We know the higher the frequency the more likely beaming like a torch can occur. To overcome this we moved beyond the conventional forward firing super tweeter. The SuperTrax’s omnidirectional design radiates energy through 360 degrees, enveloping you in a sphere of coherent sound. This is made possible by our patented SuperTrax tractrix radiator with its revolutionary approach to sound dispersion.
No Frequency Beaming -Forward firing devices will have a very narrow dispersion at these ultrasonic frequencies, which means they will beam like a torch. The 360 degree design of the SuperTrax means there will be no beaming but instead an immersive sound stage.
Even Response At Any Angle - In a typical room, a high proportion of sound perceived by the human ear is reflection generated by the off axis response of the speaker. Therefore any enhancement with a super tweeter is best served by an omnidirectional device with even response at any angle, placed at the acoustic centre of the main driver.
Patented Tractrix profile - Known to maintain a 90 degree angle at each intersection of the expanding wavefront. The plane acoustic wavefront generated by the dome is translated into a spherical wavefront into the room, where it meets the diffuser.
Ability to time Align - The addition of a SuperTrax, when time aligned to the acoustic centre of the IsoFlare, will reduce the high frequency phase error by moving the low pass roll off point much higher.
Revealing Harmonic Detail - Every loudspeaker or audio device exhibits a low pass filter function and consequently acts as a frequency independent time delay in the pass band, otherwise known as a linear phase response.
To reduce the low frequency phase error, we would add a subwoofer, which does more than just add bass. It is this reduction of phase error that is one of the main benefits of a well integrated subwoofer. Music with no apparent bass content will sound more natural when this error is removed.
Likewise, the addition of a super tweeter, time aligned to the acoustic centre of the IsoFlare, will reduce the high frequency phase error by moving the low pass roll off point much higher. So even if we ignore for now the perception of sound above 20kHz, the addition of a super tweeter will better preserve the harmonic relationship between instruments and is apparent down to low frequencies. This is a very important fact which is not intuitive.
A Spectrum Beyond Hearing - Research reveals that musical instruments emit energy up to 50kHz and beyond frequencies once thought to be beyond our perception. Yet, research has shown that these ultrasonic tones do influence our auditory experience, even if they’re not directly audible. The SuperTrax captures this spectrum, ensuring you’re not just listening to music-you’re perceiving it.
The Revolution of TPCD - At the heart of the SuperTrax lies the Thin Ply Carbon Diaphragm, a new type of dome material, allowing frequencies to reach up to 60kHz, before introducing a controlled break-up of sound. This enables a linear and extended frequency response without distortion, thus delivering sound with high accuracy as the artist intended.
Grounding Terminal - Includes an extra earth terminal that grounds the driver chassis to prevent radio frequency interference effects from masking fine detail.
HF Adjustment - HF output controls are integrated on top of the cabinet, offering user adjustment of high frequency energy giving you customisation to your preferred sound.

But I can't hear above 20kHz, what's the point?
Musical instruments produce energy well above the generally considered limit of human hearing. Research has shown that we are capable of responding to this energy, justifying the addition of a super tweeter where wide bandwidth sources are used.
But surely this goes against the IsoFlare point source design theory?
For a super tweeter to work correctly in the time domain, it has to be positioned backwards on the cabinet, to match the acoustic source of the main driver. Positioning the super tweeter at the front of the cabinet, as is often seen, is not ideal, although it could be argued that with a discrete non point source loudspeaker this is of even less consequence.
But Red Book CD standard only goes to 22kHz, how can this help?
There is no phase errors in the audio pass band of a Red book CD due to the nature of the digital filtering used. However the addition of a SuperTrax preserves this phase information even though there is no ultra sonic information present in the source.
