Review: These definitely worked out great for me - These definitely worked out great for me. 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 - Crossover Slope: 12 dB per Octave - Input Amp Compatibility: RCA Type - Construction: 24 Karat Gold Over Brass - Maximum RMS Input: 10 Volts - Origin: Manufactured in the U.S.A ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0006N41BU | | Best Sellers Rank | #87 in Audio & Video Crossover Parts | | Customer Reviews | 3.9 3.9 out of 5 stars (35) | | Date First Available | October 31, 2012 | | Department | unisex, all ages | | Is Discontinued By Manufacturer | No | | Item Weight | 1.44 ounces | | Manufacturer | Harrison Labs | | Package Dimensions | 4.21 x 2.8 x 0.51 inches | ## Images ![Harrison Labs FMOD Inline Crossover Pair 20 Hz High Pass RCA - Image 1](https://m.media-amazon.com/images/I/6100v-6GDpL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ These definitely worked out great for me *by B***R on December 29, 2014* These definitely worked out great for me.

No record is perfect and wanted to prevent speaker damage for songs at the outer edge. While these do tame down subsonics they do take away from the clarity of my system. They can be a cheap bandaid but long terms something else is needed. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/11431733-harrison-labs-fmod-inline-crossover-pair-20-hz-high-pass](https://www.desertcart.fr/products/11431733-harrison-labs-fmod-inline-crossover-pair-20-hz-high-pass) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-22*
