4 Ohm Speaker with an "8 Ohm Minimum" Reciever


I recently put together a small system consisting of a NAD L54 receiver and a pair of Totem Dreamcatchers. The Dreamcatchers are a 4 Ohm Speaker. The NAD Manual states that the speakers should be 8 ohm minimum. Of course, I did not now this until I purchased everything and had all the components delivered. I would hate to sell the speakers, but I am worried I will damage the receiver.
If I use the system, am I risking damage ? The room that the system is in is very small, and the system will be played at low levels. Thank you.

Sfar...What are you thinking!! The smaller wire would slightly INCREASE the impedance seen by the amp and make the load easier to drive. Something else caused the change.
Stanwal...AWG 20 wire is 0.0119 ohms per foot.
150 ft of such wire (75ft round trip) would be 1.78 ohms.
Not really a problem, especially if the speaker is 8 ohms.
