- removed the limiter flags again and addressed the underlying problem properly.

Browse source 
The real issue is that the number of unattenuated sounds was unchecked and the near limit never kicked in.
To do this properly it is necessary to adjust the limit distance by the attenuation - zero attenuation must mean infinite distance and for high attenuations the distance must be lowered for limiting to work as intended.
The limit for the Doom boss sounds was increased to 4 to compensate for this change.
