Actually they are high-pass RC filters, easy to DIY on your own. Simply a capacitor and resistor in series. The idea is to high-pass the RF from the speaker cables through the resistor, where it dissipates as heat. There are quite a few threads on the Audio Asylum Tweaks forum with different formulas for making your own. I made mine using cascaded silver mica caps and Texas Components TX2575 resistors, all wrapped in TI Shield and potted in small ABS boxes. I matched the resistor value to the characteristic impedance of my speaker cables for maximum RF transfer. I use one on each end of the speaker cables, between + and - . I do hear a difference in upper range clarity when they are in the circuit.

I just recieved some sets of these for my Bi wire speakers.
Not sure if these take time to break in.
I was told they sound great right away, others have said they take a few weeks.
Right now I am not sure if they are doing anything. I also have the Ground Controls on the speakers.
I was wondering if anyone else has these and perhaps could give an opinion of these compared to the Walkers.
