CT Sounds TX-175B 1.75” Neodymium Super Tweeters – Pair, 480W Max, 105 dB

Elevate your high-end clarity

The CT Sounds TX-175B is a compact, neodymium-based super tweeter pair designed to bring airy treble and detailed sibilance to your existing car audio setup. Each unit is a 1.75” 4-ohm design that can handle up to 120W RMS per tweeter (240W RMS per pair) and up to 480W MAX, delivering controlled highs with minimal fatigue. The neodymium magnet system helps keep the hardware lightweight while preserving strong output at the upper end of the spectrum.

With a sensitivity rating of 105 dB, these tweeters are built to produce clear highs with less amplifier demand, allowing your source material to shine without overwhelming the rest of the system. The frequency range spans from 3 kHz to 20 kHz, which means you can expect crisp air, sparkle on cymbals, and enhanced vocal sheen when paired with midrange drivers and woofers.

Why this pair makes sense

• 1.75” single 4-ohm configuration, sold as a pair for balanced stereo imaging.
• High sensitivity supports dynamic, clean highs without excessive power.
• Wide frequency reach up to 20 kHz for added airiness and detail.
• Cross-compatibility with standard car audio systems thanks to 5 kHz recommended high-pass crossover.

The TX-175B ships with wires and pre-installed capacitors, enabling a smoother install and signal shaping right out of the box. This means fewer aftermarket parts to source and an easier path to a cleaner high-end response.

Real-world use cases

• Smooth, extended highs for rock, pop, and acoustic genres, with clearer vocal articulation.
• Compact footprint makes it feasible to mount in constrained dash or door locations without crowding other components.
• Ideal for upgrading factory tweeters where brightness and width of the treble need more presence.

Whether you’re tuning a daily driver or building a more spirited listening setup, the TX-175B offers a practical path to more refined treble. It’s important to pair these tweeters with compatible crossovers and midrange components to achieve a cohesive sound stage. While performance varies by vehicle and head unit, many users report noticeable improvements in high-frequency clarity and instrument separation when integrated thoughtfully into the system.
