After a turbulent renovation phase, the renowned Stuttgarter Schauspielhaus
opened again after several phases of rebuilding. Also on board: A new sound
system by Alcons Audio. After the last renovation phase, the main room of the
Theatre of the Year award-winning Stuttgarter theater, now has a maximum of 670
seats, which all offer a very good listening experience thanks to the new sound

Frank Burger, head of the audio and video department of the Schauspielhaus,
explains the decision for an Alcons system: “From a natural, balanced sound for
unobtrusive theater reinforcement to a powerful sound for modern productions and
concerts a versatile system was required.”

Thomann Audio Professional, as technical service provider involved in the project,
installed the system during the first restructuring phase of the Schauspielhaus.
Carsten Land, project engineer Professional Audio at Thomann, explains the
requirements of the theater that were to be met by the new sound system:
“Compactness was clearly one of the main requirements – and the LR7 is one of the
most compact line arrays on the market.”

Frank Burger adds: “The compact size of the system, of course, is really an
advantage for us; As permanent installation, it integrates excellently in the spatial
conditions of the Schauspielhaus. The steeply rising auditorium is optimally covered
by the Alcons line array, whereby the aural impression of the sound is
homogeneous in almost every seat. The natural clarity and open, yet punchy sound
offers a lot of pleasure when using the system.”

The main system of the Schauspielhaus consists of left / right each 8x LR7 micro
line array (4 “pro-ribbon, 1x 6.5” woofer) and 2x LR7B, micro line array bass. 4x
LR7-120 micro line array operate as center cluster. As down fills 2x VR12 monitor
(6 “Pro-Ribbon, 1x 12″ woofer) and as LFE 2x BF362i (2×18”) subwoofer are used.
The system is driven by ALC2 and ALC4 (2x 1KW, 2x 2KW) Amplified Loudspeaker
Controllers with DDP (Digital Drive Processor).

The Alcons LR7 a is a passive two-way loudspeaker system, based on Alcons’
multiple-patented pro-ribbon transducer technology. Ultra-compact and ultra-light,
it is nevertheless a true line array system that can be used as a vertical as well as
horizontal array. Besides in fixed installations, also mobile use is possible. Like all
Alcons systems, the LR7 offers an uncompressed, high-performance and uncolored
sound, with exceptional speech intelligibility, precise pattern control and a high
direct sound at large distances.

The Stuttgart State Theater are the largest three-section theater (“Drei-Sparten-
Theater”) in Europe, consisting of the Stuttgart Opera, the Stuttgart Ballet and
Stuttgart Theater. The since 2001 “Schauspielhaus’ called former Kleine Haus
(“Little House’) was rebuilt from 1959 to 1962 after its destruction in World War II
and renovated in recent years in two phases. The Schauspiel Stuttgart is considered
one of the most innovative theaters in the German-speaking countries.
