Haut-parleur Beyma 12LW30/N
[12LW30N-8] Avis/Critiques

This 12” bass loudspeaker has been designed to achieve a very light loudspeaker with superior technical specifications. Thus, the magnetic system incorporates a high energy neodymium magnet, reducing the total mass of the unit to less than 50% of a conventional ferrite model. Moreover, the heat dissipation has been improved with the use of extra-cooling. The 12LW30/N incorporates a 3” voice coil made with high quality materials: round copper wire with high temperature bonding strength and polyimide former. The 12LW30/N is highly recommended for those woofer applications that require a light and small loudspeaker with excellent technical specifications.
