Advice on running 3 speakers from a Wiim Amp

[Rossputin]

Hello all,

I want to drive 3 (outdoor ceiling) speakers – one a stereo pair with its own nearby volume control knob (separate from volume control on the amp) and one a single speaker, also with its own volume control. Since I want the single speaker to contain the audio from both channels, it seems to me that I have two choices:

1. Run the amp in mono and connect two speakers to one channel and one speaker to another channel
2. Run the amp in stereo, connect the pair of speakers the usual way and then connecting both channels to this device to use with the single speaker: CiTR-SM Stereo to Mono Adaptor | KEF USA https://us.kef.com/products/citr-sm-stereo-to-mono-adaptor

My preference is #2 if the Wiim Amp can handle that so that the pair actually runs in stereo. (Would that really be bridging the Amp? Can the Amp do that without a problem?)

What do you think is the best solution, including any idea you have that isn’t either of those?

Thanks,

Ross

Using an in ceiling speaker that is designed to be fed both the left and right channels is another option. Polk Audio RC6s is one example. Whatever you do, you need to be careful about the impedance that the WiiM amplifier sees if you connect multiple pairs of speakers.

Connecting multiple speakers to the WiiM speaker terminals will lower the impedance that the WiiM amp sees. Go below a certain impedance and you'll create problems for the amplifier. One possible way around this are to connect your speakers in series. Do this and the amplifier will see an impedance that is the sum of the impedance of each speaker in the series and should not cause a problem for the amplifier.
