I've done a couple of open mikes using the Bose system, not sure which one , I was told the system retails for around $2000 and it belongs to Apple Music , a local music store. Anyway, the sound was excellent 3 out of 4 times, the last time they had a fan running to cool the club and the wind from the fan was causing noise and canceling out the sound, but every other time I could hear my guitar and vocal pretty clear and the sound was getting out very nicely. Just a guitar /vocal set up with 2 mikes but I play a lot of damped bass strings and they were coming through clearly.
