The Dayton Audio D1057T is a horn speaker driver featuring robust materials and design. It is a model recognised by installers and audio professionals. It uses a phenol-impregnated cloth diaphragm to provide a clean, articulate sound. A cast aluminium front panel, plastic rear housing with gasket and stainless steel parts ensure long-term reliability for both indoor and outdoor use.
The D1057T has a response that lends itself perfectly to sound reinforcement or PA systems, thanks to its effectiveness in the frequency range of human voices and the midrange detail of stringed instruments. Its impedance curve is also easily manageable for simple, versatile system design.
This model is also completely ready to use. With its built-in 70V transformer, the selectable sockets allow you to customise the output of each speaker to suit a multitude of locations and circumstances. Use the high-level sockets for high vaulted ceilings or wherever you need a high sound pressure level. Lower level sockets are available for installations requiring lower sound pressure levels.
