I have MMGs. They are the baby Maggies, but for the money you pay, you'd be hard pressed to find a better speaker. Keep in mind, they are not a speaker for all kinds of music. If you like music like metal or rock that is loud and kicks you in the face, maybe some older JBLs or Cerwin Vegas will work better. The strengths of the speaker are an open musical presentation of sound. Jazz, blues, classical, chamber music, acoustical guitar, sax, piano and vocalists. These are the genres and sounds that allow MMGs to shine. Bass can go low, but it will not present as "authoritative bass".
The ones I have replaced some standmount speakers, and the soundstage really opened up with MMGs. I have run 300wpc of SS power and 38wpc of tube power and they still sounded great.
