It's covering a even larger span in the df-8 model and i asked them about this and they stated that there woulsn't be a glap becuase of the dome tweeter, however i am not convinced of that. There is many speakers with good value like ztz 99.36, elac also makes good value speakers that are made in germany.

I am considering a pair of elac 249 but first i will do some listening with studio quality music. I think i will go for prepro+amp. I am skeptical against audyssey pro atm but i will read more about it and see if it's justified. Model 978 might work as a temporaty sulotion.
