Chris from earlier in this thread:
Expect the Duntechs to be very truthful to the recording. Not overly bright or bass-heavy. Not overly warm or intentionally "musical". Accurate. That is why a lot of recording/mastering studios used them (and still do).
They have a narrow field of dispersion (to limit directly reflected sound), so you need to set them apart 45-70 degrees, toe them in so they point directly to the listening position with tweeters at ear height, and there will be a small sweet spot in the middle with the best and most accurate sound. The narrow dispersion also limits the soundstage to between the two speakers... although some of them are really big speakers and can work well in big rooms.
The top of the Duntech range are the Princess/Crown Prince and the huge Sovereign. You need a big room for these, or lots of bass-trap acoustical treatments, as they have heaps of bass energy and will activate the room modes which may give the impression of muddy/sloppy bass - but when you correct these room issues or reposition you will find that the bass is very tight indeed... and very resolving, so a bass drum sounds just like a bass drum, not just a "doof" sound. The big sealed enclosures no doubt help this.
They do need a high-current amp, especially the top of the range Duntech models, and after testing a few I can recommend the ME amps, but there are quite a few others out there that that will work fine as well.
IMHO it's very, very hard to beat the sound you can get out of these speakers for the price they go for used now, if you like an accurate/truthful sound. Although you do need to factor in the cost of a powerful amp to get the very best out of them.
