Would it hurt Elite receiver to run 4 ohm speakers

I have a chance on a really good deal for Polk LSi series speakers (lsi7 or 9's). My Elite 443tx receiver (100 watt X7) is stated to run down to 6 ohms. I will eventually get an external amp (NAD, Odyssey), but was wondering if the 4 ohm load would damage my receiver. I only listen to 2 channel with sub (no surround). I know I can find great 8 ohm speakers...but I can get a special on the Polk's
Yes, the Amp could see a load impedance as low as 2 ohms from the nominal 4 ohm speakers.....

I have an elite94vsx. And it won't do well with those polks. It would sound anemic at best. I use it for pre-pro with a sherbourn 5/1500 with my nht setup. They mean it when they recommend 6 ohm min
I have a 92TXH, quite similar to 94TXH, and I have been using it with 4ohm or lower speakers. in fact, very demanding load (Sonus Faber Amati Homage and Aerial 20T). I admit my hearing becomes semi-deaf when I watch movie, I also admit I don't play that loud. so far the 92TXH seems to hold up well, do not run hot, and sound decent even with Aerial 20T.
