I've owned them for six months. Generous output power, superb sound, only 42 lb. and slim covers. Lows, mids and highs are aggressive but not harsh.
I tested Behringer's B215A, Mackie (very good but more expensive for only 12"), HK (good but more expensive and heavy), EV (great but much too expensive for me).
Excellent, 10/10 for concert PA systems.
