i hear the "new" Yamaha DXR line is AWESOME...
and many prefer over the QSC K's
i have the HPR12's, plus a pair of 181W subs

as far as the Yamaha's i have not heard them but was gonna buy 1 10" for monitors, and/or speech only function

i LOVE that 3 channel mixer on the back of Yamaha,
makes them quite versatile

i guess i'll wait for these new QSC maybe the 8"
and compare to Yamaha's DXR 8" or 10",
probably the DXR 10" as the 8" cannot be wedged :-)
