Highlights：
• I deal with a mixed problem for the multidimensional wave equation with delay.
• The exact series solution is constructed by the method of separation of variables.
• The time-dependent functions of the decomposition satisfy second-order delay differential equations.
• Explicit, closed-form solutions are sought.
• The literature on closed-form solutions for delay wave models is improved
