It has been part of Meridian HT processors since at least 2004. It operates sligthly diffrent , its active under 300Hz and also corrects the time domain you build several Filters with sligthly diffrent target reverb times . The nodes does not only have higher amplitude but also ladt longer in the time domain.
The 300Hz cut has to do with some phycoacoustic concern with direct vs reflected sounds , the brain actually have a kind of "gating function" even in a ver reverberating room you can usually spot sound sources. So messing things much with the direct sound to achieve better reflected response mau not be perfect. I have not fiddled with mini dsp , but certainly modern products will have settings for you to fiddle with. But as usuall DSP can make a good thing better . Not save a bad system. For example realy awkward speaker placement or speakers with weird polar paterns migrh be problematic. Or trying to fill the nulls . Damping the peaks may be well and good but trying to fill the nulls with 10-20db more acoustic output places high demands on powerhandling and linearity. Robust speakers are recommended. Enjoy. I really like room corection , a bonus is that subwoofers blends in much better, the disconnect that always there is much less obvious. -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
