Yesterday I used one bose s1pro on the floor tilted straight back for a 30 person assisted living group on battery power.
everybody loved the sound. they sound great with my pa1000. I could have just used the korg because the speakers are super strong but I didn't want to push it too hard so the s1pro just helped a little. Just perfect for these types of jobs. It also gives me plenty of extra power if I need it.
