Can my receiver handle these new speakers?

[Gannon]

Hi all,
I’m a beginner and I'm looking to upgrade my home theater system, which is a Yamaha RX-V383BL receiver and some beginner home theater speakers.

I'm looking to upgrade the front, left, right, and center speakers so I ordered Polk S15 and Polk S30 speakers. Can someone help me understand what the rate output power means and if my receiver can handle the new speakers I ordered? I’m not sure what all the specs/wattage mean so I was hoping you guys could help guide me. The receiver and speaker info is listed below:

Yamaha RX-V383BL:
Rated Output Power (1kHz, 1ch driven): 100 W (8 ohms, 0.9% THD)
Rated Output Power (20Hz-20kHz, 2ch driven): 70 W (8 ohms, 0.09% THD)
Dynamic Power / Ch (Front L/R, 8/6/4/2 ohms): 110 / 130 / 150 / 180 W

Current speakers:
Front/Center/Surround Speaker Input Power (Max/Nominal): 100 W / 30 W
Subwoofer Dynamic Power: 100W

Polk speakers I ordered:
Polk S15 (Pair)

Polk S30

Any help is appreciated. Thanks!

Wattage ratings for speakers are more about max levels before things start to go south. Sensitivity and impedance are more important specs. Try this article https://www.audioholics.com/loudspeaker-design/truth-about-matching-amplifier-power

Your avr should be fine with those speakers for the most part, but somewhat depends on how far away from the speakers you are and to what levels you want. You might also try this spl calculator http://myhometheater.homestead.com/splcalculator.html

When it says receiver's power output is 100 w (ch driven) and 70 w (2ch driven), is that for one speaker, or all the speakers hooked up to it?

At what point do I need to worry about damaging my speakers or getting poor sound quality due to an incompatible receiver?

It's a rating as to how much power your receiver's output can sustain under different loads....the higher figures come with lesser loads. You could perhaps exceed such ratings with poor use of the volume knob, but that's usually easily managed by just keeping it to what sounds good. It's not a matter of a receiver being compatible, the whole point of components is interchangability/intercompatibility. Not consuming large amounts of alcoholic beverages could help avoid damage....

Truth.

Truth.

But that's when my gear sounds the best - the neighbors agree!

When you hear distortion or breakup you're risking damage and it's too loud. Sound quality has a lot more to do with the speakers than the power supply.

To answer the question more specifically, it is rated just as it says, it can output 100w with just a single channel driven, and drops to 70wpc with 2 channels driven, but it does not provide an all-channels driven rating, but it would again be lower. For many avrs will generally be in range of 60-70% of the 2ch rating for all channels....but that is not a very important consideration as content won't have equal demands in all channels simultaneously (except maybe an explosion in a movie or something like that).
