Low Pass Filter RCA Connector Plug

[Jacques13]

Hi Gents

Does any one of you know where I can get these RCA Low Pass Filter plugs in or around JHB or something similar? I have heard them in action a couple of times and boy they sound good.

I want to use it on my Subwoofers with one of my Power amps.  Think you get them in 25Hz, 30Hz, 35Hz,40Hz, 45Hz, 50Hz

Here is a pic of the RCA
