If set the receiver's impedance at 6 ohm so I can plug in a 6 ohm speaker, can I still use the 8 ohms speakers at the same time?

I'd leave the selector at 8ohm and run the mix of 6 and 8 ohm speakers. It should be fine. The only way you'd run into a problem is with 4ohm speakers, and in that case you should be using a discrete amplifier.

i have this receiver and love it. I power 3 zones with it. All you need is speakers for zone 2 and 3. No additional amplifiers needed as all 3 zones are powered by the receiver itself. if you run 2 sets of speakers per zone, make sure your speakers have an impedance matching the receivers impedance. Do your research about how to connect them to not generate the wrong impedance. Connect speakers in series: add up impedance and you are on the safe side. If your wiring does not allow to connect them in series, make sure each of the 2 speakers you connect in parallel have double the impedance than the minimum impedance your receiver can support. Example: minimum impedance 8Ohms means you could either run 2 speakers each 4 ohms or higher in series (totals to 8 Ohms or higher) OR 2 speakers 16 ohms or higher in parallel (totals 8 ohms or higher).

The manual says the speakers should be between 8 and 6 ohms impedance. You probably would run the risk of frying the output amplifier by overloading it at 4 ohms.

Two 8 ohms speakers in parallel make a 4 ohms load. If you have 4 speakers you'll have to wire 1 set of 2 in series wicch will give you 16 ohms and set 2 in series also. Two 16 ohms wired in parallel will make an 8 ohms load

As long the impedance match or at least it's in the functional range you should not have any problem, this speakers are 8 oms . If you receiver it's 8 oms or work from 2 to 8 oms you are good to go . However is not recomended connect speakers with different impedance together . With that say it if you others speakers are 8 oms too you won't have any problem at all

Maybe. The more speakers that you connect the lower their effective impedance as seen by the amplifier. And the lower the effective impedance the higher the current that the amplifier must generate in order to drive the speakers to a specific listening level without distortion. Most speakers, particularly the less costly ones, have a nominal 8 ohm impedance. So if you are driving one set of such speakers the amplifier will be seeing an 8 ohm load. But if your amplifier is driving 2 sets of such speakers the amplifier will be seeing 1/(1/8 + 1/8) = a 4 ohm load; if your amplifier is driving 3 sets of such speakers the amplifier will be seeing a 1/(1/8 + 1/8 + 1/8) = 2.7 ohm load, etc. With 6 speakers your amplifier will be seeing a 1.3 ohm load. And this would be a nominal and typically maximum load; in practice the load fluctuates depending on frequency and is effectively lower for short periods of time. Some amplifiers are designed to drive such low loads but many are not. If you try to do that with such a low current amplifier for a long period of time you will burn up the amplifier. That is why speaker selectors like this one have a protection button which basically adds a resistance in series with the speakers in order to increase the impedance seen by the amplifier. This will reduce the overall efficiency and you will notice that you have to increase the volume to get the same amount of sound as with the protection button off. So, if your amplifier has a sufficient current capability to drive those 6 speakers to your desired listening levels, great. If it doesn't, and if the listening level is too low for your tastes with the protection button on, you will need to either settle for lower volume or get a more powerful amplifier.

They're supposed to be 4 Ohms even though the back says "4/8 Ohms" but in reality they're less than 4 Ohms - a tad under 3.5 Ohms. unless your amp/reciver can tolerate resistance of 2 Ohms which very few can, don't wire them in parallel with an 8 Ohm speaker. I did and it almost fried my receiver.

yes they can, but you need to be aware of the Impedance. if you daisy chain 2) 8 ohm speakers you get 16 ohms if you parallel them you get 4 ohms

There is a setting on the 573 to set speaker impedance to 6 Ohms. See p 80 of the owner's manual.http://download.yamaha.com/api/asset/file/?language=it&site;=it.yamaha.com&asset;_id=54064

Per manual, page 14, "Setting the speaker impedance" (USA & Canada models only): "under its default settings, the unit is configured for 8-ohm speakers. When connecting 6-ohm speakers, set the speaker impedance to " 6 Ohm MIN." In this case, you can also use 4-ohm speakers as the front speakers". Hope this helps.

Should be fine if they are 8 ohm speakers. I think RX-A2020 amps are overrated for power but I would not use it with 6 ohm speakers.

Using two 16 ohm would be the same as using four 8 ohm. You would be getting about 30 watts of power to the speakers. That is not much!

The receiver can easily drive 4 ohm speakers. The RMS power rating of 80W applies to 8 ohm speakers, so the power output for 4 ohms will be somewhat greater.You can change the speaker impedance from the default setting of 8 ohms to 4 ohms using the "Advanced Setup" menu as described on page 37 of the owner's manual.

Mr. Garrett - Technically this is a 2-channel Amp. You can easily wire 2 pairs of speakers to it however, and alternate between the two or run them simultaneously. I have run 4 6 ohm speakers this way without issue and it played plenty loud. I imagine you could easily run up to 3-4 pairs of 8 ohm speakers in parallel this way, or more if you ran them in series. But it would be safer to make sure that you used the same speaker if you were going to start hooking up tons of them (because the impedance of each would be about the same)!If you wanted to run multiple speakers off the amp, like the other responder, you could do it, provided that you keep the impedance above the 4 ohm minimum.

What is your receiver's impedance rating? If you run at least two pairs of 6 ohm speakers then you must activate the protection switch. Check the impedence of your speakers at http://www.nilesaudio.com/techsupport/calculator/index.php

I believe all the new harmon kardon radios have two ohm speakers I would keep the impedance the same I think they started in 2008or 2009 till present

No problem at all. Also for future reference, say if you have an amp with four and eight ohm binding posts, just wire the 6 ohm speakers to the 8 ohm posts and rock and roll!
