JL Audio CR-1
Active crossover
What it is
crossover_role: sub_mains_bass_mgmt — the audiophile benchmark for two-channel subwoofer integration. "Designed by audiophiles, for audiophiles" (JL marketing); widely regarded as the reference analogue sub/mains crossover.
Managed Bass Input (bypass) allows 2-ch + multichannel coexistence — not relevant to this vinyl-only framework but confirms a clean analogue path.
