I have the Chartwell's 15Ohms and a friend of mine has Rogers 11 Ohms and another one Rogers 15 Ohms. I have in my own system compared the Rogers 11 Ohms and my Chartwells, although strictly speaking both the speakers more or less had similar sound but if one goes deep down into the nitty gritty of things than there is a difference between the two, at least to my ears.
I found Rogers to be able to handle the Rock better than Chartwells and had a bit punchier bass.
The Chartwells on the other hand were smoother at the top end and had better resolving capability when it came to the female vocals as well as slightly deeper bass. (not in volume).
Now when it comes down to personal preference one needs to consider one of the two. I personally prefer the sound of Chartwells.
By the way Chartwells are 15 Ohms
