Installed this in a 3000 sqft hair salon with 4 6.5" pendent speakers (7.5w 70V)

It does come with an FM antenna witch was a nice surprise

Not looking to get the walls to shake just background music in a commercial setting

Very happy so far, will update if that changes

First let me say, I almost didn't buy this unit because of a very bad review from another customer. Please let me give you my opinion.
I found the ?build quality? to be quite acceptable. (remember, this is commercial audio equipment. Not ?dressed up? cosmetically.)
The functionality of the remote is sub optimal. But, I found that I really didn't need the remote to accomplish most of the tasks that I needed to do on this unit.
The overall quality of the audio is really quite good. Plenty of power for what I needed. (Music for backyard patio, deck, fire pit area etc.)
The FM tuner built into this unit is really quite good and stable. It does take quite a bit of time to move from one station to another.
The Bluetooth section works well, pairs quickly, and sounds good, but, it has very limited range. My iPhone needs to be within about 10 feet or so of the unit.
I'm not using any of the paging functions of this unit so I can't comment on those features.
Overall, I am very pleased.

Build quality is terrible. Sounds decent, but see problems in the future. Also, MUST use the poorly designed remote to do most functions.
