Interference from TP-Link Powerline Adapters

Painkiller

Can anyone tell me if a device exists that my Logitech Z-5500 Speakers could plug into that would cut out the interference/signal from the powerline adapters?

When the powerline adapters are switched on, the subwoofer constantly rumbles and emits a random popping sound.

Make sure you don't have the subwoofer plugged into the same socket as a powerline adapter, If they aren't in adjacent sockets then you need to look for a "mains conditioner" but decent ones don't come cheap. If they do a mains extension for the subwoofer or plug the powerline adaptorin further away and use a longer ethernet patch lead.

A powerline adapter plugged in upstairs causes interference on the speaker system in the living room downstairs so increasing the distance between the adapter and the speaker system isn't feasible.

Would the Tacima CS929 6 Way UK Mains Conditioner and RFI Filter Surge product be sufficient or is it just an over-hyped surge protector? It's the only affordable mains conditioner I've come across.

try a surge protected computer extension lead some have mains conditioners built in

The adapter that connects to the router and the adapter that connects to the switch downstairs are both on surge protected extension leads so those particular extension leads (made by Stanley & Masterplug) don't inhibit the powerline signal.

I wonder if running the power leads of the sound components through ferrite rings might kill the interference?

My TP Link AV500 adaptors caused a mild 39 Hz rumble in my Z-5500 sub when in use, turned out to be a couple of leaky capacitors in the power supply which I replaced for the grand total of £3.74 inc VAT.

Ferrites are for blocking common mode currents and won't help in blocking the interference signal from homeplugs. Surge protectors are just spark gaps put across the circuit and won't do anything to help this.

I've no idea if the Tacima unit would work but they are sold on Amazon who are excellent for returns.

TBH though QuietSpark has probably pointed to the issue - a faulty subwoofer. How you go about getting that sorted out though I don't know.
