I don't know anything about how to match the receiver and speakers and need some help from the experts.

I just purchased a new receiver and want to use it with a set of speakers from my previous system. The speakers are:
FSs: 2 way 3 speaker; 4 ohm; 155 W (max. 310 W)
RSs: 1 way 1 speaker; 4 ohm; 155 W (max. 310 W)
CSs: 2 way 3 speaker; 4 ohm; 155 W (max. 310 W)
Woofer: : 1 way 1 speaker; 4 ohm; 225 W (max. 450 W).

While the receiver produces continuous power output 6 Ohm with Front 150 W +150 W; center 150 W, Rear 150 W+150 W.

I would like to know if they are SAFE to use my speakers with the receiver and the receiver won't "burn" the speaker.

Thank you very much for your help.

A few points to watch...

Although 'Watt' is a well-defined engineering unit, many marketers take liberties and use 'variations' (music power, peak power, etc) to inflate their equipment's specifications. So take care that the speaker power rating and receiver power rating are both specified as RMS watts.

Secondly is the impedance rating. Your speakers are 4 ohms, and the receiver is rated for 6 ohm (from what you've given us). That's not to say it won't happily work with 4 ohm speakers. You may need to delve deeper into the receiver's specification to see if they state the 'minimum speaker impedance', or whether they give a different power rating for 4 ohm speakers.

In any event, if both power ratings you've given are in RMS watts, I can confidently say that you shouldn't damage your speakers with that receiver. If the receiver is not rated for 4 ohm speakers, there's a small risk that you could damage the receiver, but if it's fairly modern that's unlikely, as they tend to be reasonably well protected against excessive speaker loads.

Thanks.
