Product Details

Harrison Labs FMOD Inline Crossover Pair 30 Hz High Pass RCA
What is an FMOD? The FMOD is an active crossover simulator. It is better than a much more expensive electronic crossover that requires power to operate. FMODs are packaged in pairs and can be combined with other FMODs to obtain bandpass ranges or with other types of crossovers to change the slope and crossover frequency point. FMODs feature a 12 dB per octave crossover slope and are compatible with all RCA type input amps...simply place the FMOD in-line with the patch cable running between the source (head unit) and the amplifier. 24 kt gold over brass construction, 10 volts maximum RMS input. One-year manfacturer warranty. Made in the U.S.A.

Harrison Labs FMOD Inline Crossover Pair 30 Hz High Pass RCA
Harrison Labs FMOD Inline Crossover Pair 30 Hz High Pass RCA is rated 4.6 out of 5 by 5.
Rated 5 out of 5 by from Great productExcellent way to add a subsonic filter to an amp that doesn't have one. I contacted Kicker who recommends a 25hz at 24 db per octave and they said this one at 30hz 12 db per octave would be fine... works very well.

Rated 5 out of 5 by from NecessaryIf you are using an amp without sub protection circuitry you need this. It stopped my sub from bottoming out and extreme lows.

Rated 4 out of 5 by from Good product, I recommend itThis product did take 95% off the signals below 30 Hz. It doesn t work on turntables without pre-amp like mine, I did find out by talking to costumer support "Skip", which helped me a lot with the issue I had. I have another receiver and used it as a pre-amp and then connected the FMOD in the tape output and it worked great.I recommended this product as it almost got rid of all of the rumble I was experiencing with my turntable when playing.

Rated 5 out of 5 by from for Price to performance, can't be beatThis works great as a cheap alternative to a crossover. Using as a Subsonic Filter on my sub outs. Only gripe, wish they came in -18 or -24 dB. you can have 2 with an attenuator but your getting a little bit expensive that way. Great product, easy to throw in, would buy again.

Rated 4 out of 5 by from Easy to useVery easy to use in line-out, line-in applications. Harder to use as a crossover between two speakers (not sure of the ultimate "quality" of the innards).

Harrison Labs FMOD Inline Crossover Pair 30 Hz High Pass RCA

Is the HL FMOD 3500Hz HP crossover a good choice for JBL ST 400 TRIO ? The input will be only apx 60 watts.

Asked by: tweet 60
The manufacturer recommends a 5k high pass at 12 db on that driver so 3500 is a little risky.

Hello I have a Wharfedale Subwoofer with 10" Driver, Amplifier 150W RMS, Frequency Response 35Hz to 110Hz. The problem is that frequencies under 35Hz cause it to rumble and have allot of port chuffing. What high pass filter should I get the 30Hz or 20Hz?

Asked by: JohnNorman
I would recommend the 30 Hz filter for this application.

What is the Qx of this filter for input into Bass Box Pro?

Asked by: Imastud71
According to the engineers at Harrison Labs, the FMODs don't have an internal resonance (or Q). Notice that the Qx in Bass Box is referring to an active (electronic) filter. The FMODs are a passive device. Speaking in terms of parametric EQ, I believe a 12dB slope is approximately a 0.7 Q, but don't quote me for gospel on that. Also note that if you do not input any data, and simply allow the software to suggest an optimum internal volume for your enclosure, it will also estimate the proper Fx and Qx automatically.
