I always thought there are only two basically interesting approaches to the sound reproduction:
- eliminating the room effect as much as possible with a controlled disperssion of a forward firing horn
- or completely include room (a bogus idea, I know) by means of omnipolar radiation pattern
(example below, Duevel Loudspeakers with omni radiating compression drivers) or bipolar radiation pattern (identical set of drivers firing forward and backward)
Everything that falls in between those extreme categories, gives mostly inconsistent results (uneven power response).
But we`re talking about large differences here, if a forward firing horn sound could be described as "dry" (my impression), then an omnipolar horn
gives me sort of a "wet" impression of sound (soundstage appears very "airy", sometimes too much).
Personaly, I`m leaning toward that "drier" presentation, which gives more immediate presence and the "airyness" could be enhanced with a wider disperssion tweeters (very short, wide angle horns or direct radiators).
