## Description

Harrison Labs' FMOD Inline Crossover Pair, a 20 Hz High Pass RCA model, serves as an active crossover simulator, outperforming pricier electronic crossovers that demand power. Bundled in pairs, FMODs can be merged with others to achieve diverse bandpass ranges or combined with different crossover types to adjust slope and frequency point. Boasting a 12 dB per octave crossover slope, they're compatible with all RCA input amps. Just insert the FMOD inline between the source and amplifier using a patch cable.

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.

### ⭐⭐⭐ HMMMMM - kinda work
*by T***S on January 16, 2023*

I have the classic problem with rumble when starting my records. 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.
