Great reply jazzmammal.

Initially I was convinced to start with a single qsc 10.2
I could add another in the future if need be.
Its light enough yet powerful.

Then i got sidetracked with line arrays.
The Bose L1 model 2 with a B2 or 2 B1 subs and a ToneMatch mixer is clearly a kick [*****] setup.
It is 2 trips to the car to move it all
The b2 sub weighs as much as a Mesa Boogie Mark 3 (45lbs)
Note:I just checked and the L1Model2 with a B1 bass and a ToneMatch 4 mixer is about $2.5k.
A special is on till end of July. That saves just shy of $500.
Its like the internet knows what I'm thinking. Likely it does.

Perhaps I should just pull the trigger on the Bose Model 1. I can handle the expense.

Your final point hits home squarely. I do wonder about the quality of my backing tracks.
Most of them I make myself with BIAB and little else.
I would love to get some feedback/coaching on my work to make them as good as possible.

Any idea on a resources to improve creation/editing backing tracks?

Again, thanks for your time.
