NEXO GEO M10 beats the competition at an award-winning cultural centre in Finland

Mar 2026 | News | Theatres | GEO M10 | Finland

Almost 300km north of the capital city Helsinki lies the Finnish town and municipality of Pieksämäki where a population of just over 17,000 people enjoy a world-class performing arts and exhibition venue in the form of the Cultural Centre Poleeni.

Located in the centre of town, this award-winning building includes a 342-seat hall, a municipal library, an exhibition space, a meeting room, a foyer, a fireplace corner, a café and a ticket service office.

Originally opened in the late 1980s, the venue operators recently issued a public tender for a new sound system, in which many well-known PA manufacturers participated. One of the key selection criteria was a test performance arranged in the venue, following which a NEXO GEO M Series line array demonstrated by Espoo-based AV technology specialists Electro Waves was selected as the new system.

“Poleeni was already equipped with six NEXO P12 loudspeakers and an NXAMP4X2MK2 amplifier, which we earlier supplied as a part of the total NEXO system delivery» reports Marko Koskimies, Pro Audio Sales at Electro Waves.

The new system comprises of twelve GEO M10 speakers and three L20 subwoofers in a cardioid setup. Four NEXO ID24 speakers were added to the front edge of the stage to complete the audio picture of the front rows of seats. These installation model speakers, like the other speakers in the system, are equipped with fabric-covered front grilles.

“The ID24 speakers ended up in the original order to ensure that the sound coverage would be as even as possible, and the sound direction would be correct even in the middle front row seats. The amplifiers are NXAMP4X4MK2 and NXAMP4X2MK2, and the system is controlled by the NEXO’s NeMo software. In addition, two NEXO P10 loudspeakers were installed for rear/surround use.”

The installation was completed together with Poleeni’s technical staff, after which venue staff were trained in the use of the system by Minka Matikainen, Technical Specialist at Electro Waves.
