"flatpacks?"
speaker hardware dot com does flat packs.
''How loud is it?''
"depends what you load it with"
Well; no. There aren't really choices that effect overall output db, IME.
Yeah you can run an alpha 6 or a faital 6 or an NDSound 6, but all that does is change midrange character.
In my opinion/experience.
"it replaces a 410"
BS!!!
Look, it's a great 112 cab, but it's a great 112 cab, and that's what it is.
I have one, I use it, I love it, and I'm not happy with it on it's own except at rehearsal.
You'll get a lot of other opinions on that; there's mine.
If you want it to be "410 equivilant or better" then, plan on a 12 sub with it.
I have and use that combination, it SLAYS!.
I use a 15/6/1 most often out of all my stuff. It's a great standalone cab. The 12/6/1 isn't a great standalone cab; for me.
The 12/6/1+12 sub out-decibels the 15/6/1, to my ears. Maybe that's because it's a lot taller and closer to my ears; maybe not tho.
And, 12/6/1 over 15/6/1 is just ridiculous.
