The new hall can accommodate 15,000 people, though there is only seating for 2,500.
The new concert hall is the biggest in the Belgian and Flemish capital and will challenge the supremacy of the Antwerp Sportpaleis.

Only a couple of acoustic tests in June are needed before the new concert hall can be opened. A score of concerts are already planned including Jamiroquai (10/07), Mylène Farmer (13-15-16/11), Indochine (12/03/2014), Christophe Maé (14-15/03/2014) and Robin des Bois (9-10/05/2014).
Brussels Expo that operates the exhibition centre says that concerts, ‘spectacles’, fairs, sports events and conferences can all be staged in the renovated Palace 12.
The music industry has wanted a big, new concert hall in Brussels for some time, especially as rival venue Vorst Nationaal cannot accommodate big shows like those of Mylène Farmer.
The new concert hall can easily be reached using public transport. Cars and coaches can travel via the Brussels orbital. At the site there is room to park 12,000 vehicles.
The new hall is the first to be finished as part of the Neo project that envisages a complete renovation of this site at the edge of the city. Renovation work on Palace 12 cost 20 million euros.
