Thinking about getting Paradigm studio 100's for front speakers. Get either paradigm cc-590-, or cc-690 for center channel. Keep left and right surround, and left and right rear surround speakers, for now. Have polk audio rtia3 for left, and right surround. Polk audio fxia4 for left and right, rear surround. Fxia4 are bipole, dipole design.Eventually replace surrounds, can't replace all of the speakers, at once, due to budget. How will it sound, with mixed speakers? Notice much of a difference? Mainly watch movies. If i listen to music, usually use 2 channel. What is the percentage of sound, coming out front three speakers, verus surround, and rear surround speakers, during a movie? Really appreciate your advice, wisdom, and suggestions.
