Nice cabs, I had the 210/115 for a short while but moved the 115 on to get another 210 - made the sound more punchy. They sound very ABM like, maybe not quite so scooped and low-end biased. On regular sized stages/pub gigs I didn’t notice much difference at all between them and my ABM cabs. On bigger stages it does become apparent, the weight of sound of the ABMs comes across better.
I had Ashdown put in some Eminence cones in my RM210s to increase power handling, I then sold them, and then in an about turn bought them back a couple of months ago. Great cabs imo.
