Kara II fulfils demands of Swedish venue\u2019s progressive program<\/em><\/em><\/em><\/p>\n\n\n\n

\n\n\n\n

J\u00f6nk\u00f6ping, Sweden<\/strong> \u2013 March 2021.<\/strong> The impressive, airy Kulturhuset Spira<\/a> (Culture House Spira) is a seven-story glass-and-wood structure on the banks of Lake Munksj\u00f6n<\/a>. Leading Swedish architect firm, Wing\u00e5rdh<\/a>, designed the structure that houses four stages and hosts a progressive program of music, theatre, dance, and children\u2019s programming and serving as the headquarters for the regional Sm\u00e5lands Music & Theatre<\/a> team. Spira translates as \u2018grow\u2019 or \u2018aspire,\u2019 and this spirit infuses the team at Spira\u2019s desire to remain at the cutting edge of technology. When they recently embarked on an upgrade to the venue audio system, they opted for L-Acoustics Kara II<\/a>.<\/p>\n\n\n\n

L-Acoustics was the first and final choice of sound system for Spira. When the center opened its doors to audiences in 2011, it was with a Kara system and it has served well in the intervening years. However, demand for a larger and more powerful system increased over the years and, with L-Acoustics releasing its Kara II, local integrator JLE Audio AB<\/a> was able to offer a cost-effective solution to upgrade to the venue\u2019s existing Kara to Kara II and supplementing it with additional new Kara II enclosures.<\/p>\n\n\n\n

\u201cThe J\u00f6nk\u00f6ping\u2019s Sinfonietta<\/a> performs several concerts a year here,\u2019 says Spira Head of Sound, Jack Strandberg.\u00a0\u201cThe classical musicians, guest conductors, and sound technicians that work here all demand good sound. That\u2019s why we chose the L-Acoustics brand with its \u2018hi-fi\u2019 sound, clarity, and homogenous\u00a0response to give the absolute best audio experience for our orchestra guest shows, conferences, and for the audience.<\/p>\n\n\n\n

\u201cWhen we decided to upgrade, Kara II was a great option, particularly as the new Panflex \u2018fins\u2019 can eliminate early reflections. When we found out that we could upgrade our existing Kara, it made the choice even easier.\u201d <\/p>\n\n\n\n

Work began in late autumn last year and was completed in January. With support from the application engineers at L-Acoustics, and working closely with the team at Spira, JLE designed the new Kara II system, with the goal of ensuring even, quality coverage for every seat in the auditorium.<\/p>\n\n\n\n

\u201cL-Acoustics products and their system design are outstanding, offering high-end technology and sound quality of the highest level,\u201d says JLE\u2019s Johannes Jonsson. \u201cWe knew the system would satisfy both in-house sound engineers and guest productions. L-Acoustics Soundvision was used to create the whole setup. It\u2019s very helpful to have such great software to get a clear picture of the results we can expect.\u201d<\/p>\n\n\n\n

Strandberg notes that having a long-standing relationship with JLE and L-Acoustics meant the collaborative process throughout the project worked extremely well. \u201cI emailed L-Acoustics CAD files of our concert hall and got back a detailed Soundvision\u00a0file for the venue,\u201d he says. \u201cThe direction from me was to have the KS28 floor subwoofers in cardioid, together with our original SB18 center subwoofers, also in cardioid mode, and to have an even spread from the Kara II and subwoofers throughout the entire auditorium.\u201d\u00a0<\/p>\n\n\n\n

The final setup comprises main hangs of 14 Kara II per side with four flown SB18 in the center, plus a further four ground-stacked KS28, two each stage left and right. Eight 5XT<\/a> are positioned evenly across the stage lip to provide frontfill, whilst four X8<\/a> are used for balcony fills. The system is driven by nine LA4X<\/a> and one LA12X<\/a>\u00a0amplified controller with a P1 processor<\/a> managing audio distribution over AVB to all amplifiers.<\/p>\n\n\n\n

All amplified controllers were positioned on a grid on the top floor of the building. The team wanted cable runs to the Kara II to be as short as possible, so the installation process started with cabling. The second task was to find the best points for the four Chainmaster hoists that would lift the left and right Kara II\u00a0hangs into position. \u201cFrom there, the rest of the installation was pretty straightforward,\u201d reveals Strandberg. \u201cThe final job was to spend two days listening and measuring the first and second balconies, and the ground floor with front fills and outfills.\u201d<\/p>\n\n\n\n

\u201cThe result we got was very close to what we had seen in the software,\u201d adds Jonsson. \u201cThe Autosolver tools in Soundvision did an outstanding job of achieving inter-element angle optimization by providing a refined analysis to improve sonic performance. The AutoFIR filter tool then assists with system tuning of the mid and high frequencies, further improving uniformity and flatness of the high-frequency response by determining and applying linear-phased FIR filter to zoned groups within the array.\u201d<\/p>\n\n\n\n

JLE has also recently upgraded the PA for Spira\u2019s caf\u00e9 stage with two hangs of two A10 Focus<\/a> and one A10 Wide<\/a> positioned stage left and right, plus a center hang of three KS21<\/a>, all powered by two LA4X amplified controllers.<\/p>\n\n\n\n

\u201cMy main goal was to have even sound across the whole venue,\u201d concludes Strandberg. \u201cHaving L-Acoustics in both spaces ensures that wherever our audience is, they are assured a great sound experience, and we are very happy with the final result. The system also allows us to continue growing our progressive program and to maintain our legacy of offering cutting edge technology.\u201d\u00a0<\/p>\n\n\n\n
