Focal ISUB twin passive underseat subwoofers. Nearly new, I fitted them under the front seats of our Caravelle, but then needed to use the space for leisure batteries. Complete in original box & packaging, with the velcro fixing strips. Given the relatively small size (26x24x8 cm) Focal have done a brilliant job ofc making these sound good; installation is very easy too. 2ohm, 83 dB sensitivity. Paid carriage or collection (GU10 area) is welcome.
