IsoFlare™

IsoFlare technology is a point source system where the bass/midrange driver and the tweeter driver share a common center. This means that the sound waves appear to come from a single point in space. This enables isotropic (uniform) sound propagation and constant directivity that follows the shape of the driver diaphragm.

A key benefit is excellent stereo imaging, even outside the ideal listening position. By temporally aligning the sound waves produced by tweeters and woofers, a more coherent, natural sound is produced that resembles natural hearing. In addition, a point source system maintains phase consistency across the entire frequency range, which better preserves the harmonic structure of musical instruments and creates a wider listening zone (sweet spot) for the listener.

Traditional speakers have separate tweeters and woofers, often positioned differently on the speaker front. This allows sound waves of different frequencies to reach the listener at different times and from different directions, which can result in a less coherent and natural sound. It can also affect imaging and spatial representation, requiring more precise placement of the speakers in the room. IsoFlare aims to avoid these problems.

The IsoFlare driver is equipped with a number of technical details. These include a rigid cast aluminum chassis to eliminate unwanted vibrations and a multi-fiber paper diaphragm for natural sound reproduction and good transient response. The tweeter consists of a very rigid magnesium or titanium diaphragm to achieve a smooth and extended reproduction. The unique shape of the tweeter's waveguide also delivers a flat frequency response and prevents internal reflections.

By sharing a common source of sound waves, the IsoFlare driver creates a very accurate spatial image. The ability to radiate sound "isotropically" allows for even sound distribution throughout the room and a wider, less restricted sweet spot, making music sound more authentic and three-dimensional.

IsoFlare technology is now used across all Fyne Audio product ranges, from the high-end F1 and Vintage series to the more affordable ranges such as the new entry-level FE series. So it is available across a wide range of prices and in a variety of form factors, including bookshelf and floorstanding speakers.

The alignment of the drivers to a common point and the special waveguide design enable even dispersion of the sound. The isotropic radiation ensures that the sound quality remains high even outside the optimal listening position, so that a coherent sound is maintained even when moving around the room.

Choosing between a point source design like the IsoFlare and traditional speakers is often a matter of personal preference. While IsoFlare offers a number of advantages in terms of coherence, spatial imaging and versatility, traditional designs can also produce good results depending on individual preferences or spatial conditions. FYNE Audio prefers IsoFlare technology to create the most natural and immersive listening experience possible.
