About Redback® Speaker Drivers
Each custom designed speaker and transformer combination has been specifically engineered to ensure a wide frequency range and dispersion angle, plus a high sound pressure level (SPL) ensuring excellent music and speech intelligibility; which is highly desirable.

Each transformer is fitted with multiple power tappings which are selected via a tab on the top of the transformer.
