[Elecraft] OT: Speaker Wire Recommendations?

[donovanf at starpower.net]

Clay, 


You'll get more meaningful feedback if you move this RFI discussion 
to the RFI reflector. The Elecraft reflector is the wrong place for it.

If you're using passive speakers as you implied in your email, a ferrite core 
at each speaker connection to your amplifier should do the trick. 
Suggest you disconnect all five speakers and reconnect them and 
work on them one at a time 


This is an excellent resource:

Subject: [Elecraft] OT: Speaker Wire Recommendations? 

OK... so I am knee deep in assembling and installing a subRX, et al., 
but got reminded by the XYL that I STILL have not addressed the signal 
bleed into the audio system via the long runs of parallel conductor 
speaker wires in the HT setup. 
In order to maintain a high "SAF" (Spouse Acceptance Factor), I need to 
deal with this issue WHILE I am in the attic re-configuring the network 
and routing various shack related wiring. 

I cannot imagine a stellar group of operators as are gathered here have 
not had to deal with this before. <grin> I am hoping that replacing 
the speaker wire with either simple twisted pair (or shielded, twisted 
pair, w/shield properly terminated) will mitigate the hits the HT system 
is taking. 

*Q: Do any of y'all have recommendations for a particular wire stock 
for use in this application?* Small system... only about 50W per 
channel on the 5 main speakers, so they don't have to be monster-sized 
conductors. I considered using CAT-5(+) wire and bonding all 4 pair to 
a single loop, but I don't think a single run would be enough copper 
(?), and I don't want to make multiple runs per driver. 

*Any ideas?* 

73,
