Compression Selenium D220TI OMF (8Ohm)
[D220TI OMF-8] Avis/Critiques Produit vendu à l'unité, prix affiché pour une pièce.
High quality compression driver with dome diaphragm in pure titanium, offers high efficiency and low distortion over the medium and high frequencies band.
It can be successfully used in studio monitors, stage boxes and sound reinforcement in small rooms, where a high performance is requested.
This performance results from the proper combination of the components.
Diaphragm type dome in pure, rigid, light and extremely thin titanium (0.025 mm). To avoid stress and distortion, the suspension has a special design.
Injected phase plug in engineering plastic, optimized to eliminate undesirable phase cancellations.
Magnetic assembly that concentrates flux in the gap, optimized using FEA(Finite Element Analysis).
Voice coil manufactured in CCAW (Copper Clad Aluminium Wire), Kapton former, assures great stability and thermal resistance.
The moving assembly has a perfect auto-centering characteristic that turns replacement in an easy task.
