I added this sub to my pair of MR524. All that I had to do was to adjust the crossover a bit. It blends so well with the rest of the audio spectrum. I had the krk10s as well the presonus T10 temblor before. I am very happy with what I am hearing out of the MRS10. Looks like Mackie's thought process behind this sub worked out pretty well because you won't see flattering specs w.r.t freq response or wattage but it excelled when it actually came to its performance. Used some Richard Elliot's tracks to tune it and sure enough I am a happy man. I am pretty sure, the sound would open up even more after a bit of burn in. Go for it and you won't regret it.
