Quad ESL 2812 and earlier Quad tweaks

Planar Speaker Asylum

Welcome! Need support, you got it. Or share your ideas and experiences.

In the April, 2106 issue of The Absolute Sound, Robert E. Greene reviews the new Quad ESL 2812, the latest iteration of the ELS-63 series. On page 94, Greene discusses using a DSP device to fill in a "hole" in the 150-500Hz range. Two devices he mentions are the Lyndorf Audio RoomPerfect and Uli Bruggemann's Acourate correction system on 989s.

I guess as an older audiophile who is unfamiliar with these devices, what they do and how they work, I wondered in anyone on this list has gone this route and may care either to point me to some articles or reviews with which I could further research this tactic or report on their experiences with it/them?.

Many thanks,

George
