    Product details:

    The HELIX CB C87.2-S3 is the smallest speaker in the COMPOSE BASIC family, purpose-built for the shallow 3.5-inch dash and rear-deck locations found in many factory installs. A lightweight PEI-dome tweeter with neodymium magnet delivers crisp treble from a compact footprint, while the polypropylene midrange driver still runs the efficient 3Ω COMPOSE BASIC design. At just 42mm deep, it fits where larger drivers can't.
