I've been very happy with some ComTek(sp?) powered speakers from DX Engineering.

With respect, Danny, my RFI was definitely coming from the switch mode power supplied by Bose and completely disappeared when I replaced it with a clean supply.

Obviously your mileage does vary.

No disrespect sustained Winston. But my station is entirely 12VDC powered (except the linear amplifier) so that may have been the case with the pair you have. But that was not my experience. I was surprised , disappointed, and frustrated as well; to find they still emitted RFI even while being powered by pure DC from a battery. As I mentioned earlier, I tried with two different sets from two different vendors. I didn't imagine it.

Very interesting Danny. I also run my entire remote station on solar charged batteries and only use my inverter for the 2K-FA, however the Bose Speakers are at my home where I do all my operating from.

Just out of interest, and as an experiment, I will take the speakers up to the remote site early in the new year and see what happens when they are co-located with the 6700.

To be fair to Bose, the RFI is low level and may or may not cause a problem for any particular station depending on distance to antennas. I simply didn't want anything adding to the noise floor.

Altec Lansing powered speakers work fairly well for me but they may have a little susceptibility to rf however, among the ways I have mitigated it is to run the main speaker input to the flex and if you want to run the Computer off the same speakers then use a separate line to the speakers if possible. Many times it takes some ferrites on power and speaker runs to help the rf issues irregardless of the speakers you choose. I can run legal limit without any major speaker issues.

I have a pair of JBL Control 2P.  Very high quality and loaded with professsional audio features. I have never had any RF interference and I feed the audio to the speakers from a Behringer mixer.  That allows me to send computer, Yaesu FT991 2 scanners and of course my Flex 6300 audio.

For 52 years I have found headphones the way to go.

I am also using Bose Companion 2 series. I am very happy with sound quality on CW and SSB.
Warm and clear yet a full sound easy to understand. Found them actually on eBay in mint condition with an unbeatable price. I have tested also some other 2.1 Speakers from Dell and Creative but I have to say Bose Companion beats them all. I have to add to that they are directly connected to my Flex 6500 and they sound better compared to when they are connected to the PC. Not sure what sound chip is in the radio but sound is really amazing. 73 DM1TX Val

I recently purchased the Bose Companion 2 Series 3 speakers to use with my 6400M. Bought them at Best Buy. I am very happy with these speakers and not a hint of RF.

Yeap Mike. I said the same. I use them with original supply. Sure I had a ferrite here and there but as I said they are directly plugged into the back of my 6500 and I am really happy with them. 73

I would love to recommend the Bose Companion speakers. They have the perfect form-factor and sound bodacious. However, as noted by K5CG, they induce spurious emissions on several bands. Relatively low-level (mostly) but annoying. My first thought was the power-supply but the same symptoms occurred when powered directly from a 12-volt lab supply. The DSP shielding is simply inadequate. Fine for pure audio applications, but problematic at HF.

There's a good chance that the  Bose Companion 2 Series speakers use class D audio amplifiers. If so, no matter whether you use battery power or not they may still be a source of RFI.
