In the past it was difficult to understand the passenger information announcements at Keleti station because of the strong reverberations.

The concert hall of the Kodály Center boasts the first IVS line speaker in Europe, which is 8 meters long. We use it every day to broadcast call signals before concerts, to conference concerts and to make protocol speeches.

IVS line speakers have been installed in the Arena Press Conference Center. The two column loudspeakers provide perfect coverage for the entire area of ​​the room, with appropriate dynamics and a relatively wide frequency range.
