In a word, pleased. My powered subwoofer has a crosser knob but it never seemed precise enough or maybe I didn't like the slope of the crossover. As soon as I added the FMOD Crossover Pair 100 Hz Low Pass to my sub all low frequencies content cleaned up and all the flubbiness disappeared. Giving my subwoofer the right crossover to match my speakers if a big help too. Possibly a slight dip of 2-3 dB in volume to the sub (could just be the slopes effect), but just adjust your sub level and you good to go. Pro tip: if you want 100 Hz crossover but with an even steeper slope, plug two 50 Hz FMOD's together in series and you'll get a steeper crossover slope at the same crossover frequency.

My husband bought these to use on the amp in his car. They function like they should and work good. He used it in his Volt and said they pick up a little electrical noise but it's not bad. If used in a regular gas car they probably wouldn't do that.

I'm using these for an outdoor buried subwoofer. It's much more economical than a DSP amp and it has greatly cleaned up the sound with my setup. Extremely happy and exactly what I was hoping for.

This unit Worked perfectly!I used in place of a Rackmount 2-way crossover.100hz 12db low pass hooked to a Crown Power Tech 2 with a JBL JRX 100 18 Sub. The Top was a powered JBL EON 615.I couldn't have been happier with the sound

These worked just fine and blocked that treble out before sending the audio to my subwoofer amp.

I bought these to pre-crossover an input to an amplifier that is driving a subwoofer. Took out all but the bass for a much cleaner sound.
