On-board Hi-Fi subwoofers for free air use. Reinforced pressed paper membrane, specific suspension with long travel. With reworked magnetic systems for an even greater power, rear pole plate for an exceptionally large displacement capacity.
200 W SubwooferMAX, 4 Ω
20 "(8") bass speaker, pressed diaphragm As a complement to "free air" (without housing) in compact vehicles, remodeled product with lower positioning of polarity elements for greater travel.
With the new parameters, which are translated primarily by a greatly improved Qts, these speakers can now be recommended for closed enclosures or even large bass-reflex speakers.
