Home Audio Question about Impedance
Hmm, sorry for posting a "home audio" question when this is mainly a car audio/electronics forum. But, I know you guys can answer this, and I have really no one else to ask. Its a simple question. If I were to buy a center channel speaker that is "6 ohms" but my reciever's RMS is at 8 ohms, what are the losses or issues? Thanks for your replies. (I'm a pure n00b at this, lol, I'm slowly learning)

Its pretty simple. Ohms are a measure of electrical resistance. The higher the OHMs, the MORE resistance the amp will "feel." When the load is decreased, for example, 6 ohms instead of 8, the amplifiers power output will increase, due to their being less resistance to the power coming from the amp.
Most high quality amplifiers can drive loads at lower resitance levels. I am pretty confident that the 6 ohm center channel speaker would cause zero effects on your amp, since I've driven a lot of home theater stuff down to around 4 ohms with no damage.
If you check your amplifer manual, there is usually a MATRIXED chart, showing the different power outputs based on resistance levels.
I am running 2 speakers that are 4 ohm on my Onkyo. I can push the amp to the limit, but when I tried it on a Sony the proection circuit came on. 
Under normal sound levels they will sound great (much louder than 8 ohm speakers) but the quality of your amp will determine how much you can increase the volume.
You should have no problem.
Moral of the story = Sony sucks, Onkyo awesome

I have an Onkyo 200w two channel receiver, nothing fancy that drives two Polk RT16s and a 250w amplifed Polk sub usually at 3/4 output with no issues/clipping etc. I've also driven speakers at 2-6 ohms with no output stage issues, apart from the top getting a little warmer than normal.
