Re: [Elecraft] K3 & Bose speakers
I have a set of the Bose Companion II. I really like them using them with my K3 and my computer. They have two inputs so I can listen to either or both. I have several SDRs I use with my computer to feed audio. The only time I have experienced RF getting into them is with my AMP at times. When I do I just power off the speakers and use headphones. I don't regret the purchase at all. 73's Michael, AA5SH __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 & Bose speakers
Look for a used set or new of the Mackie HR824 powered monitors. They're better than you need but they will not have Rf issues, at least they're on my desk with the K3 in-between and I've never heard anything come through them during 1500 watt transmit.

Re: [Elecraft] K3 & Bose speakers
I have a few of those "cube" speakers left over from my mad days. So, I picked up an el cheapo rar shack stereo amp and voila, Rcvr A on left channel, Rcvr B on right channel. No RF problems yet. Those who are left handed may consider reversing that !! 73, Dick, W1KSZ On 1/14/2014 4:40 PM, Tom Fitzgerald wrote: "What's the opinion on BOSE COMPANION 2 SERIES III MULTIMEDIA Speakers for use with K3 or KX3?"

Re: [Elecraft] K3 & Bose speakers
I would strongly recommend using un-amplified speakers with the K3. There is enough audio drive to handle then nicely. I was fortunate enough to find a pair of RS Optimist speakers at a thrift store, and they work great with the K3. Yes, you need a splitter to break out the left and right channels, but that is not a big chore for hams who 'build their own'. 73, Don W3FPR On 1/14/2014 6:40 PM, Tom Fitzgerald wrote: "What's the opinion on BOSE COMPANION 2 SERIES III MULTIMEDIA Speakers for use with K3 or KX3?"
