I have two Webern front speakers connected to a Yamaha RX-2080 amp. I recently purchased a Klipsch 5.1 “Reference Theater Pack” for the back surround speakers, the Atmos capability. So I have two front speakers that are not hooked up. Is is worth impedance matching those 8 ohm speakers to my Webern 4 ohm speakers. Yes, more sound but better sound? Webern speakers are 60Hz-25kHz, 91 dB, 30-200 Watts (2-way system). The Klipsch are sensitivity: 91 dB, power handling: up to 50 watts RMS. Any help would be greatly appreciated.
