Focal Utopia monitors: Diablo vs. Micro Be

I now understand your description of ES, yes Diablo have some Bloom in lower mids and tranparent extended hights and its realy one of the fastest speakers out here. However I completely disagre about midrange presence- Diablo have better than electrostatic IMHO. its pin point unlike ES.

Your Accuphase integrated is 60w with Micro Be not 30W. I would cosnider 80-100w and 100-130w optimum(bigger wont hurt either) to reach both speakers maximum spl abilities..
You shouldnt worry about protection of Diablo tweeter BTW, as it have good protective grill(I STRONGLY recomend pick up grile in place when not listening if you have kids, pets or wifer who like to clean around..)
I looked at Your system, its realy nice and simple (uncomplicated) good luck.

Elviukai, according to the Focal documentation the nominal impedance of both Diablo and Micro Be speakers is 8 ohms. As I have mentioned twice in my post my Accuphase outputs 30 watts into 8 ohms loads. The E-550 amp will output 60 watts into 4 ohms loads, however, according to the Focal documentation the lowest impedance of Micro Be is 5 ohms. Thus, unless the information on the Focal manual and site is wrong my amp will not output 60 watts when driving the Micro Be speakers. Into 5 ohms loads the Accuphase E-550 amp will output 48 watts.

Hmm.. my expierence says that specifications on websites is for.. comaparision with other manufacturers, nothing more. and its fine for that purpose (assuming all says the same "true")

OK I checked, the lowest Micro impedanse is 4.2ohms , while rdc is 3.7ohms its definately 4 ohm speaker and your accuphase will deliver more current. Diablo have very similar results, thought its electrical pahse shift and impedance changes is much smoother than Micro. both speakers are easy to drive (this is not Maestro with 3 drivers overlaping with total 1.6ohms!) but theese impedance changes and ~1db more eficienty on Diablo may be considered as better for amp.

Elviukai, will you tell me where you found the Diablo's phase shift and impedance curve. I've been looking without success.

I measured it by myself. I didn't noticed electrical phase measurements but I have a frequency and impedanse measuremets in audiomagazines as well.
