Динамик СЧ/НЧ PEERLESS HDS PPB 4 8 Ohm 830870. Инструкция на английском языке

HDS PPB
4? Midwoofer
Type Number: 830870
Features:
The new High Definition Sound (HDS) PPB series is the
culmination of Peerless working in close partnership with end
users of Peerless-based audio products. With a deep
understanding of customer requirements and needs, Peerless
developed the proprietary and highly advanced Polypropylene
Black (PPB) cone material used in the HDS PPB Series, creating
a stiff but still dampened cone that remains stable even under the
greatest sound pressures.
