Just a thought but check the specs on your Ashdown 4x10 - namely what the frequency response is. An open E is 40hz, so speakers that don’t go down to frequencies as low as that might sound a bit lacking.
Also, SPL sensitivity of speakers is a better guide of how efficient they are than handling power.
In terms of the angled / stacked speaker cabs, I’d have to disagree in my experience. The only times I’ve done that I’ve hated the sound - too harsh and right behind my head. You might find it works, but if your cab and amp are capable then it shouldn’t be the difference between heating yourself or not.
If it’s a one-off problem it could be the room - some rooms just sound horrible.
In terms of Barefaced cabs, you might find they're your cup of tea or not. They are very light, loud and efficient. But they respond like PA speakers (full range flat response) rather than bass speakers. Excellent if you want perfect clarity of whatever sound you’re putting in.
Less good if (like me) you rely on the way the bass speakers respond as part of your overall sound.
Just my opinions obviously, and I’m sure plenty would disagree with them.
Edit - Barefaced newer 10s stuff is apparently more vintage voiced than older ones, so my opinion may be out of date as well as questionable….
