All of this assumes we're speaking of mid and high frequencies. Low frequency reflections off of very near surfaces can cause severe response abberations and need to be absorbed.

Well, the ideal delay is roughly in the 4-10 msec range. Which is dictated by spacing of the speaker from wall and the vector path to the listener. A 2-4' space/distance from the side wall would be sufficient in most cases. However, it is unfortunate that not many speakers will have an off axis response sufficient to make this reflection a real benefit. This side reflection would roughly correspond to about 55-60 degrees off axis response of the speaker, on average, considering typical set ups and slight toe-in. I don't know of many speakers(at any price range) that have a very similar response of the on axis response at such an angle. Typically, at 60 degrees, the off axis is a radically different curve; not ideal.
