Hi guys,
does anyone know why the flagship Focal Diablo Utopia uses a slanted design for it's woofer and a straight flat face for its tweeter ??
This thing costs 8000 USD a pair.
The lower priced Electra 1008 Be, has a lower price(5000 USD PER PAIR), is not the top of the range, and uses a COMPLETELY FLAT fascia.
Could anyone please care to explain why the top of the range DIABLO uses the slanted+flat fascia while the lower range uses a completely flat fascia??
What is the logic behind the Flat tweeter and Slanted woofer design ??

An externally hosted image should be here but it was not working when we last tested it.

Hmm,
my guess it for its effects on baffle step response, dispersion pattern, and aesthetics. Maybe it's adjustable.

Lol! Aarvin, for some reason your choice of topics and your timing seem to attract my attention. I didn't even notice this was your thread until after replying.

Hi,
Its a USP "unique selling point" applied to all the top models regardless of logic.
rgds, sreten.
At this point a proper technical analysis is futile, its a striking visual feature.
But it makes no difference with regards to the sound AT ALL?
Steen Duelund: "All units must be in phase at all frequenzies"
This is ensured by:
- phase-coherent x-over (the "syncronig filter") (for this to work as intended, all units must be impedance corrected to DC-resistance)
- aligning the units´ acoustical centers to perform a circel from the listening point:

(also check speakers from Gryphon, Wilson, Pass, earlier B&O, B&W and several others)

It's time alignment of the drivers. A very common feature in technically advanced loudspeakers. The idea is to get a nicer integrated result with simpler filters. 
No surprise that people liked the B&W DM2A floormounting speaker:
Or the more recent Sonics Anima by Joachim Gerhard:
I'm sure it IS futile here to give a technical analysis, but I like doing this sort of thing:
Quite how you reconcile that with the characteristic notch of inverted polarity on the tweeter or the order of the filter, I leave to the Interested Student.

Which as long as the drivers are not physically coincident can only happen in one listening position.

Oh, aren't you clever to figure that out! Special subject for Planet 10 on Mastermind tonight, THE BLEEDING OBVIOUS!
BUT, you could do a time aligned D'Appolito...

Very nice, IMO.
Yes, NOD'S as good as a wink to a blind horse an all that.I have a more concise way to explain what it does: change the polar response.
I was VERY IMPRESSED when Michelino at this forum produced his box design:

This kid's got a future.
To you and me and many others, but not all.
Driver C-C needs to be 1/4 wavelength or less at XO to be acoustically coincedent.
