Description:
10 cm (4") High-End low-midrange driver featuring a diaphragm cone made of pure titanium. The carefully designed cone combines with the shape and material of the surround and the adhesives to avoid cone resonance. The shape of the basket with its large aperture and rear-ventilated damper coupled with the open voice coil with its phase plug produce the lowest possible mechanical losses and produce a correspondingly high mechanical Qfactor.
As a result of the construction using double magnets the TI 100 - 8 Ohm is also magnetically compensated. The TI 100 - 8 Ohm is ideal as a mid-bass unit in smaller high end shelf speakers or as a mid-range unit in high-end multi-way Speakers.
