Hi,
2016 Stereo Room is not currently free, nor available for sale individually. It has been given away through various promotions in the past, but it has been several years since the last promotion.
You could download the demo of our SP2016 Reverb, which is a revamped version with a fuller feature set and improved dsp: https://www.eventideaudio.com/products/plugins-reverb/reverb/sp2016-reverb
