    Product details:

    The HELIX CB K165.2-S3 takes the COMPOSE BASIC platform's 6.5-inch midbass — housed in a sturdy, ventilated steel basket for better cooling — and pairs it with a 20mm silk-dome tweeter on a separate crossover, giving cleaner imaging and more tuning flexibility than a coaxial equivalent. A 12dB tweeter slope with 4-stage level adjustment and built-in protection rounds out the crossover, and FlexMount20 compatibility keeps tweeter installation simple.
