HELIX Ci3 W200FM-S3 COMPOSE i3 8" Performance Woofer 3 Ohm

Quick answer

The HELIX Ci3 W200FM-S3 is an 8 inch 3 ohm woofer from the COMPOSE i3 range, rated at 100W RMS and 150W peak.

It is shallow at 63.7 mm, so it goes into many factory 8 inch door spots, and the 3 ohm load pulls a little more power from an amplifier than a 4 ohm driver.

Problems it solves

• Thin midbass from factory 8 inch woofers. 94 dB at 2.83V gives real punch.
• Doors with little depth. Mounting depth is just 63.7 mm.
• Odd factory mounts. A universal ring with grille is supplied for each woofer.
