Hey @cfaniani
Ah, at least I don't have to go through all the basics?
Hmmm, nothing obvious springs to mind, just different approaches.
If the idea of a pair of self-powered PAs on poles appeals to you (as it does me for many gigs), my favorite go-to recommendation is a pair of QSC K8.2s or similar. Great AP sounds, plenty of power (you can use them for FOH for the type of gigs you do), and decent bass response. Maybe 80-85% of what the RCF TT08-a units do for a fraction of the price. In that club would be the EVs, the DXRs, etc.
If the idea of filling the room with great, crystal non-directional sound appeals to you (and it's a small or irregular room), that's where line array poles do really well. I was sharing my experiences with Kirsty a while back with the Bose L1 Model II. Even though I'm a stereo guy like you, I didn't miss it much. Just the thing for creating a warm, enveloping and engaging sound at moderate volumes. Really, really tasty ear candy.
The SSv3 still gets used, but I only can get to "OK" with the AP sounds. Unless I bring something like a QSC or RCF to cover the all-important upper ranges. And then I'm back to two pieces, but it fills the room perhaps better than a pair of self-powered PA units.
Tone: get the APs right, and all will follow.
Weight: I'm OK with multiple smaller pieces.
Footprint: yeah, cramming into a small space is a must for a lot of what I do.
Stereo: I prefer it, but willing to compromise in the face of other factors.
Given what you've said, I'd encourage you to start by finding a Bose L1 Model II. No, it's not stereo, but it would float your boat in every other dimension. Nothing else I've found really fills a room quite so well with compelling, accurate sound, including the SSv3. Until things get loud, and then it crumbles.
After that, I'd suggest that you check out a pair of QSC K8.2s (or similar) sitting on short poles. It's a directional sound, and you need a bit more space on stage, but real sonic giants for the money.
If you're concerned about stage space, I'd point you at the SS CPSv3 with the main speaker facing the floor, and something like a QSC K8.2 on top. Nice room fill, accurate sound, and less than the Bose L1 Model II above. I don't need a sub for what I do most of the time, but your situation might be different.
And, after that, we enter the world of more expensive solutions ...
