Revolution Design Audio Alpha


The RD Audio Alpha Series subwoofer line. The Alphas were designed to be very versatile subwoofers. They can put out very high SPL while still sounding great and they can go toe to toe with anything out there in its respective class. These drivers perform great in the mid bass range and will extend quite low when coupled with the car's cabin gain.

If you want loud bass but also want it to sound great at the same time then these drivers are for you!

Some features common to the 12" and 15" models:

  • 2000 Watt Subwoofers
  • Rigid Chrome die cast aluminum 12 spoke basket
  • Organic long fiber non-pressed cone body
  • Highly damped Kevlar reinforced cone body
  • Three layer foam surround
  • Extended neck joints on cone, coil, and spider to strengthen the integrity of the moving structure for high power
  • Vented three inch high temp aluminum voice coil
  • Vented gap technology
  • Low carbon steel front and back plate
  • Powerful dual stacked 90 oz magnets
  • Reinforced resign impregnated polycotton spider with integrated heavy duty tinsel leads
  • 2 inch long excursion motor structure
