Will this unit drive 4 ohm speakers? Any problem doing so?

J. Michael Pisias Jr., Good evening. I just pulled up your question and I am willing to guessthat this amplifier is capable of driving 2, 4, 8, 12 ohm speakers as directed by the purchaser.The reason for my positive response, and I am driving Bose 301's and rebuilt Infinity 3000's, isthat any speaker set up is not a mix and match situation. Go with the speakers you have installedbut do not cross/mismatch the ohms; a quick check of each speaker will save you trouble down theroad. I believe that I am running, 12 total, 8 ohm speakers which I play at volume 50-60. My Jazzsounds terrific! J. Michael Pisias Jr., Good evening.

It will, but I wouldn't push the receiver too hard if you do (moderately high volumes are okay, but not for sustained periods. The receiver will shut itself down if it feels theres a problem). Make sure to have VERY good ventilation around the receiver also. It is gonna want to get hot because of the low ohm load. You can also get some 50watt 4ohm resistors and add them to the speaker to increase the impedance if you really want to play it safe. Hope that helps. I know it's not the answer a Marantz engineer would want me to give, but I'm a custom AV installer with a background in car stereo. We like to find ways to make things happen, not overstate the problem. Good luck.

I don't see that being a problem. But I have never tried to run any speakers with that impedance. I did a little research and found this sentence in a post:"Marantz doesn't officially rate their receivers for 4ohms either, but they do just fine with 4ohm speakers. Marantz reps will tell you that its OK with most speakers. A lot of Yamaha receivers are rated for 4ohms, so the 667 would be another option at the $500 price point." I found this on: http://forum.blu-ray.com/showthread.php?t=162749Good luck!

I drive a pair of 4ohm Legacy speakers on a Denon AVR-1513 which is only rater for 6-8ohm. My Infinity center is 8ohm which handles most of the audio, but even in stereo mode the 4ohm Legacy's sound great and the Denon doesn't appear to operate unreasonably hot. No problems after months of use, but it's not like I turn the dial to 11 either.

I'm driving 8 ohm speakers without any trouble: Energy 5.1 Take Classic Home Theater System (Set of Six, Black)

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.

I haven't run 6 ohm speakers myself but have read dozens of reviews from people who have. This receiver is excellent and I recommend it. According to the community at large you will be fine driving 6 ohm impedance speakers with this receiver.

It is rated to handle 4 ohm speakers. When my first unit died, however, they kept asking me if I was using 4 ohm speakers and then kept reassuring me that it was able to handle 4 ohm speakers. I don't know what that means, but it gives me pause. It does have two zones.

I have mine connected to 4 ohm Polk speakers and it works perfectly. You should not have any problems with 6 ohm speakers. The Motiva is a lot of power for a reasonable price.

You should have no issues with hooking up your 6 ohm speakers. We have multiple speakers set up in ourhouse and in my shop. I have two of these units and they work great.

This unit is built for output impedance 4-8 Ohm. By using 2 Ohm speakers you are risking to burn unit amplifier; this is not really high end equipment. This unit has RCA output and option to attach an amplifier; that would be better way to go.

the four ohm speaker will work just fine in this application, but it will not be as loud as a two ohm speaker. the ohm in this sense is a unit of resistance, and the higher the number the more resistance you have. that being said, finding a two ohm speaker may be a bit of a chore. good luck!!

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.

You should be fine, but just to be on the safe side, look on the back of the amplifier or in the owner's manual to see if there is a specific warning not to drive speakers with less that an 8-ohm load. Since it's a good-quality amp, there shouldn't be a warning of that sort. As a further check, see if the manual quotes a power rating into 4 or 6 ohms. It probably will (and it will be a higher number), which means your unit has the reserve current to safely drive a lower impedance speaker. Hope this works out because -- having lived with these speakers for more than a year -- I continue to be impressed by their clarity and the width of the sonic field they are able to project.

I checked the specs on this amp and it is two ohm stable. No need to bridge. With just these 4 speakers and single amp, you should get 100x4 @ 2 ohm(RMS). Which is within the range of the speakers. The Peak power is 235x4 @4ohm, which may be slightly higher @ 2 ohm. This is just above the recommended power for the speakers, which should not pose a problem as long as you don't max out the gains and volume on the head unit.

what is the true ohm load at 4ohms and would it really push 4- 15 pa speakers with power to spare?
1251203
If your amp can handle a 4 ohm load that means you can hook two 8 ohm speakers up per side. That's 8+8 =4 ohm. You Re fine as long as the total resistance of your speakers are 8 ohm speakers.IF you run two 4 ohm speakers per side you get 2 ohms etc.You could also wire the two 8 ohm speakers I a series and get 16 ohms. To learn more about properwiring and Ibm's law you can find it at 12volt.com

I don't own this but am considering this. The manual shows an audio out so you could go into an amp with that. The speakers are 3 ohms and have a jack on the side that would allow you to power a speaker, if you could get or make the same connector that they have. The issue will be the 3 ohm 7 watt rating. typically speakers are either 4 ohms in smaller units or 8 ohms in larger speakers. You will see less volume with speakers with a higher impedence with 8 ohm speakers being only about 1/2 as loud as the 3 ohm speakers that are supplied with the unit. There could be other problems with impedence mis-match but I haven't tried it to know.

This is just an educated guess, but as long as those speakers are 8 ohm, it would drive them. I believe with room to spare!

Yes it will work for 4 ohms speaker Less than 60 watts per channel Unit is very bad, pictures looks awsome But not real function Better to get vintage receiver for $50 It will way better than this Good luck

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!

I have not hooked it up yet. On my receiver though I have separate sub woofer outputs. Put if you do hook it up in parallel it would be 4 ohms. Most systems are ok at 4 ohms.
