Specimen 2A3 Hi Fi Stereo Tube Amp

The Eremurus horn speaker with yellow bell seen here at Garfield Conservatory in 2014. It stands tallest among the eight unique horn speakers created for the eight channel installation: Aero Dynamisms at Packer Schopf Gallery.

Plumb Horns

Specimen Plumb horns are a natural evolution of my evolving geometries. It occurred to me while contemplating twining vines and creeping foliage, that there is a symbiotic interface between architectonic structure and organic growth patterns. This can be put to good use when a load bearing column cannot easily be eradicated from a new dream loft space. If you cannot beat the enemy, embrace reality and face the music. They are Column Solvers.

Considering this design as an evolution in the horn speaker series featured in the Sonic Arboretum, and as a new generation of my Eremurus horn speaker – the tallest of the eight unique horn speaker prototypes produced for my show Aero Dynamisms at Packer Schopf Gallery, it seemed logical to have the horns integrate well with nature. The design of the Plumb creates a foliage-like effect. The Plumb horns work exceedingly well in any botanical setting. They almost look as if they have grown in place.

Hardwood Series Horn Speakers

This new series of Specimen Horns speakers are luxurious. They are made of Italian Poplar and finished in lacquer. The tight lines and pristine appearance set them apart from my more eco-friendly Horns. Years of development have led to the hand craft embodied in these new models. Natural woodgrain and bold saturated color make these a perfect choice for discriminating audiophiles and interior designers alike. These constructions are so arresting, the sonics so splendid, that I hereby offer them as my flagship models
-Ian Schneller

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.

These XL Plumb horns are made from Italian Poplar wood. The bases are made of premium quality Baltic birch plywood.  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.

First, the hardwood is cut into flats. The edges are then beveled to the perfect angle. After this, the flats are bent into curves that will make up the octagonally fluted horn shape. Assembly is a tricky process that requires two people working together with dexterity and perseverance. The seams are then reinforced with micro fiber filled epoxy and hand sanded inside and out. The assembly is then registered into the flange used to mount the horn to the base, or compression chamber. A natural nitrocellulose finish is then applied to the outside of the horn and an opaque saturated color applied to the bells. This serves as a stunning contrast to the beautiful hardwood exterior.

This meticulous process requires several hundred hours per pair. The result is luxurious.

Form, function and hand work coalesce into a package of stunning beauty and performance.

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.
