PMC OB1i feedback

Have you ever compared them to the new twenty 24 ?

Yes. The 24s are fantastic speakers but they are slightly more forward sounding. I prefer the ob1i to the 24 especially for rock.

I'm ultimately trying to decide between the FB1i and the OB1i and if it is worth the $2K difference.

I know the OB1i is better....but is it "that" much better ?

I really enjoy my FB1i Signature speakers, but you have to move up to at least the OB1 to get the PMC dome midrange, which is part of pmc's "claim to fame" - but then you have a 3-way crossover. Without the more complex crossover, the FB1i is more sensitive, so all things being equal, you might have to spend more to power ob1's sufficiently for your purposes.
