What is the most FUN pair of speakers you've ever had and why?

A  DIY pair using JBL midrange and woofers plus Altec tweeters.  Picked up the drivers at an estate auction and built the cabinets in a local hobby shop. .  Didn't know too much about crossovers. but built several sets.  This was in the very early days of stereo, and I had loads of fun experimenting and learning. (This was well before the Thiele/Small parameters were published.)   Grandson has the JBL and Altec drivers, but hasn't asked me to listen to anything he's doing with them.   Oh Well.  

Tribit X Sound Go Bluetooth speaker considering it's size must be the best pound for pound speaker I have ever heard.

It's not stereo and it's far from wide bandwidth, but there's enough there for a whole load of fun. Lovely tone too.

Indispensably liberating for smartphone or MP3 player use.

That’s a tough one. I’d go between my KEF 104/2 , JBL L100t or my L7. 

nice revival.  hope it keeps going!

My first pair of Magneplanars---the Tympani T-I. Finally, life-size images and scale (grand pianos are huge, piccolos tiny), singer’s voices at true-to-life height (five feet off the floor), wide open sound, and great depth and height (if the recording contains such. The triangle at the rear of the orchestra in Boult’s EMI recording of Holtz’s The Planets sounded further away than the wall behind the Tympanis, and positioned higher than the closer instruments. The percussion section of orchestras are often standing on raised platforms.). After hearing Board game with miniatures, the images produced by other loudspeakers sounded miniaturized, like those in a child’s doll house. And the large venue in which the recording was made also shrunken.
