Beware of generalizations about cabs. There is a huge amount of difference between the various cabs. I have two 112 cabs, a 210 cab, and a 410 cab that I currently use. I use one of the Eden EX-112 cabs for small venues and I used two of them for medium venues before I got my DNS-210 cab in December of 2019.There's only two general rules:
- in terms of loudness, 1x12 is roughly equivalent to 2x10 (and 2x12 roughly equivalent to 4x10)
- Two small cabs (1x12 or 2x10) is more modular than one big can (4x10 or 2x12) because you can bring one for small gigs, and two for big gigs.
Tone wise, it's different for each brand. Some people think that 10 inch cabs are more tight and fast and 12 inch cabs are fuller, but it's not always true, it depends on the designer's tonal goals.
My DNS-210 cab is not only much louder than one Eden 112 cab, it's louder than two of them. But it's also louder than most 410's. I use it for all my indoor venues whereas I would use the 2x112 cabs for medium-sized venues and my DNS-410 cab for large and/or outdoor venues as well as music festivals. So there's a wide discrepancy between cabs. Although I have a 2x112 set up I prefer to use the 210 and if I had done it right, I would have bought my DNS-210 cab first and then bought a second one for outdoors and music festivals because I would have in effect have a 410 set up when using both when I needed to.
