I used to have a pair. Honestly, I wish I still had them. I used to use a pair of powered 10" JBL G2 Eons for my mains (and had some B52 tops as backups). Sold the B52s and bought the Mackies for backup. Well, I liked the sound out of the Mackies better, so used them more often as my mains than I did my JBLs. They would clip fairly easy, but I also used them with a pair of subs most of the time and they would get pretty loud without clipping when using subs. The times I didn't use a sub (which is why I still wish I had them now) was for my own personal backyard parties and football tailgates that didn't require a crap ton of volume. They had a LOT of bass for a cab. In hindsight, I would of sold my JBLs honestly. I liked how small and convenient the JBLs are for a ceremony or the small space it takes up for storage and traveling to gigs, but...I liked the amount of bass I got out of them for a more full sound without lugging around my LS801p, or my 15's.
With that said, I sold the Mackies when I bought my RCF ART-312As. The RCFs...BLOW all those speakers out of the water. They don't have the bass that the Thumps did, but I didn't expect them to. I have a pair of cheap powered 15's that I use when we tailgate or have a little get together and need some audio. It's slightly more work, but better than having no bass or lugging around the Yorkville.
Anyway, point being...I never had a reliability problem, sounded pretty good for the money, light weight, lots of bass, personally I think they were good looking speakers...I'd own them again. Don't expect to do any kind of crazy sized gig though. There are definitely some applications though that they are AWESOME speakers, in MY opinion.
