These 15" subwoofers outperform many 18" boxes in both loudness and depth, yet stay tight and punchy, due to a 15" construction, similar to having a race car that can still carry a lot of weight like a truck.
 
Every professional or loudspeaker engineer will vouch for the Italian B&C components. Hosted in a matched reflex enclosure, these loudspeakers deliver a fast, punchy sound. Bass notes will be distinguishable and have minimal unwanted resonance. These are fantastic for non-ideal acoustic environments.
