Visaton BZ 130 4 Ω
13 cm (5") low-midrange system with a very strong magnetic drive and mounted in a Euro standard basket. The connection terminals are gold plated 4.8 mm and 6.3 mm soldering lugs. Coloration free midrange and high efficiency. Car specific installation is possible, provided that the mounting depth of the large magnet has been considered.
