The Brierley Hill-based audio company concluded that Toshiba’s bi-flow RAS console split system was one of the quietest available, with a sound pressure range of just 31-46dB(A), equivalent to a quiet bedroom in the dead of night and the hushed environment of a university study library. 

Nigel Kuscher, managing director of Ref-Sol, which installed the Toshiba system, said: “Our client specialises in very high-end Hi-Fi systems, which require the lowest possible ambient noise to preserve outstanding audio reproduction. They established that the Toshiba bi-flow system was one of the quietest available, and would deliver the comfortable environment needed for customers to audition equipment without detracting from the audio experience.”

He added: “The other consideration was aesthetic design, in order to blend in with the upmarket ambience of its retail outlet and listening studio. The discrete appearance and flowing curves of the Toshiba bi-flow console unit were a perfect match.” 

The design of the Toshiba bi-flow system allows air discharge from the top and bottom of the unit, reducing turbulence and associated sound emissions while delivering excellent comfort conditions and energy efficiency.

It uses the latest digital hybrid inverter technology to precisely match output to demand, further reducing sound levels, and is equipped with a fine-filter system to ensure optimal indoor air quality.

The Sonority Design system delivers a total of 7.2kW of cooling and has an energy label rating of A++. Indoor units are Toshiba’s console model RAS-B18UFV-E1, and the outdoor unit is model RA3M27S3AV-E.
