With the omnidirectivety paranoia many people might loose from attention that fact that in order to be good omnidirectional speaker the RAAL new speaker has to be just a good conventional speaker first. The new RAAL speaker (does it have a name?) as I can see is 3 way design with very restricted back chambers at MF and LF. The selection of the drivers MF and LF to work in this condition and the way how Alex used them is very interesting subject. I do not think that Alex shell be talking about it to listen if the result is appealing shell be very educational.

There is one interesting point in the new RAAL even regarding the omnidirectivety. All omnidirectional speakers I have seen had omnidirectional higher frequency range. RAAL is omnidirectional full-range. It shell produces very different result and I do not know which one. It might be also very interning idea to turn on and off (or even to using in back-phase) the back/side firing HF and MF drivers, letting the dispersion diagram of the speaker to “read” the room. I can see a remote control that would allow resetting the individual drivers in the new RAAL speaker, while the speaker is playing…

Do you what more fantasies? How about this “remote control” automatically and dynamically complies with the delta of stereo separation that sent to right and left loudspeaker. This idea combined with my idea of RT60 emulator might be a fun direction to play with.  Also it might be interesting to to make a large parabolic reflector, locate them behind or on the side of the new RAAL speakers and to see if it is possible to “spook focus” of the speaker in some atypical way.

We spoke today with Alex about his omni-directional idea. I have to admit that I did not “get” what he was trying to accomplish and I had very skeptical attitude toward to it. I was feeling that Alex moved toward to this omni idea juts because he can. To my surprise it was not exactly true and Alex had a very consciousness objectives what he was trying to accomplish with this new speaker, BTW the omni-directionality is not all that they have. I kind of overlooked behind the omni-directionality some other aspects and from Alex’s explanations of his objectives I conceded that I might understand the whole omni-directional idea a little bit too narrow. I think Alex need to do some education of public about what and how his new omni-directional version meant to be used.

I have to note that even understanding now the Alex’s objectives in the omni-domain I am not convinced that I agree with them. I would say that those views might take place and have reasonable bases but how “winning” they are it very difficult to say at this point. It is very possible that with his new speaker RAAL stir up much bigger question then it is on surface? Well, I would not spoil the trailer and let Alex to talk about his views, when he will.

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.
