FMOD Inline Crossover Pair 150 Hz Low Pass RCA

Not a very sharp filter but is good enough for simple hum free filter

These don't work very well at all really.

Perfect for isolating the signal to my sub before it hits my tiny tube amp. I use these with a set of FMOD 100Hz High Pass filters to give me a really great sound. I did notice the difference before and after. These work well and are so much cheaper than a crossover. If you're looking for HIfi on a really tight budget, I highly recommend these. 95% of the performance for 10% of the cost!

I ordered these to low-pass the signal from my preamp to my sub amp (which does not have a crossover, just a big amp). My preamp has two outputs for the main. Unfortunately, because these are passive devices, they affected the sound going to my main amp and speakers. I ended up having to put another preamp (old Radio Shack mixer) before the crossover to give the isolation. In this mode, I set the mixer to mono and I only use one. In some ways this is a blessing, because I have a gain control on just the sub-woofer system now to balance out the sound (my main amp is 700+ Watts, while my sub is only 400 Watts). I'm sure in a more traditional installation, or one in which the outputs are buffered, these work fine.

Very nice for my 8” powered Sony sub. Massive improvement excellent product

Needed an easy to install out of the way cross over w/o adding a bunch of wire and more box's. This fit the bill perfectly for my mids. Good bass with no vibrations or noise.

Works good sound better 12 in sub

Remove the product from the package, plug them in to the amp and you are done. Simple and easy to install.
