A one-inch compression tweeter is driven by a strong neodymium magnet. The result is a driver that guarantees highest resolution and ultra-fast reproduction. The extended reproduction of the highest frequencies gives the rest of tonal range that special quality. With a linear transmission of over 24,000 Hz, the Izumi covers a frequency band that is significantly extended upwards compared to Orfeo and Midas. This allows an improved spatial reproduction of the Izumi. These qualities are supported and significantly enhanced by the use of the ODEON AUDIO birch multiplex horn. The horn functions as a mechanical amplifier that relieves the tweeter and thus contributes decisively to a relaxed sound character while providing highest resolution.

Like the ODEON AUDIO floor standing loudspeakers, the Izumi also uses a downward firing bass reflex system. The downward orientation of the reflex tunnels ensures easier acoustic integration into the living room. Every room has so-called room modes
as a result, strong bass peaks often occur. The downward firing bass reflex system stimulates these room modes much less than conventional solutions in which the reflex tube faces the rear wall. This principle allows the Izumi to be accommodated both horizontally and vertically in shelf units and sideboards without negative bass rezoning effects.

The low-midrange driver is made by the renowned Danish company Scan Speak. Like the tweeter, this driver is a custom-made product outside of normal mass production. By a combination of a handmade and coated cellulose cone with a very fine and flexible rubber surround and fabric centering, this system impresses with an extremely controlled bass and outstanding midrange characteristics unique in this price class. The bass-midrange driver is also refined with a double magnet, which further increases the magnetic force acting on the voice coil that significantly improves the efficiency and sonic characteristics.

The cabinet material is a decisive factor for the sonic properties of low and mid-range reproduction. It is important to avoid disturbing resonances and thus exclude discoloration effects. Plywood has always been the preferred material when it comes to implementing special loudspeaker concepts. The plywood, which consists of many cross-glued individual veneer sheets, is particularly stiff and therefore very resistant of resonance effects.

The Izumi uses a particularly pure oxidation-free copper cabling (OFC) from German production. The multiple mechanical shielding of the tweeter cable virtually eliminates all microphonic effects. To ensure interference-free contact, the Izumi WBT uses Nextgen loudspeaker terminals made of pure, gold-plated copper. Due to their design and low material usage, they suppress eddy current effects that usually occur in plug connections.
