Calla Horn Speakers – Blue Grey / Natural – Hardwood 817 A/B

Speakers are shown here for scale with Specimen Single ended Stereo Tube Amp, and with Specimen 14″ Subwoofer + Bluetooth Subwoofer Amp (amps not included – sold separately).

Specimen Hardwood Horns speakers are luxurious. 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.

Years of development have led to the hand craft embodied in these new models. 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 speakers which were featured in the Sonic Arboretum exhibitions.

-Ian Schneller

In terms of physical stature, they fall in between the 36″ Little Horn and the 40″ Liederhorn speakers.  Their more pronounced truncation produces an enhanced spatial sound-stage. In other words, bigger sound in a smaller package.

Custom finishes are available as special order. Call to order custom colors. Custom horn speakers require 3 – 6 month production time.

Calla Horns 

The Calla horn speaker was originally produced for my 2014 show Aero Dynamisms at Packer Schopf Gallery. This installation introduced eight new and unique horn speaker designs in an 8 channel audio system for a sculpture/sound exhibition in collaboration with composer Glenn Kotche.

Their pronounced truncation produces an enhanced spatial sound-stage. In other words, bigger sound in a smaller package.

Considering a special Calla Horns design for the ICA Boston museum shop in conjunction with the museum’s installation of the Sonic Arboretum in 2015, 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.

Design & Construction
All Specimen Horns are entirely handmade at Specimen in Chicago, IL.

The bases are made of premium quality Baltic birch plywood. The horns are made from Italian poplar. 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.

Compatibility and Placement
These Specimen Calla 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 Horn speakers has been described as “holographic” and “etherial” in that the sound seems to be coming from behind the enclosure, making it difficult to identify the sound source. This can evoke the sensation of the instrument being in the room with the listener.
