Omni directional speakers

the gradient revolution is adaptable to any room too.

The Gradient Revolution and Helsinki both have exceptionally smooth power response (something a good omni also achieves), but the design goal is radiation pattern control to reduce early room reflections, rather than omnidirectionality. In my opinion one of the primary advantages of an omni is its smooth power response, but there are other formats that do a very good job in this area - the dipole/cardioid/waveguide Gradients being among them [dealer disclaimer]. In fact, there are dipolar and bipolar speakers whose characteristics more closely approximate an omni than the Gradients' do. The Genesis Model 5 and its descendents come to mind - though not technically an omni, its presentation leans in that direction.

John Huff makes custom speakers using the German Physics DDD driver.

Long-gone Design Acoustics used to make a big quasi-omni soccer-ball-on-a-pedestal. Epicure/EPI also made quasi-omni speakers that had a midwoofer and tweeter on each vertical face of a large columnar tower.

Pedrillo, could you explain what a semi-omni speaker is? I was not aware of the design. I thought a speaker was either omni-directional, or not...but not somewhere in between.

Duke, thanks for helping.
I thought the gradient was forgotten.
Duke, what do you think of the bolzano design, that is the design I will attempt to build with some pro help.
I have been playing a mock up of that design and like it very very much.
Any suggestions would be appreciated, I expect lots of tweeking and fixing before it gets anywhere near good.
I will biamp at first to be able to control the tonal balance.
I am considering scanspeak drivers, but accuton may be an option. Should I seek out a wide dispersion tweeter?
Midrange/woofer are generally wide by nature,true?
