A reflector and an electronic system produce a diffuse way by creating time delays in accordance with a number sequence. An acoustical passive reflector incorporates a series of wells in its surface to transform an acoustical wave into a series of acoustical waves having a time difference based on a number sequence. The electronic signal conversion system converts a signal into a series of signals having a time difference based on a number sequence. This can be used in an audio speaker system having N×N array of speakers where N is an odd prime number, arranged to be driven by the electronic signal conversion system in which the signal is converted into a series of signals centred on the signal with at least one signal being timed to precede the signal and at least one signal to follow the signal and the signal being arranged to be sent to the central speaker in the N×N array. 126-. (canceled)27. An acoustic reflector for reflecting acoustic waves radiated from a source , the acoustic reflector comprising: {'br': None, 'i': D', 'n', 'N<=N, 'sub': 'n', 'sup': '2', '=(rem N)*unit depth, O<=−1,'}, 'a surface, facing the source, having a plurality N, where N is an odd prime number, of wells with each well having a depth of'}wherein the surface has a length direction, the wells have bottoms, and the wells are, at the bottoms, parallel to one another in the length direction, and wherein the tops of the separating fins between the wells are acoustically fluted.28. The acoustic reflector claim 27 , as claimed in claim 27 , wherein the bottoms of at least some of the wells are concave.29. The acoustic reflector claim 27 , as claimed in claim 27 , wherein the bottoms of at least some of the wells are convex.30. The acoustic reflector of claim 28 , wherein the wells are claim 28 , at the surface claim 28 , parallel to one another in the length direction claim 28 , and the surface is oriented with respect to the source such that the acoustic waves from the source and the length ...
