Product Description
ROCKFORD FOSGATE R2SD4-10 - 4-Ohm Dual Voice Coil, 250 Watts RMS
Car Audio Fanatics who want Rockford Fosgate quality can rely on the Prime Series 10" subwoofers to get the job done, and the Dual Voice Coil provides awesome installation flexibility. These drivers can pump out the bass due to their mica injected polypropylene cone, and their stamp-cast baskets with spider venting - typically reserved for more expensive models - keep the motor running cool! These R2 subwoofers are optimized for sealed and vented enclosures.
Car Audio Fanatics wanting big bass can rely on the Prime R2D4-10 subwoofer. This 10” subwoofer handles 250 Watt RMS and the 4-Ohm Dual Voice Coil design lets you to wire them in various configurations.
- 12 AWG compression terminals
- Anodized aluminum voice coil former
- Optimized for both sealed and vented enclosures
- Mica injected polypropylene cone
- Linear spider with embedded 16 AWG tinsel leads
- StampCast basket with integrated spider venting
- Integrated PVC trim ring
Anodized Aluminum Voice Coil Former
Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide superior heat dissipation (up to 100° at full power levels). 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.
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.
Stitched Tinsel Leads
Improved reliability and performance by reducing fatigue and possible shorting.
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.
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.
