So what did you think about the sierras, and what did you decide on?
I think I made the right choice. They went well with my small-ish room.
They have good low extension and tight punchy bass. There is a good amount of bass, so much so that I could even run it without my REL sub and still be happy with the sound.
The raal ribbon is quite impressive; so much clarity and air up top.
I have no regrets going with the 2ex. The buy was sweetened by the fact I got them during the introductory/holiday discount.
