Quoted from TheAudioBeat Roy Gregory article on the new Trio's
"There was also a set of Trio XDs with BassHorns, which is where the listening started, but it was instantly apparent that, even in passive form, the G3/SpaceHorn combination was in a completely different league, leaving the older speakers sounding thin, disjointed and musically awkward. In fact, a direct blind comparison might lead you to question whether the G3 is a horn speaker at all, such is its sense of rounded warmth, body and integration. Voices and instruments were significantly more natural and more naturally dimensioned. The sense of pace and timing in music was far more explicit."
