Some pictures of the omni-venture

I actually like the picture of Alex standing on his speaker more then I like the picture of a woman on couch.  A bit too well made photography for a regular AV blog.

Omni

I can´t see a horn,
in bass omnidirectional? stupid?
Did you see a measurement of the box?
look like a bigger B&O, and needs a difficult activ solution to get bass, like B&O
it is material overkill with out a win of sound.
My experience shows in listening rooms a omni over 1,5 kHz
isn´t wishable.

I don’t know what stupid is in this case. I do not like the omnidirectional idea as well but I would not mind to listenen them in a well controlled by me environment. I would be very interesting about imaging from the omnidirectional loudspeakers. I do not care about their bass quality, material overkill, tone or any other things. The imaging of omnidirectional bass radiated from a single point might be also very “interesting”. This is one of the examples where it is very difficult or even impossible to predict the thighs and there is no point of reference and and you need to listen the thing. The omnidirectional German speakers that I heard were not omnidirectional-demonstrable as then has “strange” omnidirectional drivers that I found controversial.

stupid? no not known?

Bass are between 3,4 m up to 20 m long waves, ear brain can get it after
the 4th wave, so 40 Hz is than 32 m and ~100 msec on the run, after you get it,
if i see a standart living room dimension, there is no omni left for bass.

There is a difference between guessing and predicting.

moreart,

It is the theory that you feel comfortable with but I am not. If you compare a radiation from a single 40Hz transducer and a dipole 40Hz transducer then you will recognize the differences.  Also, you look at the 40Hz but I ma talking about a wide-bandwidth omnidirectional sound, including bass. I do not think that the Omni-RAAL bass in will be competitive with other bass-topologies from a perspective of “absolute bass quality” but I do think that it might be interesting to observe this bass in context of full-bandwidth omnidirectional sound. It would be interesting also to shut down the Omni-RAAL woofers, substituting them with conventional LF sections and to observe of the single point omnidirectional bass has any meaning in the context of total omnidirectional sound.  I can easy make surprisingly accurate predation in many cases but it is only if I have a proven to myself point of empirical references. In the case of omnidirectional sound I have no such a res and therefore I feel that listening the new Omni-RAAL might be very educational.  From what you say I conclude that you also have no empirical references to the omnidirectional results.

HI,

dipol bass, not happend in nature,
yes different listening, because of reflections,
below ~300 Hz the listening room is dominat,
you listen more the room, not the single driver.

If you look my horns, the double horns,
you can see my OMNI-bass experience.
