Paradigm vs Dali vs PMC

Well then the FB1+ will probably knock your socks off withits bass response.

For pure accuracy and ease of placement the Paradigm are probably the best choice - they have an extremely even response. You can see they have a waveguide on the tweeter so they match the limited dispersion of the all too large midrange driver to get as even response as possible. The more rigid drivers in the Pardigm will give a bit of out of band ringing or sheen to the music - you need to decide if you can live with that.

I won't commment on the Dali - I am not a fan of ribbon tweeters - they often tend to have distortion low down in their frequency range - although extremely expensive ribbons in teh best speakers can be exceptionally good (but why pay $200 for a ribbon tweeter that a $29 soft dome vifa can compete with in a mid level design)

With regard to Dali, they have dual tweeter - soft dome for the lower high's and ribbon for the range above that, SO perhaps that solves the distortion issue.

It most certainly would - it might explain why they went with that design approach.

not a big gripe I suppose

If you look at the plot the woofer breakup is only 10 db down...this should have been eq'd out more aggressively. I would be very wary of that...it looks as if it will be audible. I haven't heard them so I can't say for sure but you really should audition them for yourself.

Midrange is critical in a speaker.
