How to choose
Choose single or dual driver cabinets based on the room size and how much low end the gig actually needs.
Beginner
Someone adding their first sub to a small rig should start with a single 15 or 18 inch cabinet such as the Wharfedale Delta X18B or Hybrid LB15 MKIII. Keep the sub on the floor rather than stacked until you are confident with cable runs and amp settings.
Intermediate
A user running regular gigs in mid-size venues should look at the Wharfedale EVO-X18B or Yamaha CW115V for a step up in output while staying practical to transport. Check polarity between subs and top speakers to avoid cancelling bass in parts of the room.
Expert
An experienced engineer covering larger events should consider dual driver options like the Hybrid PLUS PK218 or Wharfedale EVO-X218B for maximum low-end output from fewer boxes. Plan sub placement and array spacing to control coverage, and monitor amp temperatures during long shows.

About Passive Subwoofers
A passive subwoofer adds low-end punch to a PA rig but relies on an external amp to drive it, giving the user control over how much power reaches the low end. This makes it easy to scale a rig up by adding more subs without changing the tops.
This page runs from single 15 and 18 inch boxes to dual 18 inch cabinets like the Wharfedale Impact X218B and Delta X 218, with the Hybrid PLUS range and Yamaha CW115V also available.
