Subwoofer Crossover Filter WEAH 90 by Qianson 8-Inch Bass Boost Audio

Description

Product Overview

The Qianson WEAH 90 is a dedicated subwoofer crossover filter designed to enhance low‑frequency response in a variety of audio environments. Built around an 8‑inch dynamic driver, the unit delivers a focused bass boost that enriches music, movies, and gaming soundtracks. The filter operates on a wired 200 W power source, drawing 12 V at 3 A, and presents a 6 Ω impedance that matches common car and home audio amplifiers. Its rectangular prism shape measures 2.28″ D × 3.15″ W × 1.1″ H, making it compact enough to fit discreetly under seats or in console compartments. The touch‑controlled interface replaces traditional knobs, allowing users to adjust bass intensity with a simple tap, while the included 12 V 3 A power supply ensures reliable operation without the need for additional adapters.

Usage

Designed primarily for car audio installations, the WEAH 90 excels in delivering deep, controlled bass in compact vehicle cabins. Whether mounted in a sedan, SUV, or truck, the filter integrates seamlessly with existing speaker systems, connecting via standard wired terminals to the vehicle’s head unit or aftermarket amplifier. Beyond automotive use, the filter is equally effective in home audio setups, such as small‑room surround sound systems, where a dedicated subwoofer channel can benefit from precise low‑frequency management. DIY enthusiasts will appreciate the straightforward wiring diagram and the ability to pair the filter with a range of compatible devices, including smartphones, tablets, laptops, and desktop computers, making it a versatile component for custom sound projects.
