I am currently using a Yamaha RX-A710 receiver with Paradigm Cinema V.1 center channel and front speakers. The speakers are almost 20 years old. I want to improve the quality of voice while watching movies and TV. I have adjusted the receiver trying every option to improve voice, but there are still times the voice comes out muddied. While I am overall happy with the sound from the speakers, outside of the voice, I am wondering if I could improve voice by replacing the speakers. I am thinking of something like the Klipsch RC-250C for a new center channel. The Paradigm center speaker is pretty small, 12x4 inches. I am not sure if I should also replace the Paradigm front speakers to keep them matched to the center channel. Would I see a significant improvement in voice quality with the new center channel speaker or would I have better sounding muddied voice?
