Lima restaurant overcomes poor acoustics with Genelec

Peru’s Osaka restaurant has been fitted with a Genelec 4000 Series loudspeaker stereo system by integrators Sonar Audio to achieve neutral sound throughout the acoustically untreated space.

Osaka, located in Peru’s capital Lima, serves Japanese and Japanese-Peruvian (Nikkei) cuisine from the basement of a new co-operative building in the San Isidro district.

Consistent audio performance in the 500sqm area posed a challenge due to its poor acoustics, and in addition, the client was also keen to maintain a clean restaurant aesthetic. A further requirement was for part of the restaurant space to be able to be turned into a lively entertainment space after dinnertime, with the option to host DJ parties and celebrations long into the night.

Sonar opted for a stereo system installation using an array of Genelec loudspeakers from the 4000 Series. The installation was required to have the option for a stage area with ambient music, but also be able to deliver excellent quality and power in the dining, bar, lounge, toilets, terrace and private areas. Sonar worked one year in advance from the plans with architects Costa+Herrera, who were involved in the entire process. The architects’ work made it possible to deliver the solution which provides a clean aesthetic and quality sound throughout the space, with precisely located speakers.

“When we were commissioned to design an extremely sonorous sound system for this client I couldn´t think of any other gear than Genelec, mainly because of the reliability,” said Clifford Day, director of Sonar. “The first requirement was to fill this big restaurant with good sound and also take into account that the sound in the lounge and bar should be powerful enough to impress clients when needed. What I liked most about this project was that the intention was not to create a club-restaurant; this place must be always a restaurant first and foremost, but the sound system should be as good as it can be without the requirement for really high pressure levels. Again, this is a perfect situation to work with Genelec, whenever you need the best sound without the requirement for very high SPLs (More than 114dB SPL in all areas). With a good selection of Genelec pieces we were able to fulfil this expectation.

“The second problem was the need to control sound in a large area with a lot of concrete and glass. We added some diffusers and placed the speakers in their best position to achieve a tight sound. Reverberations cannot be felt and the sound is very lively. Budget is always an issue in projects such as these, and working with Genelec, you know you get a product that is complete and ready to tweak and get the most out of it. If properly done, sound behaves the way needed and results are better than expected by the clients. Exceeding the goal is always gratifying.”
