Speaker burn in
« on: March 10, 2022, 05:35:07 AM »
 :duh
How do we as consumers of high end, expensive speakers, accept the fact that the speakers we've just purchased will not sound their best until we reach 500 hours of play? I'm following owners over at Aucdiocircle's Spatial Audio group and they seem just fine with it.
Just think. If you played music through your speakers 24 hours a day, it would take 21 days to be fully broken in and playing at their full potential.
Now don't get me wrong. I'm not saying burn in is bogus. I would expect burn in to be done by the manufacturer and when they are at my home, they will play at their full potential.
So why isnt it done? I'm not picking on Spatial. Many if not all do this. Is it cost? How much could it be?

Years ago I remember Danny Richie showing graphs of his before and after break in.  The vast majority of change happened in the first 3 hours- mechanical break in.  Electrical is another thing altogether.  If a manufacturer pitches huge changes after 500 hours, I suspect he's simply making it harder to return an item.  Again, not saying there is nothing to it, but I'm not waiting 100 hours to evaluate gear.

It is more a question of space.  Imagine having anywhere from 20 - 500 speakers burning in.  Then there is the cost of amplification...

Maybe begin to burn in speakers and crossovers prior to assembly?
Cost of amplification? No answer for that. Just need quantity. Not quality.

 Spatial Audio are built to order. How many speakers from big names like Magnepan and Vandersteen build a day?

Amuse me. Just a pet peeve of mine  :lol:

  Our Qln line requires 200 hours. We allow for break in for return. None have been returned. We use 12 hours on 12 hours off after intial 48 hr burn in.

Vandersteen breaks in 60 woofers at a time by doing series/parallel wiring and plugging them into the wall AC!  Even wiring every other one antiphase that has to be quite a roar!

I get your angst.  That is why I ran every component in the BUSSes I built for 3 days at 240VAC.  Both for durabiity testing as well as trying to pre-bias the film in the PFC capacitor network.  Even so, during shipping that pre-burn will relax somewhat and they had to go through final burn-in. 

Think about pre-burn on a high quality crossover and then having the completed speaker sit in a box for a month. Gotta do the whole break-in thing again.

I agree. I believe that if a component youíve purchased doesnít sound good to your ears after a couple of hours, itís not for you. I own Spatial speakers, and look in on the AC circle about them- it seems that no matter the issue, more break in is required. I liked mine and the way they interacted with my problematic asymmetric room. Break in, in my mind, is incremental, and will not change the fundamental character of a piece of equipment.
I donít care if itís a DAC, a speaker, an amp, etc., if you donít like it, you donít like it. Iíve bought a lot of gear over the years- my first impressions did not radically change.
Speakers, electronics, cables, etc., can contain many components- how in the world can a manufacturer claim theyíve listened to all the associated variables and put out the product they feel is their best effort. Maybe thatís where the MK2 comes into being.
I donít mean to be a Debbie Downer about this, but in my experience, if you donít like a piece out of the box after itís been in your system for a day or two, itís probably not for you.
Charles said QLN requires 200 hours- I loved a pair with minimal hours- I can imagine Iíd like them even more as they break in. I donít think anyone took them out of the box, listened, and said ďI donít know if I like these, but Iíll give them more timeĒ. I guess itís a difference of great and greater.
Rant over- I believe break in is real, but I donít believe itíll turn something you donít like out of the box into a winner for your earsÖ
