I have used both the low and high pass filters from Harrison Labs and they work well. The attenuators work well also.
Use the -3dB low frequency response of your loudspeakers as a crossover point.

I've used inline attenuators before at home, but only low pass filters in car audio . They both worked fine.
What speakers and use are we talking about here? I'm sure the above options are better, but I wouldn't dedicate the extra cost/space for a casual setup (or vehicle).

I'd have a difficult time spending over $100 to reduce bass going to $300 speakers. What are they driven by? Any chance you can set a crossover there?

They will be driven by one of the BasX amps - e.g., A-100 or A-150. The system will also include a subwoofer(s). I'd have a difficult time spending over $100 to reduce bass going to $300 speakers. What are they driven by? Any chance you can set a crossover there? -tm |

Then, you could pick a subwoofer that has a crossover built in and includes ins/outs. The Emotiva BasX subs are one possibility that would work. There are tons of other options...
The other option I was originally thinking of was more on the pre-amp end, whatever is driving your A-100/A-150.

Thanks for replying. I'll probably use the 100Hz filters and let the subwoofer(s) do it's thing. I have used both the low and high pass filters from Harrison Labs and they work well. The attenuators work well also. Use the -3dB low frequency response of your loudspeakers as a crossover point. |

Believe it or not, subwoofers with built-in high pass filters are NOT that common. I know that SVS, Sunfire, and Golden Ear have them. If there are others, I didn't find them. The pre-amp will be the BasX PT-100. Then, you could pick a subwoofer that has a crossover built in and includes ins/outs. The Emotiva BasX subs are one possibility that would work.

Dayton and Outlaw are two more. Seems like plenty of [reputable] options to me. Or did you already buy or have something in mind?

You have a sub woofer, the woofer is on your loudspeaker. |

Let's see your measurements, I've seen those from Harrison Labs. Those devices you show are active and will introduce distortion into the chain. Harrison Labs FMODS are passive devices. Nuff said. |

Chane A1.4
Frequency Response: 50Hz-31.5kHz +/- 3dB
135mm high-excursion SplitGap mid-woofer with XBL2 motor
Improved sensitivity and linearity
Very long, linear cone excursion
Distortion reduced over 50% versus conventional drivers
Aluminum frames, damped cones, and double-ventilated motors
High thermal capacity for reliable, high output
Your Chane monitors are high performing loudspeakers. Why deny them their full potential? They are likely to sound better with a subwoofer crossed over to take advantage of their performance. Bass material can become directional at 100Hz and directional upper bass is best joining the stereo imaging of your loudspeaker pair.

The general advice for a 24dB crossover is an octave above the F3 point. You probably want the 100, but the 70 might be okay...depends on music type and how much you crank it.
Assuming same price, I'd still go external crossover vs inline.

Where the hell did you get the idea that passive crossovers were better than active? Especially an inline crossover that comes with its own set of problems. So no, Not enough said. I also doubt Harrison Labs gives a flying *bleep* about providing accurate measurements, They just want you to buy their magic quick fix. |

I don't have my own measurements because I don't have the equipment to measure, but when I had female vocals coming through my bass shakers with the 70hz low pass FMODS installed, Then I realized I needed something that actually worked.
