The BB-35 Bass Blockers are passive inline filters designed to protect 3.5-inch car audio speakers from low-frequency damage. By blocking frequencies outside a tweeter or small speaker's capable range, they improve power handling and reduce distortion. Sold as a pair, they install easily without additional hardware.

• Frequency blocking at 8 ohms: Eliminates 0–1,400 Hz for compatible 8-ohm drivers.
• Power handling: Rated to handle up to 50 watts continuously.
• Red color-coded leads: Simplifies polarity identification during installation.
• Encased wire-lead design: No mounting required — installs inline with existing speaker wiring.
• Sold as a pair: Covers both channels in a stereo setup.
