About this item

Product details

Powered 12" Pro Audio/ DJ Subwoofer Cabinet Over the last 20 years, Seismic Audio has become synonymous with high-quality and affordability in Pro Audio and DJ Gear. Our Subwoofer Cabinets have always been best sellers and received high praise for their ground-shaking bass performance. We are pretty sure we outdid ourselves this time! Introducing the Shockwave series of PA/DJ Subwoofers. Once you hear these, you will agree that we could not have picked a better name for this line of subs. Deep, punchy and low-end bass unlike any other subwoofer we offer in 12 or 15 inch models. This is a high performance, compact 12" Powered subwoofer with a Class D Amplifier. The Shockwave series was designed with medium to smaller live sound and DJ venues in mind. Do not let the compact size mislead you! Make sure pictures are secure and that nothing is close to the edge of a table. These subs will move furniture with its deep bass reproduction. These hit so hard, if you are standing in front of it, your heart may skip a beat and you will swear it is more than a 12 or 15 inch sub!

Shockwave 12-in

I bought this sub for a drum monitor so my wooden shell acoustic drum can compete in an amplified world so I can actually hear and feel my kick drum above loud bass/guitar amps-- I should have done this a long time ago! I can now just relax and play and I don't have to stomp real hard on the Bass drum just to hear it! so I can play more relaxed and not hurt myself. I haven't had it very long but I'm very pleased with it so far. ! Ordering was easy and shipping was fast, thanks!
