Muffled sound - help please

Posted by: steveaxe on 01 October 2018

My system consists of  HDX-SSD, NAC 202, NAP 200, Ovator S400 and Chord Mojo with Apple Express for streaming. At the weekend my teenage children had a party and used the system with the Mojo, and now the sound is best described as muffled. The stunning clarity I once had has been replaced by blurred bass, poor clarity and overall it sounds terrible. I can only presume they had the volume too loud. I would really appreciate any advice on how to both find the problem and also how to fix it. Many thanks in advance of any advice & support.

Just back from holiday, so only seeing this thread today.  Many years ago a colleague complained of a similar problem (no Naim equipment involved, though).  I went round to his house, pulled off the foam fronts of his speakers (can't recall the make), to find a couple of socks stuffed in front of the bass/mid drivers!  I assume the OP has checked for something similar?

If the BMRs are ‘fried’, the said offspring paying fir them, whether out of pocket money, paid work, no birthday/Xmas presents, or sale of mobile phones, would bring home yo them the need for respect and control...

(But only if they had been either prohibited from using, or pre-warned about maximum volume.)

Don’t blame the youngster. Blame the Tories or Brexit.

Yes, best to teach them not to have any self responsibility and blame anyone other than themselves for their own mistakes.

Not sure wrecking the speakers (if that is what happened) is the main issue. Accidents do happen.

It would be the obvious attempt to pretend like nothing is known about the damage and come forward.

I would say, if indeed the speakers are munted it was a friend that did it. After all what are friends for. What would be more of a wreck would be if a lp12 was left out to be used! (Which is not the case)

 Sharing is caring after all.

Anyway with respect to the OP, I’m sure things have been said and the situation is at the fixing stage. After all I do seem to remember crashing my Fathers 550hp sport car back the late 90’s. I disappeared for 3 days  hoping he would cool down...nope he didnt????????

gee the power came on fast. Whoopsies, sorry Dad.

 Teenagers having a party, music as loud as possible, strong bass beat overwhelming everything, lots of drink (hopefully nothing more), dancing, snogging...   maybe they genuinely didn’t notice, being sufficiently intoxicated and deafened (and likely one BMR  went first, not both at same moment, making less obvious).

Of course not all parties are like that (shame!)

Home DIY diagnosis done - other speakers work perfectly so it’s the BMR’s. Spoke to the dealer and getting a quote. The nervous part .....

Glad you've narrowed down the issue Steve. Hopefully returning your Ovators to full health won't be too expensive.

Insurance claim? Accidental damage.

there is good news and bad news on my system. the tweeters are fixed (at a cost of 500 Euros !), but the base simply doesn't sound right - it sounds unclear and booming. do you think its a speaker issue again or could it be the amp this time ? any advice gladly received !

Steve - I take it your dealer did the BMR replacement, tested both speakers and declared everything ok before returning them to you ?

Posted on: 02 January 2019 by steveaxe

On my way back to the dealer with speakers and the amp to try to find the problem ....

Posted on: 02 January 2019 by james n

That sounds like a good plan. Let us know what you find...

Posted on: 02 January 2019 by steveaxe

Just done / no issues with the equipment so it’s the speaker positioning and allowing the amp to warm up. Finally a cheap solution !

Glad nothing serious was amiss, yes give it time to all settle down and let us know in a few weeks time.

Good news

And don't forget that Ovators take an age to settle down.  You've moved them and had them repaired, and then had them moved back home.  It'll take time.

Good point - will give it a few weeks to run them in
