Hi all. I am about to embark on the construction of a purpose built ambisonic studio, which will also double as a 5.1 suite. I have constructed many studios in the past but never one where all the speaker positions have equal importance. Normally with stereo it is beneficial for the sides of the space not to be divisible into each other. The cube being one of the worst examples of this. It is generally better to have the mix position at one end of the longest side of a room too, which helps diffuse reflections before they return to the mix position. Also completely parallel faces aren't good either, (but they also need to symmetrical and predictable) as of course this creates more reflections. Wider and higher at the back is generally a good thing. The general idea is to through all errors behind where they have less importance and where they can lose there energy more. This also applies to 5.1, where front has dominance. The problem I have is that this doesn't seem to a good idea with ambisonics, as the mix position needs to be central and all angle errors need to be equal. This actually leans towards the construction of a perfect cube for simplicity of build, as creating a perfect sphere would be difficult and space would be lost. It will basically be a third order set up, but not sure on the exact amount of speakers yet. I have 4 subs, 25 satellites (120hz roll off) and 10 nearly full range speakers (60hz roll off). Any advice on room shape, and speaker positioning would be greatly appreciated.
