I bought the small Nady 160 watt 4-channel self-contained head and two of the 12" Nady speakers you're looking at for my 13 year old grandson's band. The head was $119.99 and the speakers (300 w capacity) were $69.00
from Musicians friend. Not the greatest quality, but the head has delay and the system sounds great.

I ordered a second head a week later as a back-up and have used it for sa few small jobs. A great value!
