Determining frequency response of a room

  Hello all,
  
  I am trying to get a frequency response of an arbitrary room using ANSYS 2019 R1. Unfortunately I have not found any guides pertaining to the new acoustics module and all are based on the older ACT acoustics.
  
  Currently I have set up a room with a speaker in the middle at around human height, and I am using an incident wave source with a back enclosed speaker. Trying to simulate a human singer. Most tutorials use mass source however I am using this source since I am able to position it at different places, it looks like it is no longer possible to place a mass source on a node.
  
  I have two questions, first, what is the idea behind the radius of pulsating sphere ? does it indicate the size of the speaker driver ?
  
  Also in the simulation, the frequency response becomes flat after 2500 Hz , while I am trying to attempt a full response curve from 0 - 24k Hz. Is this due to the coarse mesh or is there an issue with the boundary conditions I have set up ?
  
  I have attached the project file here.
  
  Thanks in advance for your help.
