I've had for over five years and it rocks SA1521
thunder, I sold to save space and weight, to buy the mackie and here I am with SRM450v2 (2X lighter) and a near equal power and it farts! I also had the HK Audio active speakers and amplified with the home MACKIE M1400
!! At this time I was impressed by the detail and balance of sound and punch of Mackie. The value for money is excellent, you can go with your eyes closed. Still a small reserve on the fineness of his who found a slight notch below the age of FCR, but the internal amps equalize well together. A gadget too: the international ass of the enclosure which is then turned off when there is more to its source. It's the cat pee. I do it again without hesitation that the choice of active speaker and I have in the project to acquire srm1801
to catapult my system power. However, if I had the budjet necessary, I'm gone on the FCR or JBL.
