HELIX IK W12 – 12" Dual 2-Ohm Subwoofer

Compact Power. Impactful Performance.

The HELIX IK W12 subwoofer delivers exceptional bass from a compact footprint. Designed for space-efficient enclosures, it’s perfect for tight installations without compromising sound quality. This driver is a standout addition to HELIX’s IMPACT lineup, built to deliver powerful low-end performance even in smaller custom boxes.

Precision-Engineered for Pure Bass

Crafted with a hand-scooped paper cone and a rugged motor structure, the IK W12 handles up to 300W RMS with ease, delivering clean, punchy bass. The advanced double-ventilated voice coil design minimizes compression and ensures thermal stability even at high outputs.
