The best speaker you ever heard?

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.

The Orion loudspeaker from linkwitz labs has to be one of the greatest speakers ever made.I have heard many many of the highly regarded speakers. I have heard most of the top and current models( Merlin,B+W,Focal,Martin logan,Totem,Gallo etc etc) but the orion is the finest I know of.No speaker is perfect but man this one puts you substantially closer to live music than any other I have heard.

Loki1957 - I also have the Hales C-5. I will never sell them! One of these days I'm going to give them the power they deserve... I'm sure it will be a whole new experience.

..... and the rockport technologies hyperions, which i now so proudly & enjoyably own!

I haven't been exposed to much, but the best system I've heard was 3 channel set-up using Dahlquist DQ-20s in 1990 or so. The guy had put together a comparator that took the information that was common to both channels and put that in a center channel. It wasn't a "surround sound" processor, either. Around that time I also heard some Acoustats that sent me down the path of ESLs, I'd say those were the most dramatic speakers I've heard with regard to the life-changing impact they had on me.

The best speakers I've ever heard are the Sequels I get to listen to every day! :)
