Last year, London’s Factory Studios became the first UK facility to include a Dolby Atmos-licenced suite for commercials and trailers, and has now spoken out about the 35 Alcons CRMS Cinema Reference Monitor System speakers installed as part of the project.
Founded in 1997, the award-winning facility has produced the sound for projects by many high profile clients including EE, O2, Renault, Nike, Three, eBay, Sainsbury’s, Tesco, Harvey Nichols, BT, Sony and Samsung.
“We aim to be at the forefront of developments in audio technology,” said Factory sound engineer Ben Firth. “We have a close relationship with Dolby and are always interested in new formats. We were introduced to Atmos at an early stage and, with an increasing volume of work, have been able to build two new sound studios, one with dedicated 9.1 surround and Atmos monitoring.”
Laurence Claydon, founder of technology consultancy Cinefilm, was brought in to work with White Mark acoustic consultants on the project.
“The critical thing for an Atmos array is to get the loudspeaker positioning very accurate and to ensure each one has enough power and dynamic range for each position,” he explained. “Traditional cinema drivers are generally built down to a price. With horn-loaded compression drivers, distortion rises with frequency above the break-up point at 3kHz. Alcons pro-ribbon loudspeakers do not suffer with break-up or increased distortion at higher frequencies, so are clean beyond the upper limit of human hearing at 20kHz.”
“When building an Atmos room with so many speakers, you only have one chance to get it right,” Firth added. “I listened to a few configuration options and the one that immediately stood out was CRMS for the screen. I’ve never been a fan of horn-driven speakers and so Alcons immediately ticked that box. Low distortion and flat response at all SPLs make the system really nice to listen to for prolonged periods. The richness and clarity of the CRMS are outstanding.”
For the surround system 20 CCS-3s, four VR8s and four CRS8s were chosen. The low end is handled by four ultra-slim CB181 subs, with ten Sentinel 3 amplifiers driving the system.
Another advantage of Alcons pro-ribbon technology is that it makes the loudspeakers considerably lighter than traditional designs. “It was a challenge to design and install a full Atmos-licensed monitoring system into quite a small room at the top of a five storey building,” remarked Claydon. “Every millimetre counted and the light weight of the Alcons speakers helped with both the transport and precise positioning.”
According to Firth, “The build quality is fantastic, with no negative effects on driver performance. As well as delivering a flat frequency response with crystal clear highs at all SPL levels, the bass response is very impressive. It is imperative that all our mixes sound the best they can, not just in the mix room but in the cinema, TV, radio and online. Extensive feedback from our clients shows that they do.”
“It’s all about making sense of the detail and not losing it, which is what the pro-ribbon driver technology does so well. I believe there’s very little out there that can challenge Alcons,” added Claydon. “Alcons CRMS speakers are ideal for critical mix work, but they have the same dispersion pattern as a cinema system. Mixes on them translate well to different playback systems, but they have an extra layer of quality and clarity.”
