Didn't realize it had been that long since i built these
I ended up building another each of the RS100P and Tang Band.
They sit atop each other, with the RS pushed back about an inch so that the cones are phase aligned.
I use the Tang Bands for about half of my mixing, getting a lot of "the meat" balanced. I like 'em. There's not a lot of bass extension obviously, but for a lot of what I do that's not much of a problem. The grunginess did clear up.
The RS100p are good for checking what happens when the bottom end of the mix drops out. I don't use them as much as I thought I would, but they are useful.
The PA130, I use as a speaker cab option for a couple little micro amps I've built. It's more like an effect, though, as I tend to like big speakers with little amps.
I've spent the pandemic not designing and building some fostex style backloaded horn cabs to see what I think of that design with some of these options, lol. Really should get on that.
