Hello jason j
Believe it or not after buying my Yamaha/cinepro
i connected everything and for 10 years never had to touch ANYTHING/NOTHING (well maybe the Volume)
anyway these speakers have there own X-over and i can connect to the ribbons or the woofer or both using a jumper
HELLO GONK
Do you think they would sound better or worse
connecting the woofers to the 990 sub outs
Again thank You Guyzzzz
