Harmony Through Symbiosis 3-way Horn Loudspeaker

With the introduction of the Helix model, Odeon has combined our latest technology in a size able to look right in all living rooms big and small. All this combined in the smallest ODEON AUDIO three-way horn loudspeaker. The Helix is the result of the development of a completely new generation of three-way loudspeakers. After 1992 and 2000 the Helix marks the beginning of a new era. The Helix is a perfect match for all kind of high-quality solid state and tube amplifiers up to low power triodes like 300B. The Helix can be used in a small listening room as well as in a large living room with convincing outstanding midrange characteristics, finest resolution, as well as a seamless, homogeneous reproduction. The new housing design provides for improved phase alignment compared to the predecessor models, since all systems are now positioned exactly on one axis due to the changed proportions of the cabinet. The two-part cabinets of the Odeon Helix are made of a material mix of multiplex and a special medium density fibreboard (MDF). The cabinet materials used are decisive factors for the sonic properties of low and mid-range reproduction. It is important to avoid disturbing resonances and thus exclude discoloration effects.
Compared to the previous model (Odeon No. 28/SE), the new shape of the bass cabinet allowed more volume to be accommodated in the cabinet and thus improved bass performance. In addition, the new asymmetrical cabinet design prevents standing waves. This allows the use of less damping material and thus maximum efficiency. Like all ODEON AUDIO floorstanding loudspeakers, the Helix works with a downfire bass reflex system in which the bass reflex tunnel of the Helix points downwards towards the base plate of the loudspeaker. The downward orientation of the reflex tunnel makes for easier integration into the living room. Every room has acoustic characteristics, so-called room modes. As a result, strong peaks in the bass range often occur. The downfire bass-reflex system stimulates these room modes much less than conventional solutions in which the reflex tube faces the rear wall. This results in a much clearer and faster bass reproduction.
