Mapleshade/Pierre Sprey has long made and sold special speaker stands that elevate small box loudspeakers only about 2". He says such siting outperforms the same speakers at normal recommended listening height.
I have long wondered about his unique siting recommendation. It just occurred to me that besides the bass reinforcement, such siting increases delay for ceiling-reflected energy by time length equal to the stand height. A speaker lowered from 24" to 2" increases delay of ceiling reflections about 1.8ms.
If Peirre's stands work, I'd not be surprised if much of the benefit comes from 50% greater delay for ceiling reflected energy. 50% is likely an audible improvement when starting with an original delay time of only about 4ms sited on normal height stands.
