• Round aluminum windings: Offer stable electromagnetic characteristics and consistent voice coil behavior across heavy use.
• Dual 2 ohm configuration: Lets installers preserve wiring options and impedance choices for multi-sub setups or existing crossovers.
• High RMS power handling: Rated for 1200W+ continuous capability, giving a margin for demanding audio systems and higher gain settings.
• Model compatibility: Fits specific Type R part numbers SWR-1043D, SWR-1243D, SWR-1542D and functions as an upgrade for SWR-1541D.

Who It's For

This voice coil is aimed at installers, DIY repairers, and experienced car audio enthusiasts who need a dependable aftermarket replacement for Alpine Type R subwoofers that require a 2.5' coil. It is especially useful when the original coil is damaged by voice coil rubbing, overheating, or when seeking a like-for-like high-RMS replacement without modifying the enclosure or motor assembly.

It is not targeted at casual buyers looking for a plug-and-play aesthetic match to OEM cosmetic parts or those who lack soldering and speaker reassembly experience. Novice users without workshop tools or experience with speaker rebuilding should consult a technician or shop that does coil repairs.

Pros & Cons

Pros

Frequently Asked Questions

Will this fit my Alpine Type R sub?
If your sub uses a 2.5' voice coil and is one of the listed models (SWR-1043D, SWR-1243D, SWR-1542D) or the SWR-1541D upgrade, this coil is designed to fit without major modification.

Is this an original Alpine part?
No, this is a custom-made aftermarket voice coil designed as a replacement rather than an OEM component, so cosmetics and packaging differ from factory parts.

Do I need special tools to install it?
Yes, installation requires speaker disassembly, soldering or connector work, and careful reassembly; a shop or experienced DIYer is recommended if you lack those skills.
