No high pass filter on sub woofer!


Hi all,
I have a JL Audio sub that does not have a high pass filter. I am running my Harbeth P3s full range and would like to add a high pass filter. Would this HSU high pass filter do the trick?

Dear @donvito: In my first hand experiences the best way to do it that between other things improve transparency and system resolution is these:

that's what I did it in my system even that my subs comes with high pass filter :

helomech's suggestion is NOT a line-level filter. It is designed to be installed between the power amp and speaker, not the best way to do the job.
If you are open to a digital crossover these two pro pieces from DBX
are very flexible...They have an iOS app so you can make adjustments from your iPad/iPhone. You can choose different crossover slopes, it has a 8 bands of parametric EQ so you can notch out problem frequencies...https://dbxpro.com/en-US/products/driverack-venu360https://dbxpro.com/en-US/products/driverack-pa2
You can find them on e-bay...The Venu360 uses 24/96 in the a/d section for the crossover. I use the PA2 in my system and I love it...I am using for just the low pass to my two sube...but the flexibility is great.
