Hams do not "broadcast", they communicate. Radio and TV stations broadcast.
That said, what are you using for an antenna. Most RFI in the house problems are cause by poor antenna installations (end fed wires with no counterpoise, for example), antennas inside the house and outside antennas too close to the house.
The fact that most computer speakers are really trash, and very succeptable to interference, just compounds the problem.
All the filters and ferrite cores on the wires won't do a whole lot if the primary problem is RF in the house from a poor antenna installation.
