Geddes Loudspeakers

The Geddes line of loudspeakers is the product of years of intensive research into loudspeakers, room acoustics, and psychoacoustics.  This research has led to a rather unique approach to an optimum sound playback system for a small room. The speakers shown here represent the current state-of-the-art in loudspeaker design using the highly acclaimed waveguides that have been developed by Dr. Geddes over more than thirty years.  A white paper is available that highlights Dr. Geddes approach to systems design. This approach is based on his years of research into the problems of audio playback in small rooms and this paper defines the design principles that go into each of Geddes products.  Dr. Geddes has added a comprehensive paper on directivity.  The need for this paper was highlighted by the number of questions that are received about directivity - What is it? What is good or bad directivity? There is also a paper on "What is a Waveguide". For those curious about Geddes "Multiple Sub" technique view this Presentation or the PowerPoint The multiple sub setup is supplied free to any customer who buys two or more subs.  The setup is now available as a stand alone service.  The fee is $200 for Geddes Speakers (non-sub) owners (of record) and $400 for non-owners. The manual for doing this is available here. Several reviews of Geddes Loudspeakers are available. These reviews testify to the correctness of Dr. Geddes's unique approach.  It should be noted that these aren't select reviews, taken from a variety of various reviews, these are all of the reviews that have been received. None have been left out. There is now an option for using an active filter (supplied).  The current pricing is the same for active or passive for the Abbey and a small differential for the others.  The active crossover is supplied by a pre-programmed MiniDSP module. The price has been reduced for the Nathan 10C.

Which model to buy? The Summa Cum Laude offered maximum performance but at a considerably higher cost, volume and weight (currently unavailable); the Abbey is less expensive, smaller and much lighter, but gives up very little performance; the Nathan is a substantial performer in a very reasonable size, weight, and cost, and finally the Harper is small, lightweight, and inexpensive and yet maintains much of the superior quality of its heftier siblings.
