The problem with this thread is you’ll get a lot of opinions based on older Fortes. I’m sure few here have heard the IIIs, which have revised drivers and crossovers. I have Heresy IIIs. Many describe the Heresys as "bright," "fatiguing," or "brittle," but I don’t find that to be the case at all with the H-IIIs, and I’m used to the warmth of Spendor classics.
I owned a pair of Vandy 1Cis for about a month and they were the brighter speakers when their treble trim was set to neutral. This was in the same room, with the same gear. The Vandys did have a wider sweet spot and dug deeper, but as with all mid-efficiency speakers, they required some volume before they’d open up. For low volume listening, it’s no contest, the Klipsch speakers will produce greater bass at low levels.
