    Product details:

    The HELIX Ci3 C165.2FM-S3 MK2 puts a 165mm midbass and a 20mm tweeter into one coaxial chassis with FlexMount clearance, so it drops into 6.5-inch factory locations without needing extra mounting depth. The updated MK2 cone and voice coil deliver 92dB sensitivity and reach down to 60Hz, giving genuinely useful bass extension for a coaxial driver. It's a practical way to lift factory sound quality without cutting into doors for a full component set.
