Do the Bose Companion 2 Series iii speakers enter a sleep or standby mode if the Flex is powered down, or should then be turned of manually? If plugged into the radio directly, or the Maestro.

My same speakers are always on 24/7/365. I don't think they go to sleep or power down.
They are easily turned off and on.

I have been using these for years and they don't power down.. but I wouldn't exactly call them power hogs either.   but to turn em off you just need to spin the knob around to a click.  I just leave mine on.

Are you guys getting RF in your speakers and an AC hum? I think I might have a poor input cable coming from my Flex.

No amp and I have not tried QRP yet on SSB, and now come to think of it I can't remember if it was on the hex or the 6BTV that gave me issues. When I get home I'll test and even on the dummy load.

Sure sounds like a choke is needed.  maybe more than one.

If you are connecting the speakers to both the rig and your computer at the same time, you may be experiencing ground loop problems, as I did. When transmitting, there developed a ground potential difference between the computer, rig, and speakers, this small voltage difference on the ground return was large enough at audio input levels to be amplified by the speaker amplifiers and was loud enough to be annoying. It sounded just like I had RF in the system.

The solution was to add a ground loop isolator on the computer side. They are available on Amazon for under $10 US.

Here is what I use: the Pyle PLGI35T. ($8.70)

There are other newer designs that are smaller. For example, AUKEY ground loop isolator for car stereo and home stereo systems. ($8.99).

Add a couple Mix-31 ferrite for additional isolation if needed.

Nope straight from the Flex to speakers but it does cross a few other wires in the back of shelf under the desk. I'll mess with tonight after I get the pool up and running, it's getting hot out here in the desert.

I had some ground loop hum on my Audio due to the use of an audio switch in line.  fixed it with in line audio isolation transformers.  They are available from Amazon in many forms.  Mine have 3.5 mm audio jacks m/f  here is a reference to them.https://www.amazon.com/gp/product/B019393MV2/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

I also use them from my computers to the audio switch, also helps with RF....

I have had the bose speakers until they broke. Not impressed with them. They were pricey ($275), produced noise in the band from the power supply and have to be on all the time with no auto sleep. They do sound ok. They broke, they are glued together so I cannot service them without breaking them and I am out of warranty.
After reading some positive reviews I decided to try the Yamaha NX-50 as a replacement for the underwhelming Bose.

I am very happy camper. Better sound, cheaper ($99), properly shielded (no rf issues), two inputs (like the bose) so i use them for the Flex and the computer audio, auto sleep mode and several color combinations to choose from. If you are in the market for something similar to the bose I would check out the yamaha NX-50.

You may want to try the Bose Companion 20 speaker system. These do cost a little bit more, but they have zero issues with RFI, etc., and they sound oh, sooooo good with the Flex 6700!
