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


Not the most expensive, not the best reviewed, not the biggest, but the most FUN.  You know, that ONE that just makes you throw on some more music and keep listening, the one that makes your toes tap, your head bob, your ass move the most.  The one that makes you think to yourself "damn, why doesn't everyone have a pair of these?" Let 'er rip.

RCA Photophone horn system ran a pair for 10 years sold them but bought another since I missed them so. 
The used pair of 1977 Klipsch Cornwall I systems were utilized for program material playback. Also, these were utilized with "live" performance of electronic keyboard performances. Efficiency and moderate performance linearity were the reasons for "fun" value.
First generation Reel to Reel Designs Legacy Classics were "fun" being a listening experience reward. The floor standing subwoofer was culminated with perfection components, design engineering, and components. 
A music store instrument trade in yielded acquisition of new pair JBL 4412A Professional Series speaker systems. Part of the fun was the 4412A's in effect cost only $400.00. Later, a recording studio desired the 4412A pair. The good value status transpired to the Studio sale.
The Epicure 100 bookshelf system pair were a "fun" backup system. I owned them for 35 years. Their sonority contrasted any other systems owned. Moderate efficiency and 90% linearity yielded "stellar" low volume listening. The "fun" go to listening "rivaled" friends systems from the college dorm era.
