AV receiver that can drive Wharfedale Diamond 9.5

[karmapilots]

Hello,

I recently got Wharfedale Diamond 9.5 and thought of pairing it with my existing Yamaha RX-V730. The output power of the receiver is 75W at 8 Ohms and the speakers power handling is 30-150W at 6 Ohms. This a link to the RX-V730 page. RX-V730

Once I connected the speakers to the receiver it sounded very feeble and I had to really drive up the volume to 30 to hear the music. Earlier I had a DIY speaker connected to this receiver and that used to work fine.

Guys what might be the problem? If the receiver can't drive these speakers then which new one should I go for? Please help.

Thanking you all in advance.

Did you change speaker impedance to 6 ohms in receiver?

I have Yamaha RX-665, selected 6 ohm and speakers worked fine with that.

Hi Karmapilots,

I've connected my Sony BS to the Onkyo TX-SR608, and learnt that I need to increase the volume to atleast 35 to hear anything from them.

From my understanding, The volume level range is 0-80 and hence 35 should be quite nominal - as against common-place hifi systems and appliances.

Just my thoughts. Please feel free to correct me.

Hey Pannags,

My volume range is from 100-0 and in that I have to keep 30 for something to be heard. That is 70% of the volume and then I think somethings not right.

Oh!! will try that. Thanks.

Hey Netfreak,

I changed the impedance to 6 Ohms. Its better now. But still needs to crank up more than the old speaker. Any other suggestions, any one?

don't condemn your reciever yet.. your DIY, esp if it was made with indian components, would possibly be much more efficient (but maybe not better), therefore you have to crank up the volume control more for the wharfies. but that's not the reciever's fault.

if you read online, the 6ohm/8ohm setting only does some current limiting.should not have anything mroe than a placebo effect.

on the issue of more power, do remember, than doubling output power with the same speakers only increases sound volume by 3dB. incidentially 3db is the mimimum vloume change that can be discerned by most people.

you should see if, on cranking up the volume, you speakers play loud and cleanly. if they do, don't worry any more..

on the other hand, if you are still not convinced, there's where you can get much powerful receivers (excuse the shameless plugging)

Hi Folks,

I have a similar problem. Instead of starting a new thread thought i would continue here as the problems are related.

My rx663 allows me to set speaker impedance to 8 or 6 ohms. But my front left and front right speakers are 8 ohms, center and surround are 6 ohms. In such case how should i set the receiver?

Can i set 6 ohms in the receiver and drive my front speakers[L&R] which are of 8 ohms? will it damage anything. What would be the best suggestion?

Thanks,
Prakash.

 

[kapvin]

your main speakers are the ones that get the most load. so the AV should be configured to best handle them.

however, as you may seen in the previous post, if you google, you'll see that most people dont' see a positive effect to setting 6ohms even with 6ohm speakers.

in your case, it should be on 8ohms anyway.

cheers

Hey Kapvin,

Thanks for the info. Placebo, I would like to agree. I was a lil worried to crank up the volume. But then I tried it and its working good. Was worried whether some overload will happen.

Your RX-v1500 is very tempting. But I'll wait and get a Emotiva(like you) or a Bryston in the future.

Thank you very much and good luck with your sale.

Sham.
ps: And thats a load of stuff that you have and no wonder your wife reached the end of her patience.

Its risky to use 6 ohm speakers without selecting 6 ohm on receiver. This might lead to more current than expected and receiver might run hot.

That was one of my fears more than SQ. So now that its in 6 Ohms I tried driving it up and it sounds good.

 

[NetFreak]

Yes its wont affect SQ, but since this would limit the amount of current you can push the volume bit higher.

My experience -

1.Used a RX-V440 (65W x 6 @ 8 ohms) with the 9.5s for a couple of months. Volume at -35 used to give very good and clean output. Rarely ever needed to cross that limit. Tried it with the 6 ohm and 8 ohm settings as well. Didnt make any discernible difference to me.

2.Using the 9.5s with a Denon 2310 now. Generally use it with a -10 volume setting below the reference level set by Audyssey. This AVR does not have a 6/8 ohm selector. Heat generated even during prolonged use is nothing to shout about.

My layman feeling is that during normal listening, if the sound is not distorted, then chances are that the AVR is able to feed the speaker with what it needs. If the slightest distortion is heard though, its time to ease up on the volume control. Of course, 'no distortion' could also mean that the AVR, though functioning within safe limits, has nearly reached its limit in driving the speakers. While this would not matter much in the normal course, it will severely limit the AVRs capability to faithfully reproduce 'transients'. This could impact movie watching.

8 ohm setting should be quite sufficient to drive 6 ohms speakers. Also, as noted earlier, impedence settings are meaningless for AVRs.

Some of the companys inflate the specifications, particularly for their entry and middle level AVRs, ex. Onkyo, yamaha etc, to market them aggresively and people without knowing the hitch puechase them thinking that they got it for a lower price when compared to other similar rated ones which costs more , ex. Denon , which stands to the mark for the given ratings. Once we play them on standard speakers , which are power hungry, the hollowness of these AVRs exposed, as it was in the present case.

I gues this should help you understand how these switches are meaningless at best and detrimental to Sq at worst
