Hi Scott......I can't comment on the Roland MA8 or 12 for that matter, however I can state with my honest opinion that the Behringer MS16's are GREAT....the sound if fantastic...they are lightweight and small but pack a BIG punch....and the price difference is an added bonus....I've used mine with both the T1 and T2...I bought mine last year for a total of about $60 w/shipping....here is the link http://www.synthzone.com/ubbs/Forum37/HTML/014803.html Scott, you can't go wrong with these speakers......enjoy.
