About the F-MODS
Simply plug F-MODS crossovers in-line with the patch cords feeding your amplifier. They filter out unwanted frequencies, with a 12 dB per octave slope. Low-pass models let frequencies below the cut-off point through and filter out the highs. High-pass models let frequencies above the cut-off point through and filter out the lows.
What's in the box:
- 1 Pair of F-Mod crossovers (200 Hz Low Pass)

Features
Overview: The F-Mod (filter module) is an active crossover simulator, made by Harrison Laboratory, that connects in-line with your RCA patch cords. They require no power, and can be combined with other types of crossovers to change the slope and crossover frequency point. F-Mods have virtually no noise or distortion, and do not cause turn-on thumps. F-Mods can handle a maximum signal of 10 volts RMS, and have a slope of 12dB per octave.
Construction: The F-Mod is made of brass with 24 kt gold plating.
Color Codes: The manufacturer's label is silkscreened on the barrel of the device in two colors. A red label indicates a high pass filter, while black indicates a low pass filter. A colored ring near the male RCA end of the barrel indicates the frequency of the filter (-3dB). There is a frequency increase at 10K ohms (8% Low-pass, 25% High-pass) and a frequency decrease (8% Low-pass, 15% High Pass) at a 47K ohm load. A high-pass F-Mod and a low-pass F-Mod can be combined for bandpass operation.
Frequency Codes: The available F-Mods frequencies are:
Frequency | Band Color | Frequency (Low Pass) | Frequency (High Pass) | ||
---|---|---|---|---|---|
@10K | @47K | @10K | @47K | ||
50 Hz | Brown | 54 Hz | 46 Hz | 62 Hz | 43 Hz |
70 Hz | Purple | 76 Hz | 65 Hz | 87 Hz | 60 Hz |
100 Hz | No Band | 108 Hz | 92 Hz | 125 Hz | 85 Hz |
200 Hz | Blue | 216 Hz | 184 Hz | 250 Hz | 170 Hz |
500 Hz | White | 540 Hz | 460 Hz | 625 Hz | 425 Hz |

I used one of these to convert an old spare subwoofer into a mid-bass enhancement speaker for my home theater. Works great. Maybe not equal to a $500 mid-bass module especially designed for this use, but close enough and only a fraction of the cost.
