Looking for sub advice.
Focal chorus 814 mains
focal center
Yamaha rx v673
50/50 movie music split
Room size:24wx20dx8h carpet
speakers will be on the 24ft wall,12ft off it is wall 12 ft is open to the rest of house.
Im wondering if I need a ported or sealed sub.Someone on another thread mentioned svs 12 sealed sub.Did some research and it "appears"its meant for a small room.Where ported are meant for larger rooms.
Any advice on a sub for my setup? Ive heard svs and Outlaw are good?l
Id "like" a sub in the $1300 range.But Dont have the dough,so looking for something in that range used I could get for less.I need some ideas to start looking up craigslist Ebay ETC..Im in no rush and can wait till something pops up.
Noob with no idea what to look for

Thanks
