Beyma 12 P 1000/ND Neodymium

12P1000/Nd

This model is the result of an extensive and intense research of every single constituent part of an electro-dynamic loudspeaker, rethinking the basics and taking care of every detail, to withstand the extreme power conditions it has been designed to work in. All this investigation is reflected in the new and innovative technologies developed by Beyma and applied in this new transducer.

Key Features:

• Real 900 W AES power handling
• Sensitivity: 96 dB @ 2.83V
• 4" duo technology voice coil
• Forced air convection circuit for low power compression
• Extended controlled displacement: Xmax ± 8 mm.
• Massive mechanical displacement capability: 52 mm p-p

DUO TECHNOLOGY 4 VOICE COIL:
Laminated former combining two different advanced technology materials to enhance the voice coil life.
Voice coil winding coiled over the two faces of the former.
Double insulation paper (inner and outer) for optimum force transmission.
Superficial treatment of the voice coil winding to provide further protection to the voice coil wire.

MOVING ASSEMBLY:
High stiffness weather resistant paper cone.
Beyma Double Conex Spider technology (D.C.S.): the conex is a fireproof material that insures the preservation of the spider mechanical properties under extreme power
conditions.
Beyma Mechanical Mirror Suspension System (M.M.S.S.): the diaphragm surround and the double spider have been carefully designed with the assistance of Finite Element calculations in order to match coherently, enabling long and controlled cone displacements.

HEAT DISSIPATION:
Low power compression due to the use of a forced convection mechanism.
This design has been optimized with the extensive use of miniature high temperature probes and real-time temperature acquisition systems, together with a thermographic camera to obtain real images of the heat distribution in the voice coil and forced convection effects.

UNDER-POLE NEODYMIUM MAGNET TOPOLOGY:
F.E.A. optimized under-pole magnet topology. This geometry maximizes the flux density in the air-gap and completely eliminate the leakage magnetic field, avoiding any possible magnetic interference with other equipment.
High temperature neodymium magnets.
