Selenium D405trio Proline Compression Driver

This item is brand-new, factory sealed.

Compression driver compact size, has a high
sensitivity and low distortion covering an average response
frequencies. Can be used in cases of sound reinforcement (pa), monitors
and cases of return (and side-fill stage). This performance is achieved by
excellent combination of its components:
the aluminum lid is injected thereby contributing to a better
decalor dissipation of the voice coil, with a finish machining
diamond tool (diamond) and varnished.
the phenolic dome type diaphragm ensures efficiency and durability,
even when exposed to large displacements due to high powers.
the acoustic transformer "phase plug" is injected with aluminum
several openings optimized by minimizing phase cancellation, has
finish machining diamond tool (diamond) and
varnished.
the magnetic assembly has high-flow inside a ring
aluminum short circuit, which prevents the modulation of magnetic field
whose rapid changes and intense signal invariably cause
distortions. Moreover, the gap has set inside a fluid
magnetic (ferrosound ), which provides better balance and excellent
heat dissipation of the coil.
the voice coil is made with high temperature resistant wire and
rolled into a kapton , obtaining a large set of
stability and strength.
the driver has the mouth of 50 mm (2 ") diameter allowing
direct coupling to the horns of the same diameter throat.
the mobile set (repair) has a perfect self-centering
is also easy to exchange in case of any defect.
it has compact dimensions, easy installation in boxes
reduced size.
