Come on its not that much...not soo much to worry about.. i would say it will be less than what our home Internet modem consume
I was merely pointing out the difference between you telling someone they consume no power at idle when that is in fact a false statement. How much power they consume wasn't the point of my comment, rather it was to truthfully answer the original question.

I don't have a wall meter available, but let's say for example these speakers pull 8W from the wall while idle. That works out to be 70.08kWh over a year if they are left on 24/7, which is roughly $9.28 a year in electricity in Vancouver. While that in itself isn't a lot, it isn't trivial, and does matter to some people.

Depends of the amplifier type, if it's a class AB, then yes the consumption would be always the same
But chances are, it's a Class-D, in which case it will draw less power when there's no audio output.

Either way, consumption should be minimal.

Actually a Class A amp would always consume about the same amount of power, while a class AB amp is more efficient. There's a good explanation here: https://www.electronics-tutorials.ws/am ... ifier.html

Essentially the analog amps are trying to avoid a little glitch of distortion that occurs when the input signal goes from zero to some value, which they do by pre-biasing with an offset signal level. But that means they are always consuming the amount of power required by the offset. Class A amps offset the full amount of the maximum signal expected, while class AB amps compromise between efficiency and the chance of distortion by using a lesser offset bias.

But I suspect the power drain of these speakers is very small when idle. The way to tell for sure would be to use a power meter. I have one, but sadly won't have these speakers to test due to the disappearance of the promo code.

Measured with a Kill-A-Watt, at the outlet - the speakers consume approximately 2.3 watts at idle.

Just to reconfirm, to use both of the speakers either VIA BT or via the Audio in jack, I need to have them hooked up to each other via speaker wire. Correct?

Good info and I don't mean to be rude but you are not grabbing these amazing speakers at the lowest they have been because the bonus 10% code that came to be a couple days after the deal came out is no longer working? The cost of less than a a Big Mac meal is stopping you?!

I ordered a second set after my first arrive, these are amazing, grab a set!!!

Yep!
The speaker you plug in has the amp and everything inside while the other is just a speaker so the wire is the power needed to run the 2nd speaker.

Thank you for the actual number. Again, they do draw power at idle.

Is it a lot? No, but it isn't zero.

You made a blatantly wrong statement to someone asking you a question, I merely corrected your facts to provide that user the truth to their question. The calculations I made were to show that even a small idle consumption is not trivial, albeit yes it is small.

I'm sorry if I insulted your ego, but take your sass and sarcasm elsewhere.

Excluding delivery fees, regulatory fees and HST - in Toronto, if left idle for an entire year, these speakers would consume approximately 20.15 kWh and cost approximately $1.79. This cost takes into account the three tiers of electricity prices that we pay here in Toronto (on-peak, mid-peak, off-peak). Hope this helps.

Just about everything nowadays is always "ON" to some degree.... TV's, AV Receivers, Android box, DVD Players, Computers, Microwaves.... The only way to turn them off completely is to unplug them.... The days of having a mechanical power switch for most products left over 20+ years ago... At least these have a switch....

Wow that's amazing- thank you! I was even able to create a device group to play two bluetooth speakers at the same time, but the delay mismatch was too long. I tried delay correction in settings but the maximum adjustment is 200ms. I think my delay is about 700ms.
