Singleton Horn Speaker 305
The Singleton Horn Speaker 305 utilizes re-cycled newsprint and has a heavy-duty, long excursion cone that delivers outstanding bass for a 3″ driver. A full range driver is rear loaded with a horn shape to match the acoustic impedance of the air in the compression chamber with the air in the listening room. There is no crossover distortion. The base is made of premium Baltic Birch plywood.
This Singleton Horn Speaker – Dark Green 305 is an original prototype introduced among the eight unique horn speaker designs for my show Aero Dynamisms at Packer Schopf Gallery, in 2014. This sculpture/sound exhibition featured my 8 channel tube audio and speaker system in collaboration with composer Glenn Kotche.
Compatibility and Placement
All Specimen Horn speakers can be paired with my hi-fi tube amplifiers for a beautiful sonic symbiosis. Or they can be paired with virtually any other system and achieve excellent results. They are also perfect for home/office theater use.
These speakers are designed to work well elevated as a typical bookshelf speaker, out in the open, or even placed on the ground to achieve a more spatially expansive installation, as in the Sonic Arboretum exhibitions. The sound of Specimen Horns has been described as “holographic” in that the sound seems to be coming from behind the enclosure.
Design & Construction
All Specimen Horn speakers are entirely handmade at Specimen in Chicago, IL.
All horn speakers are made from recycled newsprint, dryer lint, and shellac, making them by far the most eco-friendly Specimens to date. The bases are made of premium quality Baltic Birch plywood. Dryer lint is one of earth’s greatest squandered resources and we are now putting it to use. It has incredible strength from all the interlocking fibers.
Each horn is unique and embodies a variety of markings that result from the construction and finishing process. This raw and organic finish lends a unique patina to each horn.
Considering this design for Aero Dynamisms, as a natural evolution of my geometries it seemed logical to have the horns integrate well with nature. These materials accomplish this as they create their own foliage-like effect. They work exceedingly well in any botanical setting. They almost look as if they have grown in place.
Museum Legacy
The Specimen Leiderhorns, Hornlings and the smaller Hornlets horn speakers were first created for the Sonic Arboretum, a collaborative project between Ian Schneller and composer/violinist Andrew Bird. The Sonic Arboretum installation had its debut at New York’s Guggenheim Museum in 2010 and in 2011 at the Museum of Contemporary Art Chicago. The installation included a collection of 76 different Specimen horn speakers and Specimen Custom Tube Amplifiers. The Sonic Arboretum exhibited again at the International Contemporary Art Museum, ICA Boston in 2015, where the specially designed Specimen ICA Calla Horns System made its debut.
