The APH range of lightweight plastic weatherproof re-entrant horns have been designed for high quality sound reinforcement. Manufactured in a strengthened ABS molded compound with UVL (ultra violet light) protection and supplied with a high grade stainless steelepoxy coated U- bracket.

Offering clarity of speech and high efficiency, these horns are suitable for communications or signal warnings. Being non-corrosive and resistant to salt laden air, they are suitable for use indoor and outdoor. In addition they are also ideal for marine and industrial applications as they are unaffected by most chemicals.
The 20 Watt and 30 Watt versions of APH range of plastic horns are available as standard, with 1 x PG9 and 1 x PG9 Blanking Plug cable gland entries allowing the installer to loop in loop out the cabling thus avoiding the need for an additional junction box. 

ENC models are compliant to the EN54-24 standard for Voice Alarm systems, it includes a capacitor for DC line monitoring.
