Why engineers choose EM Acoustics

EM Acoustics was founded in 2002 by Ed Kinsella and Mike Wheeler and has grown from a converted fire station into a factory at Dunsfold Park in Surrey. Woodworking, cabinet assembly, paint spraying, final assembly and quality control all happen in that one building, which is unusual in an industry where most cabinets are outsourced.

The company built its reputation on passive loudspeakers at a time when the market was moving toward heavy DSP correction. The argument is simple: get the enclosure and the components right and the system needs less processing to sound neutral. That thinking runs through the whole range, and it is why EM Acoustics turns up so often in rooms where the audience is listening closely.

The range at 7HERTZ

  • HALO line arrays: HALO-A large format and HALO-B medium format two-way elements for touring and large installs, and the compact passive HALO-C for theatres, corporate AV and fills.
  • Reference Series: R4, R5, R6, R8, R10 and R12 point source cabinets. A complete single-manufacturer family, from the smallest fill to main system duty, so one series can cover an entire venue.
  • EMS Series: EMS-41 through EMS-156, including the EMS-81X and EMS-101X. The established install and production range.
  • S Series subwoofers: S8, S-12, S-15 and S-18 for conventional applications.
  • CS Series cardioid subwoofers: CS15 and CS18, where pattern control is needed to keep low-frequency energy off the stage or out of a neighbouring space.
  • M-C12 and M-C15: coaxial stage monitors that run from a single amplifier channel, on the floor or on a pole.

Where it fits

Theatre, houses of worship, corporate venues and live production, particularly where the system has to sound natural and disappear visually. UK credits include the Royal Shakespeare Company, Chichester Festival Theatre and the Natural History Museum.

Buying EM Acoustics in the UAE and GCC

Passive systems put the amplifier and processing decisions at design stage rather than leaving them to the cabinet, so the specification matters more than usual. As official distributor we provide system design, prediction and commissioning from Dubai, with manufacturer warranty handled regionally. Talk to us before the drawings are fixed.

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.
