    I have two Energy Encore bookshelf speakers in the kitchen powered off a digital amplifier. They do a fine job and have now been augmented with the Yamaha sub. The sub doesn't have a built in crossover so I just used an inline 100 low pass RCA FMOD that I had from a project years ago. What I'm running into now is that if I push the volume the Encores start to distort on the low end so I'd like to filter that out. I came across these high pass filters on PE but wondering if I couldn't build them cheaper based on their plans.

    From what I'm seeing though buying the raw components would be even more expensive.

    Thoughts?

    Thoughts on sound quality between those FMods and the cheap XO's?

    The performance I got from FMODs seemed to suggest a more modest slope than they claimed. YMMV.

    The passive crossover you posted is designed to work on the speaker level side of the amplifier, the FMOD on the line level side. SQ is likely similar. It all depends on where you wish to insert the Xover. I suggested the FMOD for ease of use, and the slopes would match if you are already using one on the sub channel.

    Sounds like a plan. A shallow slope is fine given I’m using 100hz models
