Volume Control for second set of speakers


Hi guys, anyone have a recommendation for volume control so that I could lower the volume on the “B speakers” from my amp.

I’ve got two sets of speakers in a large room and I just want to turn one set down a little to blend them better.

Something like this thing:

But maybe better? Or maybe this thing is perfect? Anyone have one?

thanks!!

Now where's Audiogon's reigning theoretical physicist when you need him? Oh well. Guess we can always use the old search engine...
because... as with everything else.... its been asked and answered:

So you can either slap a rheostat in series with the one you want to trim, or (much better) open the amp up and add them inside following the circuit diagram.

Whew, easier than I thought. Thank God, no Morphic Fields involved....

Used a Niles speaker attenuator for deck speakers for years...works beautifully with little noticeable effect on tone...plus...deck speakers for outdoor use...who cares? 
@wolf_garcia yeah my dad had one for the dining room speakers when we were growing up. Not sure what happened to it...

the speaker connection is unfamiliar to me - do you think these Lil Piggies would connect properly?
