GENERAL DESCRIPTION
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.
