Guys,

Can anyone confirm if I will have any issues with 4 ohm speakers on a Denon 4310... Google isnt very helpful.

Id especially like to hear from anyone first hand running 4 ohm speakers with a 4310.

jason there are some info in the htfaq on the topic.

It simply is not a case of just 4 ohm speakers. you could hook up some peapod 4 ohm speakers and the 4310 wouldnt break a sweat.

also keep in mind the impedance qouted on speakers is just nominal. ie it varies with freq trying to reproduce. Its usually with lower freq reproduction that impedance drops. so a nominal 4 ohm speaker will likely drop to 2 ohm at power sapping lower freq. ofcourse if using a sub then this is of less consequence.

Also impedance is only one factor. in the end its about just how demanding are the speakers your hooking up. And be realistic in what you are expecting an avr with a limited power section to drive. If you are indeed driving some seriously big low efficiency, power hungry hard to drive behemoths then your better off using a suitable power amp.

your speaker manufactuer is likely to give you better advice as to whether it would be a suitable driving your speakers or are you better off utilising a power amp.

Thanks heehe

Well they are floorstander's if that helps (rated around 150wrms), possibly be looking at the either Ascension speakers or the Krix harmonix. In teh ascension range, all the other parts of the 5.1 surround system are an 8 ohm speakers.

Well, I was running VAF I-93 Signatures with the older Denon AVC-A1SR without any issues. They are rated at 3ohm nominal impedance (2.8 ohms is what Philip Vafiadis said they were actually). Admittedly that amp did pass THX Ultra2 certification which does rate it stable for 4 ohm loads (down to 3.2 ohms continuous I think).

With the 4310, I imagine that it would do 4ohm loads fine as long as you don't up the volume too much and try driving the speakers full range. If you cross your speakers over at say 80hz, you probably won't have too many issues as the amp should have enough headroom left for all the mid and upper frequencies. The low impedance issues usually only comes in when you try and crank the volume in the bass regions as the impedance usually drops and a lot of integrated amps just can't keep up with that kind of current draw.

Anyway, since you are set on those 4 ohm speakers, unless you decide to switch to THX Ultra 2 certified AVRs which are guaranteed to be stable into 4 ohms, if you like the Denon, then just buy it and try it out. If it doesn't work out well, then consider yourself lucky as now you'll have a GREAT excuse to go and grab some external amplification and enjoy real amplification

Thanks guys for the responses. Ill think ill stick with 8 ohms so I dont overdrive my Amp.

If you are looking at Ascension loudspeakers, give Edward a call and have a chat. I think you will find he can build the crossover to what ever value you desire. Tell him what electronics you have, what you need them for and he will give you sme options.
