I've got 4 vented 18" subs with no way to have prevented them from bottoming out till now. They did provide just enough cut for me at their tuning point and I can crank my subs out just a bit more and get more out of em. I'd highly recommend these for anyone just wanting a simple plug and play option. When you factor in the price as well they can't be beat. :) Review: great product, great price. - These x-overs work as advertised. I had a serious " near sub-sonic rumble" issue. these cross overs solved the problem while preserving the musicality of my sub woofers. ## Features - 12dB/Octave slope - 24kt gold over brass construction - 10 volts maximum RMS input - One-year manufacturer warranty - Made in the U.S.A ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #70 in Audio & Video Crossover Parts | | Customer Reviews | 4.0 out of 5 stars 38 Reviews | ## Images ![FMOD Inline Crossover Pair 20 Hz High Pass RCA - Image 1](https://m.media-amazon.com/images/I/6100v-6GDpL.jpg) ![FMOD Inline Crossover Pair 20 Hz High Pass RCA - Image 2](https://m.media-amazon.com/images/I/81ES6A6Yj7L.jpg) ![FMOD Inline Crossover Pair 20 Hz High Pass RCA - Image 3](https://m.media-amazon.com/images/I/81edM6EIkcL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ These definitely worked out great for me *by B***R on December 29, 2014* These definitely worked out great for me.

I had a serious " near sub-sonic rumble" issue. these cross overs solved the problem while preserving the musicality of my sub woofers. ### ⭐⭐⭐⭐⭐ Easy to install and use *by T***E on March 6, 2014* These inline rca style filters are an easy way to cut out infrasonic noise (20hz high pass)or with more than one connected in each input terminal (mabey 20hz high pass and 50hz low pass for ex) give a sepfic range of frequency respones to your amp. These filters come in a varitey of frequencys. In my expeience these filters did not cause distortion but did give a flat sound to my subwoofers but i would still recomend them for many applications for ex. if you are getting infrasonic noise, want a narrow band of frequency response or if your amp dose not have high pass or low pass filter built in. ## Frequently Bought Together - Harrison Labs FMOD Inline Crossover Pair 20 Hz High Pass RCA - FMOD Crossover Pair 100 Hz High Pass - DteeDck RCA Splitter 1 Male 2 Female 2 Pack, RCA Y Splitter RCA Cable Audio Video Splitter Adapter Extension Cord 0.2M/0.65ft for Subwoofer 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.at/products/11431733-fmod-inline-crossover-pair-20-hz-high-pass-rca](https://www.desertcart.at/products/11431733-fmod-inline-crossover-pair-20-hz-high-pass-rca) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-09-01*
