Passive Tweeter Crossover 1-Way with PTC, Bass Blockers for Car Speaker, High Pass Filter 2400Hz 12dB/Oct, Treble Audio Frequency Divider with Insulated Sleeve 40W, 4-8 Ohm Pair T-5A

Passive Tweeter Crossover for Car Audio and DIY Speakers This 1-way passive tweeter crossover pair is designed to filter low frequencies and deliver clean high-frequency signals to tweeters. It is commonly used in car audio upgrades, DIY speaker builds, and home audio systems where dedicated tweeter protection and frequency division are required. Key Features Three-Component Crossover Design Uses the inductor, audio-grade capacitor, and PTC resettable protector to create a stable high-pass filter network for tweeters. PTC Protection for Tweeters The built-in PTC protector helps interrupt the circuit during abnormal power spikes and automatically resets once safe conditions return. Multiple Models Available T-4 – 2200Hz / 4–6 ohm tweeters T-5A – 2400Hz / 4–8 ohm tweeters T-5B – 2350Hz / 4–8 ohm tweeters Each version supports up to 40W RMS power handling. Compact and Easy Installation Pre-wired leads simplify connection: Red & Black → Amplifier input Blue & Black → Tweeter output The compact 50 × 25 mm board fits easily inside door panels, dashboards, or speaker cabinets.Typical Applications Car audio tweeter upgradeDIY speaker crossover projectsAdding tweeters to existing speaker systemsHome audio speaker buildsPackage Includes 2 × Tweeter Crossover (Left & Right Channel)2 × Insulated Protective Sleeve

• 【HiFi Components】Features inductor + Audio-Grade capacitor + PTC protector. This tweeter crossover delivers much cleaner and more accurate treble than standard single-capacitor bass blockers
• 【Choose the Model】 Select based on your tweeter impedance: T-4 (3.3uF/2200Hz) for 4-6 ohm tweeters; T-5A (2.2uF/2400Hz) and T-5B (2.5uF/2350Hz) for 4-8 ohm tweeters. All handle up to 40W RMS. Perfect for car/home/stage DIY projects. (Sold as a pair)
• 【Easy Installation】 Comes with insulated sleeve to prevent shorts against metal car panels. Clearly marked wires: Black&Red = Input (from amp/head unit); Blue&Black = Output (to tweeter). Compact size (50x25mm) fits easily behind dash or door panels.
• 【Built-in PTC Protection】 The integrated resettable fuse automatically disconnects the circuit during power spikes, safeguarding the tweeters from burnout. No fuse replacement needed – it resets itself once safe conditions return.
• 【Clean High-Pass Filter】 Delivers a sharp cutoff above 2400Hz (12dB/octave), ensuring only crisp, clear treble reaches your tweeters. Eliminates distortion and improves overall sound staging.
