Semi omni works with the room and fills the room with sound unlike point & squirt. You can walk around the room and the sound is much more consistent. You get more direct radiation from a woofer that is upfiring when you stand up but move out of the direct wave from the tweeter. It is a shame that small dome tweeters are so directional but you cant change physics.
So how do we get even more room filled sound with no hot spot - you can sit anywhere and it sounds the same ? Is it even possible ? The doc had respect for Shahinian. Whilst not true omni they do have tweeters which do not fire straight at you. Many fire up at 45 degrees so you get a lot of first reflection off the ceiling. The obelisk has multiple tweeters firing in different directions .
So the way forward for me seems to point towards pseudo omni with all drivers pointing in directions other than straight at me. Sod the imaging. I want to enjoy the music regardless of which sofa i slob on. I don't want to have to put expensive and ugly room treatments all over my room. No disrespect to anyone here that uses dsp or other eq but i don't want to have to resort to that either.
What was my point ? Can't remember now.
The Cubes come close to this effect, with a different form of presentation but with more 3D-depth and considerably more dynamic punch and 'life'.
