My experience is similar to Blkadr when it comes to the midrange and highs. I have the 12L2. The mids are a bit recessed, at least compared to my Tannoy DC6. But even before I had the Tannoy to compare them to, I suspected it. The highs are nice and clean, but do not sparkle like the highs on the DC6. This is all subjective stuff though. Some here may enjoy the more forgiving highs and the somewhat recessed mids.
The bass is huge on the 12L2. It can sometimes overwhelm. This was not the case on my old speaker stands, but it is on my new stands. So this will clearly vary depending on what you put the speaker on. The DC6 is a smaller speaker and seems to be a more natural fit in my room. So given the OP has a small room, I could easily see the 11L being a more ideal fit. But if you put the 12L2 on the right stand, it will probably be fine. Like with many things I'm finding in this hobby, you can tackle a problem a few different ways and yield good results.
