MAIN FEATURES
Protect your midrange clarity and prevent distortion by filtering out damaging low frequencies from your 6.5" speakers. The BB-65 blocks approximately 0–600 Hz at 4 ohms (and 0–300 Hz at 8 ohms), improving overall system balance and safeguarding speakers from bass they weren’t designed to handle.
Key features:
- Frequency blocking (4Ω): 0–600 Hz. Optimized for 6.5" midrange speakers to eliminate unwanted low-end that causes distortion.
- Frequency blocking (8Ω): 0–300 Hz. Ideal when your speakers or crossover network run at 8Ω.
- Power handling: Up to 50 W per blocker. Reliable performance for common OEM and aftermarket door speakers.
- Easy identification: Green color-coded leads to match the 6.5" model and simplify installs.
- Simple install: Encased with wire leads; splice into the positive speaker wire for a clean, fast fit.
SPECIFICATION
