£ 840

It's got a great sense of agility and definition, but we can't recommend this Dynaudio because the price doesn't match the look and finish

£ 330

Large, and substantial, Klipsch's SW-450 subwoofer has the power, but we found that it lost its way when faced with complexity

£ 400

It might not have the serious punch of some other subwoofers on the market, but AE's Neo v2 makes up for quantity with amazing quality

£ 445

A cracking subwoofer – Velodyne’s strongest budget offering in ages

£ 1250

It's small and stylish and we think Paradigm's Seismic 110's a sure-fire winner - if only it could get past B&W's all-mighty PV-1

£ 225

Capable little subwoofer that will help systems needing encouragement in the lower frequencies

£ 500

This sub may be a touch bass-light, but otherwise it does a fine job

£ 300

Wharfedale's Diamond 10.MX is hard-hitting but not mindlessly so

£ 1000

This accomplished subwoofer full deserves each of its five stars and should be firmly on your audition list

£ 600

Impressive in some areas, but for this sort of money we'd expect performance to be a bit better
