Lambda Labs was recently charged with that task of equipping 'The Rooftop' - an exclusive venue at the St. Regis Hotel, Doha.
To fulfil the requirements made by the bar, located on the roof of the five-star Qatari hotel, 36 black and white Lambda Labs speakers were installed.
Miguel Escada, founder of the Portuguese Pro-Audio company 'Auditiv' that was in charge of the sound installation, explains: 'The task was clear right from the start. [The bar] was to be seamlessly integrated into the uncompromising concept of the illustrious St. Regis chain of hotels. This is why for 'The Rooftop' in Doha a renowned Lebanese designer was engaged who would do justice to the visual demands, the F&B manager Marco Syrbe comes from Germany, and I was supposed to guarantee that guests - as well as artists - up here would be provided with a unique experience. The operators wanted a perfect sound solution."
He continues: "The installation had to maintain a highly even sound distribution across the entire hearing and dancing area, especially in the low frequency range, and it had to possess a precisely reflected stereo signal with an excellent - and also very even - impulse response. And it had to be weather-proof. Besides, once the later hour turns the bar into a nightclub, it calls for very high SPLs and all of this had to be realised in an optically appealing fashion, like the one I was able to find with Lambda Labs: discreetly beautiful state-of-the-art loudspeakers as a matter of course. Most of them are custom made with a shiny white Polyurethan coating and actual white woven front fabric."
14 white MF-15A create a 40-metre horizontal line source and provide the entire rooftop with consistently dry bass. At 100 Hz, eight opposing black and white TX-2A take over to radiate a well tempered and enjoyable performance across the terrace.
With the bar's superstructure being higher than the opposing glass front, the TX-2A on the bar side were installed overhead, raising the high tone units to the same level as the TX-2A mounted on distance rods on the glass front, guaranteeing a more homogeneous sound reproduction. The Lambda Labs EPS Rigging System makes this possible.
The 6 VIP lounges situated on the left and right hand side of 'The Rooftop' are also located within the range of the MF-15A line source and - coupled with two wide dispersion CX-1A loudspeakers on the frontside - are incorporated into the musical events. The DJs can hear themselves on the high resolution CX-3A stereo monitoring right next to the DJ pulpit, and feed their music into the digital control unit.
