The switch either blocks upper bass from getting to your driver or allows it. You can hear the difference. That why they state the 8 Hz position is for a woofer (allows more upper bass through) and the 0 Hz position (does not allow upper bass through) is for a sub, but set it where it sounds best in your system. I don't fully understand the labelling of 8 Hz and 0 Hz. I am using this on a 30 watt per channel home receiver and some very small Polk speakers for the mids and upper frequencies, so I cannot evaluate it for high power applications. Right now I am using it on the left channel. But when you do this, you are missing half the bass. So I just ordered another passive sub and another crossover for the right channel, then I will be hearing ALL the bass. This is the lowest cost crossover I could find. You'd be hard pressed to roll your own at this $10.00 price point. I wish it had more specs and a schematic would be nice but you can draw one up yourself. desertcart has a Nippon sub crossover for $14.00 with more specifications, so maybe that one may better suit your needs. So Qianson, how about a data sheet and a schematic?????? This is my review; thanks for reading it. Happy Listening !!! Review: Not bad for the price - I used this on chevy dealer installed 8" kicker. It worked but lowered the volume a little. ## Features - Applications: Home Audio 5.1 bass, bass DIY，Car audio bass, bass DIY - Power: 200W (applicable to 4-inch to 8-inch subwoofer). - Speaker Impedance: 4-8 ohms. - Low Pass Speaker Bass Subwoofer Crossover Filter for 8 Ohm or 4 Ohm - 2-Way Crossover Filters Frequency Distributor ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01IZ6OBAA | | Additional Features | Bass Boost | | Antenna Location | car | | Audio Driver Size | 8 Inches | | Audio Driver Type | Dynamic Driver | | Audio Output Mode | Stereo | | Best Sellers Rank | #109 in Audio & Video Crossover Parts | | Brand | Qianson | | Built-In Media | 1 x 12V 3A Power Supply | | Compatible Devices | Smartphone, Tablet, Laptop, Desktop | | Compatible with Vehicle Type | Car | | Connectivity Protocol | wired | | Connectivity Technology | Wired | | Control Method | Touch | | Controller Type | Button | | Customer Package Type | FFP | | Customer Reviews | 3.9 out of 5 stars 112 Reviews | | Impedance | 6 Ohms | | Is Electric | No | | Is Waterproof | FALSE | | Item Dimensions D x W x H | 2.28"D x 3.15"W x 1.1"H | | MP3 player | No | | Manufacturer | Qianson | | Model Name | WEAH 90 | | Model Number | WEAH-90 | | Mounting Type | Flush Mount | | Number Of Circuits | 1 | | Number of Audio Channels | 2.0 | | Number of Items | 1 | | Number of Power Levels | 1 | | Power Source | Corded Electric | | Speaker Maximum Output Power | 200 Watts | | Speaker Size | 8 Inches | | Speaker Type | Subwoofer | | Specific Uses For Product | car | | Subwoofer Connectivity Technology | Wired | | Subwoofer Diameter | 8 Inches | | Warranty Type | Limited | | Water Resistance Level | Not Water Resistant | | Woofer Diameter | 8 Inches | ## Product Details - **Audio Output Mode:** Stereo - **Brand:** Qianson - **Connectivity Technology:** Wired - **Mounting Type:** Flush Mount - **Speaker Maximum Output Power:** 200 Watts ## Images ![200W Pure Bass Subwoofer Crossover Second-Order Crossover Frequency Distributor Divider 2 Way Speaker Audio Crossover Filter - Image 1](https://m.media-amazon.com/images/I/61tHuCn8B3L.jpg) ## Questions & Answers **Q: What are the crossover frequencies at 8ohm? and 4ohm?** A: Numerous people have asked this same question and no one knows the answer. This is a low-pass filter, that only allows bass frequencies to pass to a subwoofer speaker. Unfortunately, the manufacturer has provided any details on exactly what the crossover frequency is. The crossover frequency will be higher when connected to a 4-ohm speaker than it is when it's connected to an 8-ohm speaker. Unfortunately, neither of these frequencies specifications are included. It appears that there is also a high-pass selectable filter, that blocks frequencies below 0 Hz or below 8Hz. But there is no sound with a frequency of 0 Hz, so it's not really clear if it actually a high pass filter or not, and what speaker ohm loads these filter frequencies apply. Given the complete lack of low-pass crossover frequency information, I can't recommend anyone purchase this crossover. **Q: How to install this? It has only one input and only one output. How does it divide the frequencies to the upper range?** A: Simple installation: connect the speaker to the output and the receiver/amp to the input, make sure the wires are connected right ( - to - and + to + ) **Q: What is the crossover frequency?** A: 50-60hz is stated on the Weah 90a product page **Q: can this be used to separate standard audio signal from stereo to filter out bass (22hz) for my amp driving a sub woofer?** A: No. This is not a crossover. It is not for two-way speakers. All this does is block frequencies abovr the cutoff frequency, which another person is 50 or 60 Hz per a spec found on Ailbaba. This is not a two-channel circuit. It takes one channel of audio and blocks bass above ~60 Hz, mid-range and trebel frequencies fro being deluvered to a subwoofer driver. Someone posted a 1-star review saying they installed it between the audio source and ampkifier and it didn't work. Of course it didn't, because his is a high-level filter. Not lune level. I might buy this and test it for my application, which is to drive an older relatively small passive subwoofer from an old home theater system. This is to supplement my ADS L200C two-way speakers for a small office system. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lowest cost subwoofer crossover I could find - good quality - does what it's supposed to *by E***E on January 26, 2021* This crossover over does the job of blocking high frequencies from getting to your single subwoofer. 2 wires (+ & - ) in from your amp, & 2 wires (+ & -) out to your sub.

This is my review; thanks for reading it. Happy Listening !!! ### ⭐⭐⭐ Not bad for the price *by P***C on September 20, 2025* I used this on chevy dealer installed 8" kicker. It worked but lowered the volume a little. ### ⭐⭐⭐⭐⭐ Worked for me!!! *by T***Y on May 13, 2021* I had a cheap 8" powered subwoofer that a friend gave me when the power supply went out in it. I decided to just take the powered guts out and make it a passive subwoofer for a small amp that I have. For about $15, and a little time, it ads some nice bass to the bookshelf speakers I use with that amp. It's a small room, and I don't want to knock down the walls with booming bass. Just add some bass for the richness it brings. This accomplished that. I'm no audiophile, so I have no idea if it would be good for that type of system or not. But for what I needed it for, it exceeded my expectations and I'm happy I got it. ## Frequently Bought Together - 200W Pure Bass Subwoofer Crossover Second-Order Crossover Frequency Distributor Divider 2 Way Speaker Audio Crossover Filter - DC 12V-15V 25W~30W Subwoofer Amplifier Board Mini HiFi Class D Mono Channel Digital Audio Power Amplifier Super Bass Amp Module for PC Computer Desktop Speaker, Car Audio Speaker --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/35209031-200w-pure-bass-subwoofer-crossover-second-order-crossover-frequency-distributor](https://www.desertcart.ph/products/35209031-200w-pure-bass-subwoofer-crossover-second-order-crossover-frequency-distributor) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-27*
