BL15-400X

Not every player wants a super-clean, high-fidelity bass sound. Characterised by an extended low end and greater linear excursion, Green Label speakers push out every note with a rich, warm tone and a powerful low-end thump.

Available with Ferrite or Neodymium magnets, Green Label speakers are primed for high-powered rock performances, where a full-bodied, warm, defined tone is essential.
