goodies. Our goal is to start a renaisance room as an outlet for these If you can't wait contact Barry.
