This passive design maintains the character of your source while providing up to ±12 dB of boost\/cut at seven musical center frequencies. Built for inline use in car audio or compact rigs, it includes a selectable subwoofer crossover and level\/fader adjustments so you can tune balance and low-end response from the dash or rack.\u003c\/p\u003e\n\n\u003ch3\u003eHow will the seven bands change my system’s sound?\u003c\/h3\u003e\n\u003cp\u003eEach slider targets a defined center frequency so you can attenuate or accentuate specific tonal areas — from deep bass to shimmering highs.
