8LW30

This 8" 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 8LW30 incorporates a 2.5" voice coil made with high quality materials: aluminium wire with high temperature bonding strength and fiber glass former. The 8LW30 is highly recommended for those woofer applications that require a light and small loudspeaker with excellent technical specifications.

Key features:
  • Ultra light loudspeaker (2.35 kg. 5.17 lb.)
  • High power handling (250 w AES)
  • 2.5" (62.4 mm.) aluminium voice coil
  • High sensitivity: 96 dB
  • Superior performance neodymium magnet system
  • Half the weight than a conventional ferrite model
  • Large Xmax: 4.5 mm.
  • Extra vented magnetic structure
  • Designed for extremely compact woofer applications
