My Yamaha only is 7.1 out...(Yeah I'm using that as an excuse not too purchase another sub

) . However, two subs that will give me solid 20 Hz extension will still cost me around $1000. for the pair. I was hoping that Emotiva for $535 delivered to my front door was the ticket but it wasn't. Oh, well, scrimp save, start eating kleenex, anythiing,

to build my savings account up to get a good sub.
