Sennheiser Envelops Rodin Museum in K-Array Audio

Philadelphia, PA, USA (November 26, 2012) -- The Rodin Museum is one of Philadelphia's prized museums, and has been run by the Philadelphia Museum of Art since 1929. The museum, which contains a priceless collection of 'the father of modern sculpture' Aguste Rodin including "The Thinker," attracts tens of thousands of visitors per year and is not only a landmark in Philadelphia, but also a major international tourist attraction. Recently, the museum enhanced its visitor experience by installing a K-array audio system, distributed by Sennheiser.

Following a major restoration project to its garden and museum facility, The Rodin Museum reopened last September with the new K-array system, which was designed to facilitate background music as well as museum announcements and other public address functions.

Considering the visual and artistic context of the museum, the project team required an aesthetically subtle audio solution that would not divert or otherwise distract attention from the art itself. From a technical point of view, the audio system had to deliver high quality audio to accommodate the program requirements, while minimizing the amount of reverberation that is common in acoustic environments containing smooth walls and marble finishing.
Four K-array KV50s were installed on the walls of the main gallery.
The system was conceived by 3rd Street Services, in conjunction with Jim Fraatz and Steve Keever of the Philadelphia Museum of Art and installed over a three-month period. K-array distributor Sennheiser, along with local AV consultant 3rd Street Services, arranged for a demo of a K-array system — which was ultimately chosen for its outstanding sound quality and dispersion qualities, in addition to its minimalist, small-footprint design.

Four K-array KV50 line array speaker elements, each containing eight 1’’ neodymium transducers, were installed on the walls of the main gallery at about six feet high, accompanied by two K-array KU36 subwoofers on the ground - which were chosen for their compactness and portability.

A similar solution was implemented in the Library, which contains a nearly 30' high vaulted ceiling. Eight K-array KT20CW point source compact speakers were recessed in the vault itself, accompanied by two KU36 subwoofers on the ground — which could be easily removed if required. The entire system was powered by four K-array KA7-7 amplifiers.
The Library features two K-array KU36 subwoofers, among other speakers.
According to Ted Sheppard of 3rd Street Services, the KV50s were selected due to their transparent sound and extreme compactness; characteristics also shared with the KT20CWs. Despite their small footprint, the KT20CWs are capable of distributing audio content at 107 dBs at a frequency range of between 150 Hz and 18 KHz.

From the beginning, the installation performed as expected and only required an additional DSP preset, which was promptly loaded on the KA7-7 amplifiers. The new preset helped align the audio dispersion of the two KU36s, making the system more congruent and even more efficient.
