This big ProAc really moves the game on quite a bit. So what’s happening here then, what makes this speaker extra special ?
Well, we have a ribbon tweeter that just seems to shimmer. ProAc are one of the few speaker manufacturers that are able to exploit the wonders of ribbon technology.
Music on a large scale is what the D40’s are all about. However, they don’t require silly amplification, only good amplification.
Ribbons love valves so we’re talking Leben and Nagra here but don’t forget the Lavardins, probably the only solid state amplifiers with the musical purity needed for this revealing speaker.
