I am considering buying the Denon 5805 for a home theater room I am in the process of building. My concern is that it will not be able to drive my speakers which are 4 ohm. The speakers are the Polk LSI series: Fronts - LSi25, Center - LSiC, Sides- LSiFX, Rears - LSi9, and subwoofer is the Velodyne SPL 1200. Does anyone have any experience with the 5805 and 4 ohm speakers? If so, any advice would be greatly appreciated.
I have not been so fortunate with 4 ohm speakers. Denon specs are quoted at 6 ohm minimum for a reason. There manual reinforces this. My centre speaker is nominal 4 ohm but drops below occasionally - It tripped the protection circuit so many times I had to interface it with a transformer to present an 8 ohm load to the amp. Most one box av solutions would be the same however.
My ultimate solution was separate power amps.
