The best speaker you ever heard?

WITH NO DOUBT,Vocal and dynamic thar are extremly rare in all price rate...
Look amazing also.
IF own them u stay with them!

I may have answered this before but only a few ever really caught my attention: (call it a tie as I can't choose just one set)
1)Beveridge SW2
2)Magnepan typani Id
3)Hill Plamatronic
4)Apogee duetta signature
5)Dayton Wright XG-8 (with leaf tweeter and upgraded step up transformer)

55dok, I may be mistaken but only some of the Dayton Wright XG-10 Mk IIs have leaf tweeters. That's what mine are. They have the XIM-11 interface module which I think is what you are referring to as well - it puts out 15 kV bias voltage instead of the XIM-10's 9 kV, raising sensitivity by 4 to 5 dB.

amazing!

Sunlight engineering SE 308, 2 way 18in concentric drivers.In my large BR cabinets they fill large rooms with even SPL. Image stays centered even when far off axis. Midrange is so detailed, I hear things in music I know well that I have not before. They have a musical connection that seems to go beyound fidelity into musicality, touch your soul, bring out the emotion in music. Built to last a lifetime, magnets are 50lbs ea of alnico.Cones are easy to repair. They do need help with sub bass and ultrasonic trebile after all at 103db for a 18in something has to be given up ;) but adding a fostex t90aex tweeter and designing a sub wasent so hard. This system is design for use with a powered subwoofer I use a aura 18in monster fills in below 50hz. Together this near 800lbs Sat sub system can fill very large spaces on lower power ampliiers , se308 mains are 103db 8ohm drivers are costly near $10000 pair just for se308,one would still need cabinets crossovers etc. Still one of the best I have heard owned.
