Hello from Germany,

syntheticwave · 5th February 2008, 08:20 PM

I am Helmut, working as sound engineer on a German radio station.
Since some years I am build up a wave field synthesis based procedure, to restore the genuine soundfield in all room dimensions physically.
The patented procedure is described on my website in my bad english. Unfortunetally we old east germans has only education in russian, that would increasing the problems possibly.

Regards Helmut

Hello Helmut and welcome to the forums.

Hello Cal,
thanks for your welcome.

Unfortunately I am by the opinion, little speakers are better as big ones.

..but you need a huge amount. Mounted in a smooth plane, tightly spaced. Then you can shift the air by the same efficiency as with the biggest speaker.

On the other hand you can steer differentiated those speakers for increasing frequencies, if you give each of them a own amplifier. On help of DSP´s you can send the wavefronts in desired directions now. And that provides the possibility to reconstruct the spatial structure of the recording room soundfield.
See that Animation, 100 sec. :

But I would agree, you must shift the air in order to generate sound. In that matter you must have a sufficient membran size of course.

That makes it a big speaker.

...and big speakers are better than little speakers. Great big ones are best!!!

I think we'll get along just fine.

Welcome to the fun syntheticwave. You should find no shortage of things to keep you busy for the rest of your life here. I've only been a member since December and I already have too many ideas from this place.

I like BIG speakers also, however my listening space precludes my speakers getting much larger that the Vandersteen 2c's I have now. Cal if you like BIG speakers, I would recommend the Kleinhorns on passdiy.com. I think they would fit the bill.

Cal Weldon · 8th February 2008, 07:50 PM

Yes the Kleinhorns are sure something. Maybe one day...

Until then I will stick with what I had only dreamed of as a kid but was able to acquire as an adult. My avatar is the 'small' part of my big system.

Cheers.

...yesterday i have revise the http://en.wikipedia.org/wiki/Wave_field_synthesis website.
Wave field synthesis is a highly interesting topic. Anyone in the forum can discover hard language mistakes by the site?
