I own them for 8 months
I have also LD 152A systems that are much better and a pair of opera DB 405 which are both superior sound and does not heat up after 4 hours
The Mackies are screaming and fragile. for that price there are better on the other hand, RCF, dB Technologies, LD systems.
They were made for parallel with behringer for about 120 people and the behringer sounded better and did not heat them, is to say
Nevermore these mackie
For cons, I have the Mackie mixer and is the ultimate in precision, sound, durability, usability
