“Hall of Heroes” is the part of the The Hall of Heroes chapter in Bioshock Infinite and it has 2x Voxophones. Bellow you will find screenshot guides and explanations on how to find all of them.
As soon as you enter the “Hall of Heroes” just follow the path and you will get to a fork in the road. To the right is a Vending machine and to the left is the Tickets room. Inside the Tickets room is where you can find the Voxophone.
During this chapter you will get to a part where you enter “The First Lady” wing. Just keep doing the mission and you will come across a room that holds the “Lady Comstock” statue praying. Go right from there and you will enter a room with a false fireplace and a chair that holds the Voxophone.
