I've set the crossover to 30 hz as high pass and 80hz for low pass.
The following is directly from my older set of plans:
The Lab 12 also must be limited to 50 volts.
Groups of less than four cabs should be high-passed at 35 Hz. With four cabs or more 30 Hz is acceptable.
You can see it says
must be limited, not maybe/should/could/choose to.
These aren't like normal direct radiator cabs. They don't complain when they get near to their operating limit, they just stop working.
Similarly, the high pass must be 35Hz, not 30Hz, because you only have 2 cabs.
Both of these are directly from the man who designed the cabs. Listen to him.
Yes it matters.

The specs say these cabs are good from 60Hz up, but there isn't an SPL chart in the literature to support that statement.
The Tuba 30 will do 80Hz up to 100Hz much better than the Yammy's will do down to 80 hz or 60Hz.
I would be inclined to suggest using steeper slopes initially (24dB/octave) for the HP for the Yammies.
Either LR or Butterworth.
You do have a crossover for the tops yeah?

Please see above.
A quick look at the manual didn't really show me if the limiter was adequate for purpose, so I'll leave that to an Inuke user to answer.
The general answer though is that there a very few DSP amps out there that brick wall limit.

The differences can be subtle, but will be more pronounced when you A/B them with steeper slopes until you can start to recognise differences.
Running sound requires retraining our brains for nearly all of us by and large, it can take some time.

Thank you. The pics aren't for me. They are for anyone else who wants to see what T30's look like. Most people will look through build threads. It may not occur for them to look at a T30/crossover thread.
Having said that, your pics told me something.
They told me that your inclination is to set up aesthetically, not functionally.
To get the best out of your subs, they need to be set up for functionality.
Please read and learn this:

We call it the sub placement sticky.
The reason I recommend this is: your subs have been placed contrary to the
prime directive in the sub sticky, so they may be causing cancellations within each other.
Put the subs immediately side by side, and face them at the wall, the mouths about 8 inches from the wall.
You might be quite surprised at the difference.
Just so you know, I'm not picking on you. If someone doesn't tell you you may be doing something incorrectly, you'll never learn.
We all start somewhere...
