Coincident Triumph vs. Zu Druid

We've had the ZU Druids for about 3 years. They handle anything we throw at them (and that is quite a wide range of music). With our smallest amplifier we can play the Druid to any level we want.

Our amps also work well with the Coincidents, but our S-30 (our smallest amplifier) is not enough power IMO for the Coincidents, although it sounds fine on them. I think the volume level is a matter of taste in this regard and a lot depends on the listening room. I'm often accused of playing things too loud :)

So the difference is efficiency and the Druid has slightly more bass (but overall that is probably not going to mean a whole lot). Otherwise with our amps the two speakers sound very similar.

the coincidents

I have heard both, only on demos and at different times, however fact as above pointed out above, power could be more an issue than sound, but I would also note that the Zu is really going to excel close to walls and out in the middle of a room.. I believe those coincidents will require a bit more space from what I could tell on the demos at a dealer, Just some thoughts to think about with your room. And the Zu's are in fact 6 db more efficient and are also 12 ohm load vs. 8 ohm which is nothing to sneeze at with small amps, resale is probably pretty good on both, but the Zu's seem to disappear within days and get a pretty good bulk of cash back out of them.
