Description
The Adastra CH15 is a low impedance round PA horn built for general purpose and contract industrial installations. It runs at 8 ohms and handles 15W RMS, making it a practical choice where you need clear voice or music coverage across a work area, yard or public space. The design is straightforward and hard-wearing, so it suits jobs where the speaker has to earn its keep day after day.
We make the horn from aluminium, which keeps the weight down while standing up to knocks and general wear. It comes fitted with sturdy steel adjustable mounting brackets, so you can angle the horn to point coverage exactly where it is needed. There is 120mm of good quality two core speaker cable already attached, giving you a solid connection point to wire back into your system without any guesswork.
With an IP33 rating, the CH15 copes with light exposure to the elements and dust, which makes it a sensible option for covered outdoor spots and busy indoor sites. As a low impedance horn, it wires directly to an amplifier without needing a 100V line transformer, though you should watch your total load across the amp. It is a simple, reliable unit for anyone putting together a paging or background audio setup on a budget.
