Denon 2312 with 4ohm speakers

[vagrahb]

I have been a silent member and I recently happened to get my hands on a good deal for Denon 2312 receiver. I have a couple of speakers 2 fronts and a center which are of 4ohm nominal impedence(Krix Tryptix). I just wanted to know if anyone has a setup driving 4 ohm speakers with a Denon AVR. I know the best way is to have an amp drive these speakers. I don't intend to drive the AVR to its potential and I think it should be fine but just wanted some input from you guys.

I am using 4 ohms speakers with my denon 1612. It is advisable not to crank up the volume too high as it may damage the avr and speakers. I have limited the maximum volume to 71 and the normal volume to 50. I intend to upgrade the speakers ASAP, as sometimes the avr power button will flash red continuously on powering up which means lower impedence issue. I need to press the power button again to start the avr normally.

2312 is a fairly powerfull AVR. Should be able to drive 4 ohm bookshelf speakers to reasonable levels.

I have been reading some interesting stuffs here are they on this topic

Speakers Glossary

Peak SPL Calculator

it seems that nominal ohm (the impedence) of speaker for these kind of AVRs ( onkyo, denon and not the sony, samsung, lg etc) varies from 6 to 8, and if you look at specifications on AVR, it will give more power 'W' output with 6 ohm than 8, well that means if you are driving your beloved AVR for quite less ohm (4 ohm is this case which is almost half for their specification) the AVR will pump out very large current since there is very less resistance (ohm impedence) from speaker coils so there is a lot of chance you will make AVR hot and ever trip it, as observed by baiju above

it is also interesting to note whts db specification of these speakers, again it seems it will be quite less, which from the link I posted the AVR has to pump in a lot of Watt to drive them to get your desired output which is not good again.

we often think that if a AVR is having large Watt output it will be good but thats not, even the entry level AVRs denon 1312 or onkyo 3400 (disadvantage with 3400 is that it does not have subwoofer pre out due to which you wont be able to upgrade its sub) can drive towers preety good since many of the towers are 6ohm with around 110 db sensitivity which doesn't need a lot of power to get decent household sound volume

so again if you love your AVR and spent a lot of money then spend few more to get a suitable speakers to enjoy at most

I read in avsforum, the geeks there suggest you spend almost double the money for speakers than for AVR, an avegare AVR with gr8 speakers can blow you away but not the other way round

 

[sajankalathu]

You are correct saj, AVR will not burn with a 4 ohm speaker but it will go to protection mode when you increase the volume. I am also suggest you to buy a tower speaker of 6 or 8 ohm.

I really love the speakers I have right now. so will try and get a amp to go with them. But until then I guess I shall just see what happens (Fingers crossed)

Just get an active subwoofer and set the cross-over in the AVR for individual speakers at 80 to 100 Hz. That would transfer the low frequency (current guzzling) signal to the sub and relieve your AVR off the load ..... This solution is a lot cheaper and more effective .........

 

[saj2001ind]

just increasing the crossover freq wont help, its just redirects the low freq to sub, on a low OHM speakers the AVR will draw a lot of current anyways...

the thumb rule, if you are stuck with 4 OHM speakers then dont go loud or dont overload ur AVR to protect it

Theoritically YES ......... but, Practically NO.
OP has a 2312 .... a significantly powerful AVR. So, adding a sub here would make his system very safe as 'extra' current draw would be terminated.

 

[saj2001ind]

I wont agree to this theory that doing a crossover freq will allow the AVR to draw less current, have you read any article/forum ? can you give a reference ?

 

[avidyarthy]

I have my own example to take ......

Pioneer 519 AVR is a low powered one, no match to 2312. It is running the Wharfedale Moviestar speakers (5.1), all wall mounts with 4 ohm rating. There used to be some issues at loud volumes initially when it was set up by the installation guys. They had kept the XO at 60 Hz for the speakers. Later, I increased the XO to 100 Hz ... and viola.

Hi avidyarthy

I got the yamaha rx-v571 model recently. Currency I am running my sony bookshelves with 6 ohm rating for the front L/R channels. I have a samsung htib with 5 satellite speakers at 4 ohm rating. Can I use the 2 speakers from this and use it for as surrounds for my 571 receiver. Will it not cause any problem if run in medium to low volume. And if yes can I use the automatic calibration (YPAO) with these speakers.
I am waiting for my energy rc-micro speakers from US and will be getting it only by the end of March. So hoping to utilize the existing speakers if it is not affecting the receiver.

Thanks.

I dont want to argue with you but theoritically its not possible, I will not agree untill I see any article explaining this, I have been doing a lot of reading in avsforum and in touch with some senior experts there, and with that it is confirmed that crossover is mare redirect of lower freq to sub which will not have any significant impact on current dwarn from AVR when running low OHM speakers

if somehow you feel it worked for you, its good, but again I will need to see some technical explaination for this.

if you find any on this pls share. and I am happy your setup worked.

Using 4 Ohm speaker with these AVR is always not adviced in general, as it draw more current from ur AVR. Increasing the crossover will only safe gaurd ur speakers not to blow off in high volumes..If you still want to use Take care of the Volume not to go high . .

It's only been a week but i have not seen any problem in my Denon 3312 driving the Lsi9 which is a 4 ohm speaker. i have taken precaution of not increasing the volume too high but have continuously used for 5-6 hrs..

Lsi9 as per specs says its 4 OHM Nominal which does not mean its 4 OHM strictly, but its variable and I am sure its a professional speaker so while u r driving it with denon 3312 it wont be at 4 OHM, rather at least 6 to 8

I have a Denon 4308 and just got a pair of LSi9. Id like to power the
in 2 channel only with my Denon. Can you tell me how your experience has been since your last post.

Thanks a lot

I wont agree to this theory that doing a crossover freq will allow the AVR to draw less current, have you read any article/forum ? can you give a reference ?

anyone who knows anything about powering speakers knows that 80 percent of the power goes to powering the bass. that being said how can anyone intelligently think that there would be no difference to the strain on the amp when you remove what is the majority of its work load. Amps don't just draw the exact same amount of power no matter how they are being used... if you have your stuff loud for a long time it will get hot. If you play it really really quietly for 14 days straight it will never even get lukewarm. and amplifiers workload is not just some fixed load based solely upon the speaker connected to it. OF course adding a crossover will lighten the workload and the higher the cross over the lighter the workload on the amp. End of story.

I don't really understand what you mean by it being a "professional speaker" and how that means that it will likely operate between 6&8 ohms as a result of it's perceived professionalism?

Please elaborate.
