Nova - Blew speaker

Are you Sure it’s the speaker? Try swopping around, unusual for both drivers to go

I agree. Much more likely to be an amplifier fault, but swapping the loudspeaker leads will tell you immediately.

I am worried for my Nova now. I have also observed similar behaviour - all of a sudden the volume going high. No speaker blow up so far fortunately.

However, I keep my volume at 50% level because of that reason max (through the setting). But overall this is unacceptable.

Not sure why they have not put any measure to always keep the volume at current level irrespective of what the player's volume is. User may want to override this setting.

This is a serious concern and Naim should address this immediately.

Guys I am very upset and totally frustrated, thanks for the suggestions, but I powered it down from the mains and left the house for some time out, as I thought I was going to grab the Nova and throw it in the bin.

Do you think it is the amplifier has blown, as I put my ear near the right speaker the tweeter was distorted and the main driver nothing.

So suggestion is swap the amp connection to the right speaker?

Given they are beryllium tweeters this is going to be more painful on the repair, will have to find a dealer, but did it think they repair, that's more back to France (Focal).

Sorry to hear news of your woes. Just a thought, if it is speaker damage, do you have the safety pack to seal the Be tweeter before sending back?

theres a risk the factory may not handle the unit if not protected, due to hazard of material in tweeter.

these are supplied with the speakers when bought.

So what I think has happened is that your Nova has developed a fault and your speakers are still fine.

If you unplug both speakers completely and plug the left speaker into the right speaker connections on the Nova and the right speaker into the left speaker connections on the Nova, does the non functioning channel stay where it was or does it swap to the other side?

If it stays where it was then it's a loudspeaker problem and if it swaps sides it's a Nova problem.

its fine to do this swapping at the Nova end without turning the Nova off. But I guess it's off anyway now, so change the two speaker cables over as per above and turn on again.

For the avoidance of doubt (!) I am saying change both plugs from the left speaker from the left sockets on the Nova to the right sockets on the Nova and the opposite with the right speaker.

I will keep an eye on this thread so let us know what you find!

I would feel more inclined to try another amp rather than plugging a potential knackered amp into the remaining good speaker.

I’d agree, just connect the suspect speaker in to the ‘good’ side and see it if it works 

Yes I agree just connecting the suspect speaker into the other side of the Nova and see if it works would be safer.

But the Nova shouldn't make those noises under any circumstances so whether or not it has damaged a loudspeaker, the Nova is going to be replaced by the dealer next week.....

To be fair there’s still a funny with 2.6.1, not sure of the exact situation that causes it but it’s happened to me a few times. I think it’s when youre controlling the volume via the app and if for some reason the app has disconnected from the unit and you go and adjust the vol manually on the unit itself the volume will blast, I’ll pay more attention next time and report it officially so it’s noted. 

If you report it to Naim and also tell us here then the beta testers (those with new Unitis anyway) can look out for that specific issue.

So do the amateur lawyers amongst us think that, if the Nova is faulty and it has damaged Obsydian's speaker, he's entitled to restitution by Naim (i.e. Naim pay for the repair to the speaker).   A quick look to see where Obsydian resides doesn't tell me, so I'm not sure who's laws apply, but while we're still in the EU, there's some similarity there, and if in the USA, I've watched Judge Judy enough times to know the answer... 'yes'. 

Let’s be fair, has he contacted the dealer, have they contacted Naim....the thread does not support any request for help from dealer or Naim. The legal stuff should be a last resort, and is not for the forum.

Yes I agree Gazza. Let's help him find the problem first.

I would imagine it would be very difficult to prove liability in a case like this even if the Nova is found to be faulty how can it be proved that it was faulty when the damage was caused to the speakers.

Hmm, this is how mine was sounding last night on 2.6.1. It sounds distorted in high frequencies and rather unpleasent. 

Carefull with that blown tweeter - just read inhaled beryllium-containing dusts can cause a chronic life-threatening allergic disease in some people called berylliosis.

We/he doesn't know it's blown yet!

All many thanks, one of the things I have always loved about the forum is help and advice.

Short version, speaker has not blown, but do not sound right the top end dynamics gone, soundstage also seems off ( I think), I want to rest and listen tomorrow.

I returned home saw the comments and decided to first switch the Nova back on from the mains and then a while later out of standby, all fine, BUT oddly like a new setup start, even the app later was saying register the product???

I also panicked reading CBR600 comment then started scrambling for my tweeter safety sticker and jiffy bag, as also wanted to examine the drivers. Fortunately all drivers in particular the tweeters were fine, I was thinking do I need to wear a mask.

I wanted to first assess the issue at each speaker driver, in particular the right tweeter and driver as that had no sound.

Playing a The first track all drivers are working, I then listened to a few more tracks, felt it does not sound right and quit whilst I am ahead tonight.

I feel as if the Nova had some major shutdown meltdown, I am hoping the speakers are fine but Monday will find a Focal dealer and get some advice.

Will also be calling Naim on Monday as lost all confidence in the product and feel like each power on or off, I will now be clinching my cheeks for the next bang.

I would be very sure that your speakers are fine and your Nova has a major problem, which is why it made that noise on switch off  and why it sounds terrible. Maybe also that's why you haven't liked the sound for weeks. So get your Naim dealer involved asap. I would be very surprised if you needed to talk to Focal at all.

Many thanks Dave, i really how so, will listen tomorrow with a fresh pair of ears.

Thinking back, the power down was a bloody loud sharp plop, then abruptly cut power (usually I get a nice relay click and a very slight barely audible speaker pop)

Will speak to Naim Monday and try to understand why one speaker/channel had one driver no sound and the other distorted.

I had the max volume issue before, but that was listening 7AM one morning and it just went MAX, but nothing like this.

Obsydian,  best speak with Naim on Monday.  If there's an issue they will want to know.  You've been having some sound issues for a while now so probably best to have your Nova checked out by the factory.

Glad your speakers are ok. Be good to hear how you get on, as I feel mine is a Lemon and this is why I dont like the SQ anymore and the other issues I keep running into, rando locks and random SQ changes.
