*Call* the company directly. I don't see anything much besides CNET & ebay on that model speaker. That must be either the incorrect model number, or some sort of older product/re-branded speaker system. YMMV.

Also, read through the basics of impedance matching here:

I have 4 sonance tr 3000 ceiling speakers. I posted on another forum about my speaker troubles. Somebody said they are 4ohm speakers. But these cnet links says 4/6 ohms.

I want to buy a new receiver instead of messing with an amp or anything else. But want to make sure before I buy one. My current is 8ohm and is not compatible. So I want to make sure.
So it is 4 or 6 ohm? Or does 4/6 mean it can handle both and I don't need a 4ohm reciever (yes pyle makes some like PT590AU is 4ohm). If its 6 I can buy a 6 otherwise I have to have 4. So is it 4 or 6 ohm. Anyone know?
