Over the years, I’ve had open baffles with multiple 8s, multiple 10s, and multiple 12s.
None can defy the laws of physics.
If you like loud and deep, 8s get you low enough to cross to subs at 100hz or so, 10s at 70hz or so and 12s at 40hz or so.
Unless you can fit quad 12s or more, at some stage you are going to need monopole subs.
Your choice is when.
Assuming your Wedgies are good to 200hz as mentioned, your current bass stands give you an extra 100hz. That’s not a lot given the cost and complexity.
I like open baffle bass. But I like loud and deep bass more.
That’s why, these days, I go servo monopole below whete my Neo10s can get me.
