bonjour montage de ce sub entre les sièges arrières dans une EOS à l'emplacement de la trappe à ski avec le coffre comme caisson branché sur un JBL Power(1x160w rms) : bon grave rond , impact au bon moment et manque un peu d'infra mais c'était pas vraiment ce que je recherchais pour mon style de musique !!! donc bien satisfait…….

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.
Bass speaker, 350 WMAX, 4 Ω
25 cm (10 ") bass speaker, pressed diaphragm As a complement to" free air "mounting (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.
