Furthermore the completely smooth design of the WaveGuide reduces diffractions

to an absolute minimum. Finally, the WaveGuide increases treble output in the

lower treble range. Thus the tweeter needs less power for the same SPL. So, power

handling is improved and distortion is reduced.

The 1in tweeter itself features a completely newly designed lightweight silk dome,

carefully coated to achieve the optimum combination of rigidity and internal

dampening.

The magnet features a hollow pole-piece so leaving a chamber behind the dome.

The chamber is critically damped with two types of damping material to avoid

compression behind the dome and tuned to achieve a low resonance frequency at

1kHz (the normal resonance frequency for a tweeter is around 1.5kHz).

The voice-coil former is made of aluminium for optimum heat dispersal. The voice

coil is made of copper-plated aluminium wire. This is because aluminium weighs

less than copper but the copper plating is needed because of its conductive quali-

ties.

All these features when combined allow the diaphragm to move effortlessly and

the result is a very clear and natural, detailed, dynamic and open sound reproduc-

tion all the way to 24kHz (- 3dB).

The absolute focus when developing this tweeter was to enhance its ability to re-

produce the human voice, meaning the lower part of the treble range. Please take

time to listen to the speaker's unusually good ability to convey vocals – we think

you'll appreciate the excellent grip and body it exhibits.

The WaveGuide result in a uniform treble dispersion pattern from 10kHz all

the way down to the critical x-over point at 2kHz and thus secures a seam-

less transition to the mid/woofer – both when listening on and off axis.
