ST-EQ-180

Multi-Band Audio Shaping & Sound Precision Control

The SoundXtreme ST-EQ-180 is a 7-band stereo graphic equalizer designed to give users precise control over their vehicle’s sound profile. With adjustable frequency bands ranging from deep bass to ultra-high treble, it allows fine-tuning of audio output for a more balanced and personalized listening experience.

Each slider independently adjusts key frequency ranges, helping correct weak factory tuning, enhance vocal clarity, or boost bass response depending on your preference.

Built-In Fader & Subwoofer Control Integration

This equalizer includes integrated fader control, allowing seamless adjustment between front and rear speaker balance. It also features subwoofer crossover functionality, giving you control over low-frequency routing for cleaner and more controlled bass output.

With selectable subwoofer switching and crossover points, it helps integrate subs more effectively into your overall system while reducing distortion and overlap between frequency ranges.

Clean Signal Handling & System Optimization

Designed for stable signal processing, the ST-EQ-180 maintains a wide frequency response from 20Hz to 20kHz, ensuring full-range audio integrity. Its low-noise circuit design helps preserve clarity while making adjustments across all seven bands.

The unit is optimized for aftermarket and OEM systems, improving overall sound staging, imaging, and tonal balance without introducing significant distortion or signal loss.
