“The three ‘L’s’ are the driving force behind Paradigm’s subwoofer research … Louder, Lower-Frequency, Lower-Distortion bass.”

– Paradigm Design Team

High-end gear has a reputation for being outrageously priced, but don’t be fooled. Sometimes, even the priciest gear delivers performance that is nothing to write home about. Today, more than ever, the Price-to-Performance ratio of a product must remain top of mind—and that’s where Paradigm shines; why we have been voted #1 for

19 years*. Our SUB 12 and SUB 15 are perfect examples …

A natural evolution in our lineup of award-winning subwoofers, they benefit from our years of research into the mechanics of producing louder, lower-frequency, lowerdistortion bass.In fact,the three ‘L’s’ are the driving force behind our ongoing commitment to refining and improving the performance of our subwoofers.

The unique amplifier/driver configuration in SUB 12 and SUB 15 allows these subs to play louder and lower than any other subwoofers in this price range, and still cost less! And unlike many designs on the market, not a hint of low-frequency extension or output was sacrificed to keep their size compatible with today’s living spaces.A comprehensive range of input and control facilities make setting up the subwoofers a snap.

Finally, since the room itself (dimensions, dead spots, archways, even furniture!) can have a dramatic impact when even the finest subwoofers are perfectly positioned, Paradigm also offers a solution for the problems of the room! SUB 12 and SUB 15 are designed to be used with the critically acclaimed Paradigm® Perfect Bass Kit** (PBK-1) which adjusts for the room’s negative effects on a subwoofer.
