- Precision cast and surface treated magnesium cone coupled to a natural rubber surround showing no sign of midrange (edge) resonances.
- Heavy copper rings mounted above and below the T-shaped pole piece reduce non linear and modulation distortion and increase overload margin.
- Extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound refl exion, air fl ow noise and cavity resonance to a minimum.
- A solid copper phase plug enhances the performance of the copper rings and improves heat conduction away from the pole piece.
- Gold plated terminals mounted on a glass fibrereinforced plate to reduce contact resistance and improve reliability.
The frequency responses above show measured free fi eld sound pressure in 0, 30, and 60 degrees angle using a 21L closed box. Input 2.83 VRMS, microphone distance 0.5m, normalized to SPL 1m.The dotted line is a calculated response in infi nite baffl e based on the parameters given for this specifi c driver. The impedance is measured in free air without baffl e using a 2V sine signal.
