So, my current system is the Denon RCD-M41, which includes the RCD-M41DAB receiver. I planned to upgrade to a whole new system. I’ve settled on the Klipsch Cornwall IVs. I know they’re high efficiency speakers at 102 dB sensitivity (8 Ω). Until I decide and save a bit more for a better receiver, can I connect those speakers safely to my Denon receiver? It says it’s equipped with a 30 W + 30 W (6 Ω/ohms) high-quality amplifier circuit, but also says that you can use speakers with an impedance of 6 – 16 Ω/ohms. I just don’t want to damage the speakers in the mean time, as I know an underpowered amp can cause the speakers to clip, though I probably would never get near the volume for that with such high sensitivity speakers. Just want to get some feedback before doing it. Thanks!
While the impedance of the Cornwall IV’s dips as low as 4 ohms around 100Hz, that small dip is unlikely to cause an amplifier rated for 6 ohms to do anything that would damage a loudspeaker. Just make sure not to play so loud that the amplifier clips, which can send enough energy to the tweeter to cause damage.
