Distruive interference? Unless you put C in the line between A and B, this the asnwer is at infinity.
Now on the line between A and B, the distance from A to C has to be an odd multiple of halfwavelength greater than C to B. Now, the distance between the speakers is two wavelength. So if ACBC is n lambda/2, then n must be one, so
AC=BC + 2.54/2 where BC= 5.8AC
solve for AC.

Please tell me where I am going wrong.
AC = BC + 2.54/2
AC = 7.366
AC=BC + 2.54/2 where BC= 5.8AC
AC=5.8AC + 2.54/2
2AC= ... solve for AC.
