What's your dream speaker?

If my listening area was a dedicated room I would probably still have Accoustat 2+2s, but in a room that is multipurpose their height cut the room up (bad feng shui). I also had Maggie 3.4Rs, but the visual issue was very similar, also the lack of seamless integration between the ribbons and bass panels was no bueno. I now have Emerald Physics 3.4s (12" concentric driver with 1" polyester tweeter), and while amazing, my room is quite large and the reinforcing back wall is ~ 25 feet behind the speaker faces and it's all glass, essentially no reinforcement. I have 2 @ ~ 10+ yo SVS powered subs, which were not designed for 2 channel, but have made do.

Soon the 3.4s and subs will be replaced with EP 2.8s, which is the 3.4s + 2 @ 15" carbon fiber woofers

JBL 4367 4349 or 100L Classic 75th Anniversary
Whichever 1 of these i can afford in the next fee years... 

For me in the mid/later 70's and early 80's it was the Magnaplaner Tympani I's and the JBL L-212's.

One of the best moves I have ever made as an audiophile - this will apply to a certain percentage of frustrated hobbyists - was to abandon the search for "the One", the purported speaker that would sound perfect, and seek variety. I have found delight in the speakers of different genres I have used. Audiophilia was fraught with frustration until I made variety the key of my system building.

I've gone the same route.  Having more than one speaker to switch in tends to scratch the itch for change, and when listening to one I'm not "worried" about the characteristics it doesn't have that another speaker has...because I have that other speaker too :-)

Not saying that ultimately The One wouldn't be nice.  But I think I had to admit after many years I'm always going to get the itch for new sound.

Right now (among other speakers) I have probably my two favorite "sounds" - Thiel and Joseph Audio speakers.  I'm thinking if I had one more trophy it would be one of the Devore O series speakers, then I'd have my 3 favorite speaker brands and be spoiled as heck.

flea watt amps. Horns for bass are larger than my space can accommodate so must determine compromises I'm willing to settle for.

I'll never own a   hifi horn setup,,so I have settled for next best thing with my WBer W8+W4 system 
My dream did come true.
