Like for 4" bookshelf speakers? Did it color the sound?** A: I use them on a pair of 5" active studio monitors. The sound is not colored, they removed those low frequencies that caused the extensive woofer movement and "bottoming out" of the woofers. I did add a subwoofer to the set to make up for the lost low end below 100 hertz. Actually I am impressed by their performance. Don't forget the connectors you will need to use them. **Q: Are these good to get rid of engine noise in my door speakers? Thanks** A: Antonio assuming you're using these on the signal inputs of a car power amp, they will remove all low frequency sounds below 100 hz. That would remove most of the low bass notes from your music. Engine noise is more likely to be an issue of cable shielding and/or grounding of devices. **Q: When plugging them in, are these directional?** A: I didn’t see any indication of direction on them. The direction I’m using is source audio plugged into the female side, then make side plugged into amp. I haven’t tried the other direction. **Q: Cheap active sub no crossover, running off line out of power amp. Do I need high or low pass 100hz to cut off all signal above 100hz?** A: Running it off a power amp - yes you do, otherwise you'll get the sub trying to reproduce the whole range; 100hz low pass (black writing filter will work (FMOD Crossover Pair 100 Hz Low Pass ). ## Customer Reviews ### ⭐⭐⭐⭐⭐ 簡単です *by on Reviewed in Japan 30 August 2026* 期待通りの性能です。 ### ⭐⭐⭐⭐⭐ Works well, not too expensive *by on Reviewed in the United States 10 August 2025* Works as expected, sounds good, no notes. Not a lot of options for this item but this brand seems pretty good for the price. ### ⭐⭐⭐⭐⭐ Super convenient crossover. Great build quality. Good sound quality. *by on Reviewed in the United States 25 May 2024* I like this company and their products. I have both high pass and low pass versions of this, in both 100Hz and 70Hz for subwoofer bi-amping/by-passing. Good quality product, good fit with my RCA cables and amp connectors. Small and unobtrusive. I did not do any scientific measurements on these items. From experience I know that a good quality crossover can easily cost several hundreds of dollars just in components, so... I am not sure how they pack coils, resistors and capacitors in these small devices, but they do seem to work. It sounds pretty good, and I have a highly resolving hifi system. ## Frequently Bought Together - FMOD Crossover Pair 100 Hz High Pass - FMOD Crossover Pair 70 Hz Low 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.be/products/510929443-harrison-labs-fmod-inline-satellite-electronic-crossover-pr-100-hz](https://www.desertcart.be/products/510929443-harrison-labs-fmod-inline-satellite-electronic-crossover-pr-100-hz) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-06*
