Speakers with no rear wall, better or worse sound?


I have been in a debate about speaker placement. I was proposing that having speakers in the middle of a long space (~30 foot long room) would be preferred over having speakers about 3 to 4 feet from a wall behind the speakers. I would think that having little to no wall reflections of sound from behind the speaker would be preferable. The wall behind the speakers is currently about 14 feet back. Another opinion suggested that we should build a wall 4 feet behind the speakers to get the best sound. I was thinking that the reflected sound from this new sound would mix with the speakers' direct sound and erode the quality. Other views? We were considering some renovations and I do not want to go through a significant change to our home and erode sound quality.

Problem is that 'accurate reproduction' is such a moving target, especially when most recordings are hardly 'accurate reproductions' of a live event in the first place. Most recording efforts to produce accurate recordings come from classical music department but it only works there when well engineered performances are small scale which seems to overcome some of effects of the compression and downsizing of larger orchestral events. So it is a compromise. Even most soundstaging effects having their orgins in the recorded music, as opposed to set up, are artificially recreated by mic placement which often gives undue prominance to some instruments which is something you never hear in concert. But it sounds nice :-).

So, I would also make a case for the thought that 'if it sounds good to you, then it is good' because sounding 'real' is virtually impossible anyway, and faithful reproduction of what is on the disc of the majority of the music you listen to may not really be what you want to hear. The exception to this may be the few really anal audio enthusiasts who really do want a perfect chain, cradle to grave and they listen to principally train wistles and jets taking off. :-)
There's no right or wrong, hard and fast answer. Try the speakers in the different positions and see which you prefer.
So I guess another angle on the original question would be: if you could change your room dimensions or characteristics to improve the sound, what would you do...no rear wall or putting in a rear wall.
I'd think that there will likely be (at least) 2 audible effects:

Overall bass response will likely be attenuated as room re-inforcement from the "front" wall is eliminated.

Bass response should be smoother as frequency specific destructive interference from reflections off that wall are eliminated. (There will still be some destructive effects from the other walls, floor, and ceiling, but that wall is often the worst offender.)

As to the "better or worse" analysis of the net impact, that will be case specific and will turn, in part, on whether there'd be too much or too little bass from that speaker in that room, with the missing wall "restored".

Good luck.

frankly it sounds ideal for a Maggie

they love to be away from walls

IMO YMMV of course
