Skar Audio VX175-ST 1.75" Aluminum Bullet Super Tweeters

The Skar Audio VX175-ST are 1.75-inch high-compression aluminum bullet super tweeters that deliver focused, ultra-clear high frequencies with 400W peak (pair) power handling for crisp detail in car audio systems.

Built to reproduce the top end of a mix with precision and impact, these VX175-ST tweeters combine a compact high-compression aluminum bullet design with a high-temperature Kermet (Kempton) voice coil and high sensitivity. They’re tuned to extend response from about 2.8 kHz up to 20 kHz, making them a practical upgrade for enthusiasts who want improved clarity, imaging, and stage height without sacrificing power handling.

How will these super tweeters change my system’s high-frequency detail?

These tweeters emphasize upper harmonics and fine transients, delivering clearer cymbals, vocals’ air, and subtle synth textures. The high-compression bullet shape focuses output for better projection and imaging, while 99 dB sensitivity helps them integrate with modest amplifier power.

• Tight, directional high-frequency projection for improved stereo imaging
• 99 dB sensitivity requires less amplifier power for audible output
• 2.8 kHz–20 kHz range enhances presence and detail without fatiguing midrange

Are they durable enough for car audio use?

Yes — the VX175-ST uses an aluminum bullet and a 1" high-temperature Kempton voice coil built to handle heat and sustained power. The tweeters’ materials and construction are chosen to tolerate the thermal demands of vehicle audio systems and maintain consistent performance.

• Aluminum bullet housing resists deformation and keeps resonance controlled
• High-temp voice coil reduces thermal compression and distortion during extended listening
• 4-ohm impedance matches common car amplifier channels for reliable operation

How much power do these tweeters need and how should I set crossover points?

The VX175-ST pair can handle up to 400W peak and 200W RMS, giving a healthy headroom margin for most car audio systems. Because they’re high-compression tweeters, plan a crossover that hands off frequencies cleanly around the lower end of their response to protect them and ensure balanced integration with midrange drivers.

• Peak power (pair): 400W; RMS power (pair): 200W
• Recommended crossover: set lower cutoff near 2.8–3.5 kHz to protect tweeter and smooth blend
• Use appropriate attenuation or filters if amplifier output exceeds RMS ratings

What mounting and system roles work best for the VX175-ST?

These compact super tweeters are ideal for surface-mounting on dash panels, A-pillars, or custom pods where directivity and stage elevation matter. They’re frequently used as additions to component systems to lift the high-frequency image and add sparkle without replacing existing midrange or woofer components.

• Surface-mount pods, custom A-pillar installs, or dash placements for improved imaging
• Works as a complement to component speakers or coaxials to enhance top-end clarity
• Includes a user manual to guide wiring and basic mounting considerations

Who is this for? The Skar Audio VX175-ST tweeters are aimed at car audio enthusiasts and installers seeking a compact, high-output solution to sharpen highs and improve stereo imaging. Choose these if you want a focused, high-sensitivity tweeter to pair with component speakers or to add air and detail to factory systems — especially when space is limited but high-frequency performance is a priority.
