Frequently asked questions
How much does an EM Acoustics system cost?
System pricing depends on the room, the coverage required and the amplifier and processing that goes with it, so we quote against a system design. Send us drawings or a description of the space and we will come back with a proposal.
Which EM Acoustics series should I specify?
HALO is the line array family, from the large format HALO-A to the compact HALO-C. Reference Series is the newer point source family, designed so one series covers everything from small fill to main system in a single venue. EMS is the established range for install and production. Tell us the application and we will recommend the right series.
What is a cardioid subwoofer and do I need one?
A cardioid subwoofer directs low-frequency energy forward and cancels it behind the cabinet. The CS15 and CS18 are worth specifying where you need to keep sub energy off the stage, out of an adjacent room, or away from a neighbouring property. In the Gulf, noise limits at outdoor venues make this a common requirement.
Are EM Acoustics loudspeakers passive? What amplifiers do I need?
The range is predominantly passive, driven by matched DSP amplifiers. That is a deliberate design choice, not a cost saving. We specify the amplifier and processing as part of the system design so the two are properly matched.
Can I hear a system before specifying it?
Yes. Contact us to arrange a demonstration in Dubai, or for larger projects we can discuss a listening session on site.
Do you provide system design and commissioning?
Yes. Our technical team handles prediction, system design, installation support and commissioning across the region, so the system performs as drawn.
What warranty comes with EM Acoustics?
Full manufacturer warranty, administered regionally by 7HERTZ as official distributor, with no need to send anything back to the UK.
