    Product details:

    The HELIX CB C100.2-S3 is the entry point into the COMPOSE BASIC range, built around Audiotec Fischer's efficient 3Ω design so it drives hard even from modest head-unit power or a compact amplifier channel. A lightweight injected-polypropylene midrange cone keeps mid-bass tight and controlled, while the neodymium silk-dome tweeter adds smooth, extended top end without harshness. Its shallow 48.9mm installation depth and compact 99.2mm outer diameter make it a straightforward factory-fit upgrade in tight door cavities.
