I took a Bose S1 out of Guitar Center. Tried it with the S970 and the KMA -- it could not handle the volume without reminding me that is was too small.
When I brought it back I asked him to play in the speaker room with Bluetooth from his phone. At high volume he did It fill but it was distorted.

Sad, I pictured two Bose S1 speakers one on either side of my Pa4x which is coming this week. (Honoring Stereo, ha ha Donny)

I am looking for two small great quality speakers to use with the Pa4x in my home.
