Been thinking about starting a build soon but I’ve been doing more last minute research on a few things.
My initial plan was to build a three way system, using an OmniTop 15 for the mids and an OmniTop 12 for the highs.
The lows would be handled by T60s.
Just curious if this is something that’s doable or if I’d just be better off using just one of the OTops for everything above 60hz.
Or would I be better off using something like a DR 280?
Three way system?

Re: Three way system?
The OTop 12 and 15 are both 2 way mains. The 15 goes a bit lower. Have you looked at their SPL charts?

With the right DSP settings, would it make a difference?
If not, I’d love to be able to just have one cab take on everything after the sub frequencies.

Re: Three way system?
Either the OTop 12 or 15 will take on everything, all that differs is where they cross to the subs. I've yet to see a review that says the 12s don't go low enough. As for crossing at 60Hz that's much lower than necessary even for home theater, let alone pro-sound.

Welcome back Jay.
Have you done any research that Grant had suggested back 18 months ago? I am asking because you were looking at the T60.
Anyway, I think an OTop12 will be enough, especially if you cross around 100hz. Here is a chart with each cab having melded piezos.
