FMOD Crossover Pair 70 Hz Low Pass

Connected these to the output of an AirPort Express for airplay from my TV to my subwoofer. Works great to drop out the high frequencies. Now I have my subwoofer working in conjunction with my Apple TV and my HomePods.

This works absolutely perfect. I turned the xover on my amp all the way up and am using this as my xover and it's amazing. I didn't realize this also gives a db gain. I had to turn the bass down so I could drive. Everyone keeps saying how much better it sounds now. Super easy to install too

These are good in the sense that they are extremely easy to setup, intuitive, and require zero configuration. But honestly, they just don't work very well... I was using these with my subwoofers, trying to filter out everything other than the bass. But even with just my subs active, it was amazing how much higher-frequency content was still getting through. You could still clearly hear all of the vocals, etc. All through the subs. I finally went with an actual DSP and the difference was night and day. Literally nothing but bass comes out of the subs now. But I understand that not everyone is going to want to deal with something like a DSP, and these adapters are still a good option for those willing to accept a "bare minimum" solution.

I bi-amp my system and run the full range open baffle speakers straight off a SET amp with nothing in the signal path to mar the sound. Can't do the same with bass woofers as they require a low pass filter and that's where the F-mods come in handy and provide a simple solution. Previous to my purchase of the F-mods I used an electronic crossover which worked but was expensive and unnecessarily complex. I use a class D amp to drive my bass woofers and the F-mods are installed up stream and on the inputs of that amp meaning they change the frequency before the signal is amplified. That means you don't burn off power like you would with a conventional passive crossover which changes the frequency after its amplified.

They work good, they removed around 80% of the higher frequencies which was nice. I can't really hear them anymore. I don't have them stacked on a 24 DB slope, I'm using just one each, on each channel, and they still work fine.Only complaint is that they took forever to ship, from both PartsExpress and the current seller. So plan ahead.

Enabled me to use a Def Tech Supercube without a low pass filter with my Harmon Kardon stereo receiver that has subs out jacks but no bass management. Without it, the poor little Supercube sounded like an awful speaker receiving a full frequency signal. With the filter in place it became the below 70Hz little monster it was intended to be

The media could not be loaded. I bought the 70hz low pass filter and it doesn’t cut my sub off at 70hz, try more like 200hz. I went into fl studio and set a manual low pass filter to test where it actually cuts the sub of, and it’s more or less around 215hz. It’s installed correctly, it just doesn’t work properly…

I had to much bass coming from vocals in talk radio. I thought, could the shop not have put a crossover on the sub?Couldn’t find a crossover in my head unit and got these and it tightened up the bass in music and helped tremendously for talk radio.
