Loudest iPads?

I'm wondering is whether or not Pros are still the only

iPads with 4 speakers. Have cheaper iPads also gotten louder? The older

Pro (2017) we own is definitely our loudest iPad, but we don't own any of the

newest non-Pro iPads, so I can't compare. I wouldn't want to buy any iPad

that wasn't at least as loud as our Pro, and I'm wondering if that

limits me to only purchasing Pros in the future. The last two pandemic

years have cut into our income, but I'd still rather save up and pay extra

for a loud iPad than waste my money on a quieter, cheaper one. Being

louder has proven that much of an advantage. I love not needing to

augment it with an external speaker.
