How big is "large"?
... I tried to so some research but its seems to be so many variations .. Sealed vs Ported .. 2 smaller subs vs 1 larger sub... passive vs active .. SO im v bit confused where to go with this
The room dimension is 7m (23 feet) x 3.6m (11.8 feet) Height is 3.5m (11.5 feet). ...
In a ~3,175 cu.ft. room, ported would be more ideal than sealed. And active (built-in amp) is more common than passive (external subwoofer amp).
... In terms of budget anything below USD 1500 is fine.
A good single-sub option is the powerful and well-rated Rythmik FV15HP. It'll come in under budget ($1,200 + shipping), but it's a bit large.
If you're OK with sacrificing some bottom end while still getting the quality and punch you want, a good dual-sub option is the HSU ULS-15 MK2 DualDrive. The subs are relatively compact, but the pair come in at just under ~$1,650, shipped.
You could also try a pair of SVS SB-2000s. They're compact and fairly powerful, and a pair will run you ~$1,300, shipped.
