Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide excellent heat dissipation. Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions.
CEA-2031
Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. This means your speaker has the capacity to handle power under continuous damand, not instantaneous power handling, that over time, can damage voice coils.
Reversible Mounting
Rockford Fosgate subwoofers can be mounted in either direction. A removable trim ring can be installed on the back or front side of the subwoofer frame. This gives the subwoofer a finished look regardless of mounting configuration.
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.
Venturi-Effect Cooling
The "Venturi-Effect" is created by gradually reducing the air-flow exhaust path area, which increases the air speed across the key thermal masses ofthe speaker motor parts maximizing cooling effectiveness.

Thirty Years of Rockford Fosgate Rockford Fosgate products have been designed and engineered in Tempe, Arizona since the beginning. Rockford's 30 year reputation is grounded in engineering and manufacturing some of the finest audio products in the world. The company's no-compromise approach has yielded patented iconic products such as the Punch EQ, Punch 45 amplifier and the 3Sixty integrated signal processor. Today, Rockford's new products push the performance envelope even further. Each new product is a step forward--they sound bigger, they play louder, and run longer. Rockford never settles for "good enough." The 2010 product line represents the company's core philosophy. Rockfords new amplifiers, speakers and subwoofers have raised the bar on the competition.

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.
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 damand, not instantaneous power handling, that over time, can damage voice coils.
Reversible Mounting
Rockford Fosgate subwoofers can be mounted in either direction. A removable trim ring can be installed on the back or front side of the subwoofer frame. This gives the subwoofer a finished look regardless of mounting configuration.
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.
Tall Profile Surround
The use of Tall Profile high excursion poly-etherester Surrounds, subwoofers exhibit maximum linear travel characteristics without reducing overall piston size.
The use of Tall Profile Surround, in conjuction with maximum piston area yields the highest SPL possible.
Venturi-Effect Cooling
The "Venturi-Effect" is created by gradually reducing the air-flow exhaust path area, which increases the air speed across the key thermal masses ofthe speaker motor parts maximizing cooling effectiveness.
The benefit of the "Venturi-Effect" is the reduction of voice coil temperatures, substantially improving thermal dissipation, and improving overall reliability.
