Динамик СЧ SCANSPEAK 12MU/8731T00. Инструкция на английском языке

MIDRANGE                                                 12MU/8731T00
The Illuminator midranges and midwoofers are in every aspect unusual designs with
the open construction, the extremely long linear excursion and patented under-hung
SD-3 (Symmetrical Drive) neodymium motor system, which due to copper caps and its
construction ensures very low distortion, adding the unique patented cones, low-loss
linear suspension the result is: “The Very Best Money Can Buy”!
