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.

Some well intended but misinformed suggestions here with reference to the goal of Avalon Acoustics. I think you already understand the basic principals of thirds as described in the Avalon manual when considering your own room.

As simple as it's described in the manual, if like me, you're dealing with an irregular shaped room it will take a degree of trial and listening. The right recordings and speaker mobility during this period of adjustment can be your biggest asset.

After months of this I was sure I had found the magic placement only to have a friend who is very experienced with Avalons separate the speakers a few more inches and add 1/4" of toe-in and bingo. The sound stage seemed to surround as if the timing of reflection found the listening position optimally. In the end it takes someone who has experience with the particular speakers potential to wring the most out of your room.

The affect this had on the speakers bass was also a result of timing and not about an increase or decrease in bass. In my case (or my taste) the addition of two small Velodyne subwoofers to blend seamlessly and control the lowest octave also had the effect of adding size to my room.

Good luck with it.
