Динамик широкополосный PEERLESS 2.5 4 Ohm 830985. Инструкция на английском языке

2?? Full Range
Type Number: 830985
Features:
Peerless full range drivers set the standard for quality audio in
products including flat panel televisions and sound bars, MP3 and
cell phone docking stations, and multimedia PCs. With their high
power handling, smooth, even dispersion and low distortion, the
Peerless full range drivers can be paired with the Tymphany
LAT250 for great bass performance.
Features include: A Neodymium motor structure and double-
venting system that helps keep dynamic range intact, as the
transducer can handle more power and dissipate excess heat
efficiently. An anodized aluminum dome provides superior sound
dispersion and off-axis response. A semi-progressive surround
reduces distortion, especially at high output through long
excursion. The drivers’ direct connected dome dust cap
(connected to the magnet system voice coil) improves dispersion
at high frequencies, providing superior sound on the high notes.
The inserted cupper cap on the pole piece ensures control the
system impedance, thereby extending the upper frequency
range.
