there is no comparison except that the Tone is more efficient ,even the Dulcet destroys the Tone ,I owned the druids and tone, they are both gone ,they use a cheap Chinese electravoice driver the dynamics are very good that is where it ends compared to a solid single driver the precesion and inner detail is decent at best , Any one of the Reference loudspeakers will beat it hands down I had over 3 months each and even run the drivers in for over 300+ hours hoping to fix the fuzzyness in the inner midband no luck.I worked voicing Electrostatic panels for Final sound so I would say I qualify to know what is good,also I have had every type of loudspeaker ever made ,
meaning stats , dipole, ported, transmission line .sealed single and multiple driver. As long as you have quality electronics , cables the Reference loudspeakers will never let you down ,you may hate that they are so reveiling with bad recordings except this or by a speaker
like a living voice that is warm and forgiving -aka Sonus faber ,-safe speakers they are called ,Masking speakers is a better term!
