Vector Monitors - VRM-115A

The Vector series monitors are designed with the same no compromise approach as all HH PA. These are not FOH cabs in a different box.

They are not ‘multi-purpose’ cabs. These are pure-bred stage monitors. They share little with the FOH cabs other than the ‘full system design’ philosophy, and the same attention to detail and purpose.

They are optimised for mid range clarity and intelligibility, punchy bass and a focused sound field, from a compact low profile format to leave the stage for you. From asymmetric horn flares that focus treble where it is needed, to the exact number of turns of coil wire every aspect of design is considered to ensure as much mid definition as possible without harshness.

All models are available as passive or active systems, with the active systems including powerful EQ and the ability to power an extension cabinet.


A 250W power amp and versatile preamp are added to the passive system to give local control of EQ and level for a flexible monitoring solution.

Add a passive VRM-115 coupled to the speaker out for serious sound pressure and coverage.
