Hello. I'm planning to get the M&K Sound M-5 Satellite speakers for my home theater. The only problem is that they're 4 ohm speakers. My current Wharfedale Diamond 220 speakers are 8 ohm and paired with the Denon avr-x2300w. I will sell that receiver and get a new one. Probably a 9.2ch avr. My only options are the Denon avr-x4500h and the Yamaha rx-a2080. Will those receivers be able to handle the M&K M-5 speakers in a 7.1 or 9.1 setup? The M-5 technical specs states that it needs 25 - 80 watts of power and the sensitivity is 84.5 dB. If I have the extra money then I might get the M-7 for the front LCR and the M-5 for my side and rear surrounds and perhaps front height if I want to do a 9.1 Dolby Atmos setup. There are no multichannel amplifiers available at my local store so I won't be able to use an external amp.
