Haraldo, Mackie is known for their professional gear and make their equipment to exacting standards. They make everything frrom mixing tables to concert venue speakers, but music companies were so impressed swith what they had done to the live music industry that they hired them to create a speaker that would be ruler flat in frequency response for engineers to mix the music. Hence the H824 Studio Monitor was born, although not known to the general public who shop for Bose and Klipsch, those in the know and professionals use the H824's because they are that good. I have spent only a few hours with them at a GTG in Texas last year and fell immediatly in l,ove with how well it produced the sound without the use of a subwoofer, the sound was just clean and pristine.
