well isnt that what a sub is for? i just want something that will sound amazing i like very full sound. something very warm. not peaky. how would this compared to B & w or def techStereophile has reviews on the Jade 3 and the Jade 7, both very positive. But if you look at the bass specs, these speakers don't go exceptionally deep. However, how deep the go it not related to how well they sound. As I said, the Stereophile reviews were very positive.
Wharfedale Jade 3 Review -

Wharfedale Jade 5 Specs -
42hz at -3db, which implies about 35hz at -6db.
Expect good sound quality, expect good bass, just don't expect especially deep bass.
