Summary: Really disappointed about Mackie. I guess this it's always true that "if it seems too good to be true, it probably is". When I read the specs I thought it was a great price for a 400W Mackie, even lower price than some Behringer's so, the purchase seemed like a no-brainer.
Summary: Quit working after 6 months. No power. These things were not worked very hard. They sound ok but, now I have trust issues. This will be the last Mackie product I will buy. Engineered in USA. Built in China.
Summary: This thing craped out after 9 months use as my electronic drum monitor... Never moved or left home... I own an old pair Mackie srm 450s that still sound great after hundreds of gigs... Buy this Thump series at your own risk!
Summary: Not super loud (their SRM-450 is much louder), but great sound quality. I adored this speaker, right up until until it broke. I was running it hard on a hot day and the internal amplifier blew, despite all of the advertised protection features.
Summary: I got this dude slightly used and so far so good. It is well built and it comes with a good lengthy power supply. For a second hand powered speaker, I think the Mackie Thump-12A 400-Watt have met my expectations.
Summary: I haven't had any issues with reliability, as such, but to call these "400 watts" is a joke. At line level, you can barely hear anything, and even using a mixer to boost the signal: not loud enough to complete with even the tamest of drummers.
Summary: I read reviews on this speaker pryor to purchasing a pair. These speakers are great for the money and perform very well in small to medium venues. I read several reviews about these speakers not sounding as good as more expessive speakers and about the bass response.
