I'd be wary of bluetooth for audio. The latency involved can be spectacularly bad. 40ms plus bad.

In your mixerless setup, to use the monitor wedge as a monitor I'd just put an eq/feedback destroyer in the line between the Alto and the wedge.

Back in the day, they had not yet come out with the smaller compact self powered speakers you could throw in the trunk of a car.  So we had to lug around big, heavy cabinets and huge bass bins and  impressive looking horns sitting on top of a tri-amped speaker stack that could shatter glass and cause seismic events. It took a truck to get the gear to the gig, but that was the style and that's how we rolled back then.

I see bands now who have 2 small speakers and a sub and sound good.... so times change.

Yes, PA design has improved massively over the last 30 years. I remember the "old style" PAs built of stacks of black-painted 18-ply cabs, huge bass horns, hf drivers with lenses stacked on top of the mid range bins, the whole thing six or more feet high. They may have been huge, ridiculously heavy and have poor sound performance compared to the modern setups, but didn't they look impressive compared to the now ubiquitous cloth-fronted plastic boxes?

Nice idea (duh on my part) for a feedback buster in the line - now I will have to go find one... BTW this Alto Pro-Trouper is great for a soloist in a small / medium venue... Looks nice, solid and good sounding...Price was right too

Interesting to hear of someone using one of the Bose arrays. I've considered them in the past, but the price and not being certain of their sound and feedback resistance has put me off so far. The Bose 802s and similar have always struck me as a bit like a Yamaha NS10, all mids, unless the expensive Bose eqing speaker controller is used with them (and most users seem not to buy the controller and never notice their sound is almost entirely mids. Not too bad if used just for vocals, but as a substitute for full range or even 12"+horn powered cabs they've never struck me as particularly good. Though their lack of weight is a stong point.

Out of interest, do you know if the array you've heard was using an eq to correct poor treble and bass?

I have a similarly low opinion of Bose stuff, and in fact tried to talk my friend out of buying it at the time. But he was tired of schlepping heavy speakers (JBLs), liked the portability factor and ignored my advice.
 
The first time I did a gig with him using the new L-1, I was quite surprised at how well it performed. Adequate volume for a 200-seat room, excellent clarity on vocals, and zero feedback even though it was set up between and behind us. There is no EQ on them. Of course there is EQ on the mixer channels, but if we use it at all it's to roll some bottom off to offset our microphones' proximity effect, never to mitigate feedback.
 
I can't argue against the practicality of the Bose. It breaks down into components that even I can carry without fear of back injury. No need for speaker stands, so that's two more items that can be left at home. No need for monitors. No need for the mini-van anymore, either. If not for the bulky Anvil case that holds the mixer, effects, wireless receiver, tuner, etc., his whole rig would fit into the trunk of a passenger car.
 
I have just one complaint, and that is its weakness at the frequency extremes. The low end could be beefed up with the addition of a larger and/or second woofer. The amp will handle two subs, and Bose makes two sizes of them. The lack of high end, though, seems baked in. Given that they are 3" speakers you'd expect them to be brighter. Maybe they do have a hard-wired LPF built in, I don't know.
 
In any case, I didn't like the sound of keyboards through it and continue to use a pair of 12" keyboard amps for myself. He may have a supremely portable rig, but I'm still using a hand truck for mine.
