May we feel fears about Deviallet Phantom speakers ?

Yeap ! I saw an exhibition at TV News : the boomer are in canceling opposition (one boomer on each side) : I saw the cones had huge movements and for sure there is some EQ, Linkwitz transform and certainly some DSP odds harmonics cancelation like some others bass box makes !

But what I saw is so huge cone movement from the sides cones... (one or two inches movements at least !) that I don't see how it can sound good in bass and mid-bass and have good transcient with two inches bass cones movement! Not speaking of time alignement despite DSP ! There is a lso a deep boomy + 3 to 6 db wall effect because it is wall tied as far I understand !

Strange speaker, maybe it is good I don't know, not listened yet ! but for sure it seems there are a lot of well made marketing and interviewers do not understand anything in sound (not speaking of the specialised reviews like the most serious ones: Stereophile & companies I mean !)

Would be glad to know if it's descent sound as it's a beautifull object ! Because not too pricy as well (digit amp inside) !

To be continued... I believe people will speak about it !

"This next test involves the Aperture Science Aerial Faith Plate. It was part of an initiative to investigate how well test subjects could solve problems when they were catapulted into space. Results were highly informative: They could not. Good luck!"
 
They're quite neat - useful amounts of bass from a tiny box, with a truckload of DSP and amplifier power. They won't do 16Hz at any real volume, though - not enough volume displacement.
They probably do what most subwoofer manufacturers do, and limit the low-end EQ as power demands increase - at 100dB, it might roll off at 40Hz, but 70dB it'll go to 18Hz.


Are there any 8" drivers that'll do similar excursion at reasonable distortion - I wouldn't mind making some litle sub towers for satellite speakers...

I wouldn't be too sure about that ... this, http://en.devialet.com/assets/v2/White-Paper-Phantom-en.pdf, implies otherwise ...
 
They seem to demonstrating it with about the worst choices in music that you can get, for some strange reason - appealing to the young crowd, "this is a super-wow iPod!!!" ... 🙄

Good input imho!

In the TV show i saw, the CEO or the boss of the Deviallet exhibition shop in Paris was saying with a poor Boom Boom music for young people : "Ca envoie, hein !" (I can translate badly by : "It's powerfull like a sport car engine"); And the input given to the interviewer was the one of bad hifi vendors : if they could putt the boomer on your heart at 110 db they would do it !

I believe they mastering with a perfect accuracy the marketing and the targett !

So yes maybe a "must have device" (only) for golden young people who prefer to show more they like listen to ! I don't know... Though this french company seems to have some good ideas (and don't say it as I'm french, the frenchs beings totaly schyzo: not loving what comes from their country : snobs we are 😀 !).

i think it's not the Sphere by Cabasse which are not the same price either 😱 !
