The majority of the in-ceiling loudspeakers installed were CMS 501PI, which benefit from being supplied with a separate pre-install back can. These zinc plated, fully wired back cans are designed to be pre-installed into newly constructed, non-suspended ceilings leaving the product to be inserted at the final system commissioning stage of the install. This makes them particularly suited to large scale, potentially complicated new-build developments such as the Burj Khalifa, where the contractor needs to get in and complete installation and commissioning in very strict time frames, says the company.
Also among the substantial CMS specification were over 50 CMS 801DC, Tannoy's larger format high power in-ceiling system built around a 200mm (8") Dual Concentric driver. Designed specifically to deliver full bandwidth audio coverage at higher SPLs, the CMS 801DCs were a perfect solution for more demanding applications such as in the ballroom.
Acoustic and ELV consultants PMK International, who have a regional office in Dubai, were commissioned by Emaar Properties, the developer of the Burj Khalifa, to design and specify the installed sound requirements for the project. The AV installation itself was carried out by technology integrator Bond Communications.
