Having listen to box speakers all my life, personally I prefer listening to a good omni. When done right it doesn't sound like you are listening to your room and if you haven't heard it you won't understand. Some think that Omni's means vague and reverby sound and imaging but it's absolutely not the case.
From the Fremer review...
The problem with discussing omnis of the MBL type is that few people have heard them outside of a crowded hotel room at a show. This leads people to theorise about how they think they will sound, some even refer to the manual of a speaker which has an omni effect to make their erroneous points. When well set up, and not everyone will have enough space, they give superb imaging and a realistic, holographic, sense of the performers playing in front of one like no other speaker type I’ve tried. They are not ideal, perhaps, for those who want to replicate what the engineer heard. They are best, however, for anyone who regards high fidelity as a realistic recreation of the original performance. All a question of taste of course.Having listen to box speakers all my life, personally I prefer listening to a good omni.

From the Fremer review...
"No box above the bottom octaves and a 360° radiating pattern should produce imaging and soundstaging superior to that of any boxed or planar speaker, and once the speakers had been placed properly, the 101E Mk.IIs did just that, reproducing with eerie verisimilitude recordings of large orchestras as well as of small ensembles in intimate settings, such as a superb-sounding reissue of Johnny Hartman's I Just Dropped By to Say Hello (LP, Impulse!/ORG 176). The sound was intimate and properly sized, and produced Hartman's baritone with a natural warmth free of congestion or bloat.
Going back to some of the live Carnegie Hall tracks I listened to for my 2004 review reinforced the 101E Mk.IIs' astonishing spatial abilities. The speakers' presentation of physical instruments and musicians in space required no suspension of disbelief—the holographically three-dimensional picture was just there. The Weavers' Reunion at Carnegie Hall 1963 (single-sided 45rpm LPs, Vanguard/Classic 2150) was reproduced with the singers arrayed holographically across the stage. The images of Ronnie Gilbert's and Pete Seeger's voices and the glistening acoustic guitars were as convincingly portrayed as I've heard them here, including the toe-tapping, the wooden stage floor, and the airy, open space. Lights out and you're there!"
Now contrast this with a wide directivity speaker, you are now basically bouncing treble off the side walls, floor, ceiling etc and the delay between direct and reflected sound becomes far shorter, more blurred, and harder to pick apart.
It depends on what you want.
Except instruments have very different patterns...

For the theorists who talk of secondary reflections, I think they need to consider the time delay, and reduction in volume between them and the direct sound. Then there’s the tricky bit; assessing how the brain differentiates between direct and secondary sound and how it recreates the information to reconstruct the music in our minds.
There are compromises to be made in that they need to be situated away from walls and also that they are bloomin’ expensive, Worth it though for my ears!
They do, but nothing beams sound like a very directional Hi-Fi loudspeaker does. Even relatively directional instruments like the ones you mention can be heard perfectly well from the side. This isn't true of some loudspeakers.
It depends on what you want. Very directional speakers can paint you a picture of instruments in the distance but if you want the illusion of solid instruments in your room then wide dispersal mimics the sound of real instruments better.
650Hz is quite high for a trombone...
Have you ever listened to a flute, an obeo or a trumpet played live?

Quite often. Orchestras, jazz bands, quartets and other small combos, many times in many circumstances. Church groups, on the street, in people's houses....
All this talk about direct vs reflected sound and yet, no love for the Bose 901?
This might work for recordings which are studio constructs; for recordings which are intended to be reproductions of the sound heard in a concert hall, I am not convinced....I want the studio control-room sound as it is the only ‘real’ on offer. I want to hear the decisions the engineers made...
