I would say you got an ok deal, not the most compact rig but powerful and ok quality.
Gonna be very heavy is your not using it for another install thou.
Need to make sure you set up correct to get most from amps etc.
EAW can be run with a passive or bi-ampified mf-hf crossover.
Need to set limiter correctly to stop speakers getting blown.
