Thank you Cusp for that lovely information though it was bit more technical to me.
I dint understand: (to gain more control of where your cross-over points are (keeping the sub-bass out of your mains, and vice-versa) helps the speakers give optimal performance (when adjusted correctly).
Did you mean by using LMS,
a. I can increase the volume with less energy
b. I can save the speakers quality output
Please advise
