Good to hear the RF7 make you happy. I’m considering the RF7 iii myself. If you go down the MINI DSP route, I strongly advice to get the HD variant. This gives you the opportunity to create a steeper curve at your low frequency cutoff point. I use two R115SW in my room and have a low frequency and 20hz as cut off point because they are designed to output as low as 18 hz. Trying to let them output below 18hz only generates port noise.
