Can someone please calm me down… again…
All fine with PN
The accident happened for the first time.
Switching from vinyl to streamer - forgetting to adjust volume.
Thankfully no loud part of music. But too loud.
Checked the SBL tweeter and woofer - looked ok. No bad smell.
Made several listening texts - voices and piano. Bass tracks.
All fine sounding like before. Not any distortion…
Sounding as perfect as yesterday.
If there has been any damage - I should have known instantly… correct?
Please be careful with your answer … it is Drago-time :o/
Damage from excessive volume would be audible (and highly unlikely to be visible). Audible would be either distortion, or a rasping/rubbing sound.
Brief overload unless extreme rarely damages things. Extreme would be likely be things like disconnecting/connecting a source with volume turned up, or disconnecting/connecting the interconnect between pre and power amp while the power amp is powered up.
If I understand correctly… even if it was too loud for a split second and maybe not clear in sound at this volume (could not remember as I paused in immediately) it rarely damage things.
If damaged…
I would have known by now. Distortions, rasping or even no sound from e.g. Tweeter.
And damage also includes the crossover? If damaged here, I would have heared it also?
So there is no degradation in sound likely - which especially I can bring up in mind very easy. Damage to crossover and speaker is not subtle - once happened … you will know
Summing up. As my SBLs sounds fine with no audible distortion no damage has happened to speakers or crossover. Correct?
Sorry for freaking out (again) but with PN I really balanced the system so that I think there is a sweet spot, which I really like to keep a bit.
Damaged LS would not be very compliant to this…
Thanks a lot - had a call to my dealer (PN Topic) and asked him.
He pictured its the exact same way.
No problem - if only a moment… You will hear instantly if there is any damage. When the crossover blows - there is at least no sound or massive distortion on one Loudspeaker. And the crossover is more resistant and normally does not blow first.
Quote: “this (switching to loud channel) has happened a lot during my hifi career - never had any damage in LS.”
This does not mean, that in will do this every evening.
PS: Checked the woofer via woofer test and they are floating as before - no cracking
It’s a pleasure. I have personally had two instances blowing speakers: One when the moving coil input stage of a preamp went into oscillation while playing very loud – despite dashing for the volume control, one speaker’s woofer voice coil had buckled with the heat, and although it still played it was accompanied by a noticeable rasping sound as the coil scraped the sides of the magnet gap. The other when I inadvertently powered on my DAC with the amp already on, the resultant very loud pop damaging a midtange drive unit, which then distorted very noticeably at certain frequencies.
@drago to further reassure you, I managed to set fire to one set of older Sony speakers playing them at at outside BBQ with the amp on full volume for maybe 10 hours before they died and then it was only one of them. I also blew a tweeter on a pair of Focals some years back by playing music in a room so it could be heard outside. The volume was so loud I had to cover my ears while in the room. Maybe 2 o’clock on the dial or more.
I have had SBL’s and NEVER have they objected to a bit of volume going through them.
If the speakers are damaged you can tell. You CAN tell!!! Never worry again because if it sounds fine it is!!
Thank you so much - my world is back in order.
My mind has played bad tricks yesterday. Suddenly sound was different - but it wasn’t as ears told … but mind was mighty.
Love the sound sooo much.
Think I have a sweetspot now… this is hard to achieve when climbing up the ladder as you all might know
I know - must be strange … feeding nd555 /52/135 into SBL (mk1 actually) … but SBL is … it is special… very addictive.
The woofers look like new … even they are really not.
The N10 is better, but do you have some place left for it? It’s 2 boxes. But be prepared to buy more albums, the difference vs Qobuz will be significant, specially if the albums are well made. It will be the same jump as from EE8 bare to PhoenixNet, even perhaps greater.
@frenchrooster I had the N10 in question and the difference between local streaming and Qobuz was only small. A few % most of the time. The BIG difference is that almost all of the music on streaming services is the new remastered releases. There is no indication of mastering. I now have the SSD N10 and that gave a nice uplift vs the older model. More organic sound, local streaming vs Qobuz is also VERY close, maybe even closer. I like having my music organised and titled as I want it which is why I have a server, the Melco is part of my chain so listening to Qobuz still routes the sound via the Melco. Vs direct to ND555 I prefer via the Melco.
Melcos SSDs have lot of extra shielding and are selected based on low (RFI) noise etc. I have tried replacing the HDDs in my Melco with a few different SSDs but it sounded worse with all of them, I found one make of microcontroller (used inside the SSD) sounded better than the others but I have forgotten the name … I switched back to the Melco HDD drives.
