The logic behind the Focal Diablo Utopia's SLANTED SPEAKER DESIGN?compared to flat...

aarvin2 · 17th December 2012, 09:56 AM

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 ??

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.

If the top tweeter enclosure is adjustable, then it is a "feature".

Also it is a "reason" to charge more.

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.

Could be interesting when sitting right at the sweet spot and at the right high only.

But it makes no difference with regards to the sound AT ALL?

Should have some influence on floor/ceiling reflections?

Hi,

IMHO any technical analysis is futile, any real benefit is far
outwayed by the cost of incorporating the "tunable" feature.

Said feature is easy to understand visually for the clueless,
and that is the point rather than any technical advantages.

rgds, sreten.
