Featuring innovative parabolic cone designs, oversized surrounds and large motor assemblies, Power subwoofers deliver deep, loud, aggressive bass…not to mention stunning cosmetics that you’ll want to show off. For over 20 years, Power subwoofers have shown the world that big bass, extended power handling and awesome cosmetics need not cost a fortune. The Power Series subwoofers build on innovative new Rockford Fosgate technologies. These bad boys have patented VAST technology that increases surface cone area up to 25%. The new FlexFit basket not only looks the part but it provides extreme flexibility for extreme installations. Clean, high tech and ready to set off car alarms, the POWER sub is here! Anodized Aluminum Voice Coil Former Two things generally happen when voice coils heat-up.
- They can generate heat close to the melt-down temp of their adhesive bonds which leads to eventual failure.
- Voice coil dc resistance increases and reduces SPL output.
Solution… Rockford Fosgate subwoofers use aluminum formers or voice coils for their excellent heat dissipation and SPL capabilities unlike many other plastic substitutes. VAST Surround Acronym: Vertical Attach Surround Technique VAST™ significantly increases a speakers effective radiating cone area without complicated installation issues. This design alters the typical design and manufacturing technique by eliminating the large flat glue surface area (the landing) which allows the surround to be shifted for increased cone area. In turn, both nominal efficiency and maximum output capabilities are dramatically improved. Flex Fit Basket The Flex Fit frame utilizes slots (where feasible) instead of single screw sized holes. This allows slight adjustment of the speaker when mounted. Stitched Tinsel Leads Multipoint “periodic” stitched lead wire technique reduces the mass of each tinsel lead and spreads stress and strain over a greater area, significantly improving the reliability and performance of the subwoofer. These stitched tinsel leads withstand extreme duty cycles, fatigue and high current that is critical to robust design. IDHS™ Inductive Damping Heat Sink Acronym: Inductive Damping Heat Sink Secures directly to the top of magnet structure to improve system efficiency by reducing both distortion and back EMF (Electo-magnetic force). Also radiates heat to reduce voice coil temperature. SWIFT™ Terminals Acronym: Selectable Woofer Impedance Fused Termination Removing and inverting the centre plug, a Series or Parallel wiring configuration is accomplished. The removable impedance selection jumper also provides fused protection in severe overload conditions. CEA-2031 Compliant Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. This means your speaker has the capacity to handle power under continuous demand, not instantaneous power handling, that over time, can damage voice coils.
