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".

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 a new pricing schedule and the rational for it can be read here.

The Geddes product line currently consists of five models, three are also available in kit form.  This product line is:

bullet

The Abbey 12a

bullet

The Nathan 10a

bullet

The Harper8a

bullet

The 12" Sub 

Polar data program
       Requires MS Internet Explorer

 (LFs simulated on all but Geddes designs - which use near-field data - so others may not be accurate < 200 Hz.)

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.

Please note that prices are per speaker, in US$ and exclude shipping and handling charges

"Baffle" includes custom fit foam plug, waveguide, compression driver mounting plate and hardware.  A set of cabinet drawings and a schematic are included.  Videos of assembly will be made available. It is required that the front baffle edges be routed after assembly of the enclosure.  This requires a router and a 3/4 to 1-1/4" bit depending on model and ability.  The larger the radius the better, but a Harper is limited to 1" and Nathans and Abbeys to 1-1/4".  GedLee can assemble the basic enclosure and route these edges if required for an additional fee.

"Drivers" are the drivers appropriate for the design.

"Crossover" contains all electronic parts, but does not include a CLD back panel for mounting the parts.

The speakers should be glued together using  http://www.innovative-polymers.com/images/products/ie-3065.pdf

Fully assembled speakers are FOB my workshop.  Packing for shipping and shipping costs are extra.  These speakers might not be shipped as fully assembled units depending on destination.  They will be finished and tested but then disassembled for shipping as appropriate.

Assembled products come in standard black, white or red (other colors and finishes available on request and priced accordingly).

A fully refundable deposit of 1/2 total purchase must be made to get in the delivery queue, which also fixes the price - please use www.Paypal.com and account - sales@gedlee.com.
Deposit is not refundable once the order build has been started.

Changes to content can be made at the discretion of the manufacturer and options can be eliminated at any time.
