GŁOŚNIK NISKOTONOWY ALPHARD PS-10
200 Wat RMS, 400 Wat Max, 8 Ohm, 95 dB 10" 26 cm!
Głęboki dynamiczny bas, który zadowoli nawet najbardziej wymagających fanów niskiego brzmienia. Membrana wykonana z nieimpregnowanej, wzmocnionej celulozy osadzona na sztywnym zawieszeniu. Stalowy kosz nadaje sztywności całej konstrukcji, a jednocześnie nie zwiększa znacząco ciężaru całego głośnika. Głośnik posiada potężny, wentylowany magnes.
Doskonałej jakości głośnik niskotonowy firmy Alphard.
Woofer z papierową membraną prasowaną perforowaną
( nie impregnowaną )na sztywnym zawieszeniu.
Kosz stalowy wzmocniony ,
magnes wentylowany 134mm x 17 mm.
Cewka 2" SPL- 95 dB
